TRACTUFF K20Z3/ K24A2 WATER BYPASS ADAPTER**Now included: 1 x 90 1 2" NPT to 5 8 hose barb, and 1 x 1. 00 hose clamp** Our K20Z3 K24A2 water bypass adapter allows RAA, RBC, RBB, and RSP cylinder head owners to run the more popular aftermarket intake manifold options that were designed for the earlier PRB PRC flange. The PRB PRC style manifolds do not have an integrated coolant passage so the coolant bypass hole is left open when used together. Even if you don't plan on running a PRB PRC style

**Now included: 1 x 90° 1/2" NPT to 5/8” hose barb, and 1 x 1.00” hose clamp**

Our K20Z3/ K24A2 water bypass adapter allows RAA, RBC, RBB, and RSP cylinder head owners to run the more popular aftermarket intake manifold options that were designed for the earlier PRB/ PRC flange. The PRB/ PRC style manifolds do not have an integrated coolant passage so the coolant bypass hole is left open when used together. 

Even if you don't plan on running a PRB/ PRC style manifold... there are plenty of benefits that make this product a must have! The biggest benefit is in the reduction of intake manifold temps by eliminating the heat transfer/ heat soak associated with hot coolant running through the manifold. By modifying the manifolds flange (cutting off coolant portion) and running our adapter the coolant is kept away from the manifold completely, just like what you would find on the earlier PRB/ PRC heads, so NOW your Hondata IM gasket will really work!! We've seen drops as much as 18°!! Not to mention, the additional benefit of no longer having to drain the coolant when removing the intake manifold for maintenance or swaps... makes things a real SNAP!

 

We recommend a TracTuff Bypass Hose Fitting when connecting the OEM bypass hose.

Installation Guide

 

 



 

 

Start by selecting one of the two o-rings (one is a back-up) and install it into the recess on the adapter’s backside. Set the adapter aside.

 

 

 

 

 

 

 

 

Grab the stainless steel link and longer 40mm Genuine Honda flanged bolt and install the bolt into the smooth hole in the link.

 

 

 

 

 

 

 

 

Install the bolt and stainless link into the right-most intake manifold flange bolt hole. Tighten lightly with the link facing upward.

 

 

 

 

 

           

 

 

Grab the shorter 28mm Genuine Honda flange bolt and adapter and install the bolt into the lower bolt hole.

 

 

 

 

 

 

 

 

Take the bolt and adapter and install it over the exposed water & egr ports. Thread the bolt into the cylinder head until it is hand tight.

 

 

 

 

 

 

 

Grab the stainless steel set screw and thread it into the stainless link. The pointed set screw will tighten into the hole well but in some extreme cases it may be a good idea to use some medium grade Loctite.

 

 



 

 

 

 

 

Swing the stainless link and set screw down until it lines up with the pilot hole of your choice.

 

 

 

 

 



 

 

Tighten the 8mm intake manifold and Water Bypass bolts to 18 lb. ft. of torque and tighten the set screw until you have sufficient crush on the adapters o-ring. Congratulations! You're done.

A cat, a murdered author, and a librarian cum sleuth - what more do you need?
Format: Kindle
Murder Past Due has it all. A small town where everyone knows everyone, return of the prodigal son, murder, and a just-nosy-enough archivist with connections to them all. My favorite character is Diesel, the cat, though his primary role is as a comforting presence. I would have been happy with more of a supporting role for him—there were a few moments where I thought he would get one, but it didn’t quite take off. The mystery engaged me and kept me reading. I had it nearly figure out in the last fifty pages, but there were satisfying twists leaving me pleasantly surprised right up to the end. I was distracted by excess verbiage (Southern style?), and something ever so flat about the main character. He said he was surprised or upset or missed certain people, but I just didn’t feel it. Still, I think I will read book two, and that merits a solid four stars.

The cat didn't do it!
Format: Mass Market Paperback
I bought the book, because it looked so cute. Plus, I love cats! It was a cozy mystery with the cat as a constant companion of the protagonist. It made for a delightful story. I don't usually read low key mysteries, but I thoroughly enjoyed the humor, the cat, and the murder mystery. I plan on buying the next one. Ms. James has a writing style that you will enjoy her stories. You will not get bored.

