ECS Tuning Big Bore Cast Aluminum Turbo Inlet Pipe - B9 S4/S5 3.0TAll too often OEM components sacrifice performance in an effort to appeal to a wide variety of customers. While an enthusiast typically wants better boost response and more power, all while hearing the turbocharger breathe, a non enthusiast may give up these characteristics for a quieter ride.

All too often OEM components sacrifice performance in an effort to appeal to a wide variety of customers. While an enthusiast typically wants better boost response and more power, all while hearing the turbocharger breathe, a non-enthusiast may give up these characteristics for a quieter ride. Give your 3.0T Audi B9 S4 or S5 the performance it deserves and engage with your car for a more enjoyable driving experience! 

In the case of the factory turbo inlet pipe, mounted between the compressor housing and air intake hose, its purpose is to channel air from the inlet hose into the turbocharger inlet, all while reducing engine bay acoustics and sacrificing quality materials in favor of cheap molded plastic material. With the ECS Big Bore Turbo Inlet Pipe, the factory inlet pipe is removed and replaced with our straight-through, high flow cast aluminum inlet. This increases available airflow and turbocharger sound by creating a larger, smoother transition between the turbo inlet hose and compressor housing inlet. To top things off, the flange and bungs are TIG welded, machined billet aluminum to ensure longevity, strength, and dimensional accuracy.  

Key features: 

  • Cast aluminum construction

  • 55mm ID at the turbo inlet to maximize air flow (compared to stock 52.2mm) with an 11% increase in area

  • 66mm ID at the intake elbow

  • Retains factory PCV return and wire loom anchors

  • Machined billet flange and bungs for a precision fit and durability 

  • Oil resistant o-ring and stainless hardware included

 

Performance:

  • Increased bore diameter for increased flow and reduced restriction to the turbo

  • At -20 in Hg test pressure, the stock inlet has a flow rate of 327 CFM vs the ECS inlet which has a flow rate of 382 CFM, a 16.8% increase in flow rate over the stock plastic inlet!

Beautiful watch but flawed
Color: Gold Face/Gold Band, Color: Gold Face/Gold Band
This is a decent quality watch for the price. Been wearing daily for a few months now. It has maintained its color and been resistant to scratches. The sub dials are a fully functional timer/chronograph. Calendar is great addition. The band is good quality with tight fit. Mine came with a sizing tool which was awesome. Removed 3 links for a perfect fit. Not a big fan of the butterfly latch on the band as it can release when you bend your hand down, but for the look and price, I don't mind. Unfortunately, the other day, I took the family to Lake Tahoe where I slipped into the water at the shore. It was about a foot deep and soaked my clothes but no big deal. Shortly after I checked the time and saw water on the inside of the glass. I then noticed the reset button for the chronograph had fallen out. I thought it must have been from falling into the water though I couldn't understand how my wrist could have jarred the button out. When I got home, I found the button on the floor in front of the watch box that I keep it in. This means it just randomly fell out. It pushes back in but can be easily removed and the chronograph no longer works at all. The watch still runs but the water doesn't seem to want to dry out. Very disappointed as I really liked this watch. I wanted to contact Olevs about the 12 month quality warranty they claim on Amazon but couldn't find a way to contact them directly on Amazon. No contact info or links. The only options were product and seller feedback. Oh, and an address in China. Not much help. Glad to revise my review if the seller reaches out.

Stunning Automatic Watch With TopTier Durability and Precision
Color: Grey
“I got this Tissot PRX for my cousin’s birthday and bro fell in LOVE instantly. This thing keeps time like a beast, never slows down, never lags. Automatic movement, so no batteries, no drama. Durability? Stupid good. You can hit it, bump it, live life rough, it still looks box fresh. Size wise it was almost perfect. I just had to remove two links, nothing big. It’s light, functional, comfortable, doesn’t weigh you down, doesn’t get in the way but more importantly I can say this watch is in everyone’s eyesight when we wear it. Cause of course I had to get another one! Basically. I gave him a very nice piece as a gift, and now he’s walking around like he owns Switzerland.

Excellent value for an automatic watch, keeps VERY good time.
Color: Grey, Color: Grey
I've only had the watch for a day but wanted to leave a quick review on it to share a couple of notes. So far it keeps VERY good time, better than any of the automatics I own (including a Rolex Submariner, Tag Heuer Aquaracer, Tag Heuer Formula One, and several other sub $1k watches). I set it to an atomic time app on my phone yesterday and 24 hours later it's still SPOT on - hasn't gained/lost even a 1/10 of a second. I was shocked to see it's kept PERFECT time for the last day, I'm really blown away so far. I've worn it the entire time, we'll see how well it keeps time while being stored in a winder. This picture shown is the watch with a 22mm leather band on it, fit's without any issues (just need to squeeze in the leather a tad). I doubt it would work with a 22mm metal bracelet, but leather works great. Just FYI since the 21mm lug width is kind of odd. The face isn't quite a lustrious as the images make it look, but it's still a great-looking watch. For a sub $1000 automatic you can't go wrong, this is a fantastic watch at a great price. It'll be my daily driver for some time I'm sure. If I have any issues in the future I'll update the review.

It looks really cool and striking.

Really cool and beautiful watch. Although my specific unit runs 5 seconds fast every day—at first it’s annoying, but eventually you stop caring. 🤣
