Upgrade your engine with the do88 charge pipe kit for B58 Gen 2 found in Toyota Supra A90 and BMW Z4 M40i!

The B58 Gen 2 engine is fantastic but it has a known reliability issue: its charge pipe. This pipe is known to be fragile and can break even on stock cars during track sessions. If you're considering tuning your engine, it's highly recommended to upgrade the charge pipe beforehand.

Many aftermarket charge pipe kits for the B58 engine are available, but in our opinion, most are not properly designed. Many competitors use a basic design: two pipes joined by a straight reducing silicone hose. It's evident they haven't understood the importance of handling the thermal movement in this system. Such design is almost certain to cause problems with the hose popping off due to it does not allow movement from temperature changes. A common solution people think of is tightening the clamps more, but this will in most cases break the pipes since it will deform the clamping surface.

But we've taken a different approach at do88. For us it was clear the system needs a flexible connection in-between the two pipes which can handle the thermal expansion / contractions. Our solution is an aramid reinforced silicone hose with 3-humps. This hose design allow movement in any direction without folding or putting the connections at stress. To further strengthen our design the pipes have CNC-machined 6063 hose connection ends with 3mm wall thickness. These hose connections won’t deform even for overtightened hose clamps.

Our charge pipes don’t only solve the durability but of course also improve the performance. We designed our pipes with a larger diameter and smooth mandrel bends to enhance the performance. The lower pipe measures 60mm (2 3/8”;) and the upper pipe 76mm (3”;), they effectively reduce the pressure drop and cut down on turbulence.

Our charge pipe, which connects to the throttle body by its CNC machined flange, has two 1/8 NPT ports suitable for methanol injection or outlets like a boost pressure sensor. Additionally, we provide two 1/8 NPT plugs for those who choose not to use these ports.

Features:

  • Flexible hose connection in-between upper and lower charge pipes allowing movement which prevent the hose from popping off.
  • Special designed 3-humped reduced silicone hose reinforced with high temperature rated aramid fabric and outer stainless-steel rings.
  • Super high quality hose clamps from Mikalor included. These clamps are fitted with an inner-ring inside the clamp that prevents damage to the hose as well as distributing the pressure of the clamp evenly around the hose.
  • Better air flow and less backpressure for your engine!
  • 27 % more flow than OEM, with 558 CFM @ 150mbar (2.17psi) compared to the OEM 439 CFM.
  • CNC machined hose connections with matching inner diameter to the pipe that gives a deformation safe hose clamping surface.
  • CNC machined MAP sensor boss, turbo and throttle body connections.
  • CNC-machined (2x) 1/8 NPT connections, perfect for methanol injection or as outlets for example boost pressure sensor.
  • Two 1/8 NPT plugs are included if you don't use the ports.
  • Mandrel-bent 60mm (2 3/8”;) and 76mm (3”;) charge pipes coated in a stylish black powder coat.
  • Does not interfere with the engine cover.
  • Includes all hardware and instructions for complete installation

BEST PILLOWS EVER!!!
Color: White-cooling Basic, Size: Queen(Pack of 2)
I am very picky with my pillows because I have a bad neck and I can never seem to find a good pillow. But I tried this pillow because it had everything I was looking for and the price was great! You get two of them and they are absolutely awesome.! normally I would need to lay on two pillows to try and get comfortable but with these pillows I just lay on one and I wake up with no neck pain. They really have a nice cooling effect. They actually puff up immediately after opening them. All you have to do is just shake them up and the pillow just puffs straight up.. It comes with extra cushioning if you want it to make it firmer and if you don’t want it as firm as it is, you can actually take some out. It really is such a beautiful pillow. It’s perfect in every way to me being such a picky pillow person. You just lay your head down on it and it forms around your neck and your head and when you get up, it goes right back to its normal form. It doesn’t get flat and I love it. I completely recommend this to anyone who is a person who has a hard time finding a really good pillow.

Top of the line, best pillows Ive ever had
Color: White-cooling Basic, Size: Queen(Pack of 2)
These pillows are top of the line! I bought them in 2024 and they are still fluffy. When they lose a little fluff, you just punch em around a little bit and voila, like new again. They have kept their shape cery well and do great for cooling. I haven't had to add more filling yet either. I just laid my head on one and thought, I need to do a review cause everytime i lay on these pillows its like clouds. My head is heavy and this is relief :-D

Weird smell
Color: White-cooling Basic, Size: Queen(Pack of 2)
The pillows are great for someone looking for something cool and comfortable. We loved them so much that we bought a second pair. However, we were seriously disappointed with the odor of our last purchase. They give off a strong and indescribable chemical/burning plastic smell so nauseating that it’s difficult to sleep with. We’re hoping this issue will resolve with a couple more washes of the pillow cases, but am worried the source is the stuffing itself.

helped treat my sore neck
Color: White-cooling Basic, Size: Camping Pillow(Pack of 1)
This pillow — after dialing in the right amount of shredded foam — has greatly helped my sore neck. Initially, I had to remove some foam. Then I gradually added foam until it reached optimum comfort and support. It is also CPAP-friendly — especially when I position my head near the pillow's edge. (I am a left-side sleeper.) I like the travel size because I use a bulky hugging pillow to ease stress on my shoulder and elbow. That makes my side of the bed feel cramped if using a larger head pillow. A smaller pillow is easy to flip end-to-end in the middle of the night. I have spent lots of money on pillows over the years, but this is the best I've ever had for relieving [1] neck pain and [2] CPAP mask seal problems. Very comfortable, supportive, and affordable. I did not notice any unpleasant smell — and I am usually sensitive to that kind of thing. Would highly recommend.

Love them!
Color: White-cooling Basic, Size: Queen(Pack of 2)
Love them! After 10 years with our MyPillows, they finally lost their fluff. The reviews I read of the MyPillows of today were not good; they didn’t have as much filling as they used to. These pillows remind me of how fluffy our new MyPillows were 10 years ago!! You sink right into them and can mush them however and they stay. These are way cheaper than the Coop and it’s the same concept; add or remove the filling as needed. The cooling side is a huge plus too! You won’t be disappointed with these pillows!