When A Mystery Writer's Death Becomes The Mystery
Format: Kindle
Charlie Harris is a part-time archival librarian for Athena College in Athena, Mississippi. In his late forties, the father of two grown children, and a widower for three years, Charlie is the proud human owned by a Maine coon cat named Diesel. Still grieving the loss of his wife, Charlie is not yet interested in dating and keeps himself politely at an emotional distance from everyone except Diesel. Coming into Charlie’s life about two years ago as a bedraggled kitten wandering the library parking lot, Diesel seems to have two particular affinities. He seems to understand the human language well beyond the sound of his own name or the phrase “Here, kitty kitty.” And he seems to sense and differentiate between human emotions, particularly sadness and anger, even when not verbally expressed. Weighing nearly 35 pounds and not yet fully grown, Diesel proudly sports a harness and leash and goes just about everywhere with Charlie. He openly seeks attention from everyone he meets but he gives back just as much or more after he “determines” the type of attention the human needs at the time. For all that we know about Diesel, we know very little about Charlie other than what I have already mentioned. The author never physically describes Charlie, not height or hair color, not weight or eye color, not anything. Since every other character is described as he or she enters the storyline, the absence of same for Charlie seems to be deliberate on the part of the author. Thus, each reader can visualize our main protagonist in whatever form fits or feels right at the time. While Charlie has eschewed emotional attachments since the nearly concurrent deaths of his wife and his favorite aunt, he rents out rooms to college students. As our story opens, one of the boarders, 18-year-old Justin Wardlaw, experiences three traumatic events in one day. First, he meets his previously unknown biological father for the first time. Secondly, the man he thought was his father strikes him in the face when he refuses to quit college and move back home. And, finally, he discovers the body of his biological father murdered in his hotel room. Godfrey Priest, the murdered man, is a best-selling author of violent thrillers that have a severely misogynistic overtone. A contemporary of Charlie, he grew up in Athena with a well-deserved reputation as a physical and emotional bully. Needless to say, there are many people in town with long memories and hardened hearts as far as Godfrey Priest is concerned, making no dearth of possible suspects. Miranda James does not portray Charlie as a suspect who must work to clear his own name. Nor does she portray him as one of those meddlesome types who feels he can do better than any police detective in existence. What she does is portray Justin as a good kid who has just been handed a very raw deal and is in dire need of help and adult support. Since Charlie is a well-respected research and archival librarian trained to find answers to oblique questions, he decides to lend those skills to Justin’s cause. And then there is the police detective, Kanesha Berry. Detective Berry is smart and intuitive but she has the people skills of a rock and the professional personality of the rattlesnake hidden under that rock. She is also the daughter of Charlie’s longtime housekeeper, Azalea. When Azalea asks Charlie to use his skills to help her daughter succeed in spite of herself, Charlie finds himself in the position of unofficial private investigator. James has written a solid first entry for her Cat in the Stacks series. The search for the murderer twists and turns as past deeds surface and motives multiply. Since the book is written from Charlie’s first-person POV, the reader knows no more than Charlie does at any time. And since the author writes the detective as a recalcitrant soul, fighting for control and against civilian assistance, the reader gets no help whatsoever from that quarter toward interpreting the information that Charlie gleans. Charlie makes mistakes, both intuitive and legal. Unlike what happens in many cozies, our protagonist immediately accepts responsibility, takes his lumps and makes a concerted effort to correct his behavior. And, unlike the progression in many cozies, he doesn’t figure out the murderer’s identity before the detective does. This novel has no obvious hook leading to another book. Nor does it end in a cliffhanger. But the murder of Godfrey Priest, and his investigation into it on Justin and Azalea’s behalf, changes Charlie. And on that point lies the premise of another book.

Surprisingly Deep and Heartfelt
Format: Paperback
At first, when i started this book, i didn’t quite know how to feel about it. It’s pretty slow in the beginning, about 30 percent is just them being “hateful” towards each other while actively not trying to acknowledge the obvious physical and emotional chemistry between them. The more and more i flipped the pages, the more i fell in love!! Ryan is the epitome of the best book boyfriend you could imagine. He’s patient, kind and thoughtful. Although, at times, i thought he and Josie both were too judgmental of each other and what the other enjoyed to spend their free time reading. So what, he reads romance? And so what, she doesn’t read romance? But as we get deeper into their story, we realize they each had their own reasons for having their opinions. This story was surprisingly very insightful, loving and deep. Not too deep to where you’re contemplating your life choices, but deep in the sense that you will be thinking about these characters and their abilities to over come trauma and presumptions about themselves and their careers. With that being said, i think that Ryans employees, specifically indira, were way too judgmental. They saw for themselves how Ryan also treated Josie, and he typically was more rude to her than she was to him. Especially being women, reading romance and working at a romance store, they should know how it feels for people to be prejudice about a Genre they enjoy, and should be mindful and have told Ryan to be kinder. That being said…at times Josie was, i will say, a prude. Especially in the scene where ryan had her read “beach read” by Emily Henry Aloud and she texted RJ and said that women and men dont have intimate moments like that IRL. She was almost disgusted at the idea of having good, respectful and yet “mind blowing” s3x. I thought it was childish of her, honestly. You’re 30. Grow up. Georgia, her sister, was also too almoy judgmental of Josie and her trauma growing up with their mother. Especially for someone who was becoming a psychiatrist. She didn’t seem to take into account the things she dint see growing up, because Josie spent her time shielding her and protecting her from all the chaos. Other than that, that was the only few times this book pissed me off. All in all i’d give it a 4.5 out of ten!

​If you are looking for a book with excellent banter, easy-to-love characters, and a romance that will completely charm you, put this one on your TBR immediately! 📚✨ ​Let’s talk about the character dynamics because they absolutely stole the show for me: ​🛡️ The FMC: Josie Klein wears an emotional suit of armor and is a little rough around the edges when it comes to letting people in. If you love Ali Hazelwood’s FMCs, you will fully understand and adore Josie. Watching her walls come down was everything. ​🐾 The MMC: Absolute GOLDEN RETRIEVER energy. He is a big softie with a heart of gold, but—and this is the crucial part—he isn’t afraid to put his foot down when it matters. The perfect balance. ​The banter between these two was top-tier, and the entire setting had me hooked from start to finish. It’s an absolute 10/10 for me!
