Upgrade your engine with the do88 charge pipe kit for B58 Gen 2 found in BMW M340i and more!
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.
do88 have taken a different approach. For them it was clear the system needs a flexible connection in-between the two pipes which can handle the thermal expansion / contractions. Their 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 the 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.
do88 charge pipes don’t only solve the durability but of course also improve the performance. They designed their 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.
do88 charge pipes connect 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, they provide two 1/8 NPT plugs for those who choose not to use these ports.
Important Notice
The space available for the charge pipe between the throttle body and the slam panel (the sheet metal part located over the radiators) is very limited on the G-chassis platform. In some cases, it may be necessary to grind the edge of this slam panel by a few millimeters to provide additional space for the do88 charge pipe.
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
