DO88 performance intercooler to throttle body J-pipe designed for an easy drop-in-fitment in your BMW M2 / M3 / M4 F8X

The S55 twin-turbo engine that powers the BMW M2C / M3 / M4 F8X is equipped with plastic intercooler pipes on both the hot and the cold side. These pipes are a weak link on any tuned car and in some cases even on a standard tune. The OE plastic pipes often crack / split leaving you with a boost leak.

With our performance intercooler J-pipe, we offer a solution for the reliability issue and of course at the same time minimise the restrictions in the standard pipe by improving the air flow!

To get an exact 3D-model of the available space to design our intercooler pipe, we carried out a detailed 3D-scan of our M3 Competition engine bay. With the help of this 3D-scan model we could design a new 3,5” (89mm) casting J-pipe with nice smooth routing. Most aftermarket J-pipes on the market are made of mandrel bent 3” pipes cut and welded in several pieces to achieve the J-shape. The OE J-pipe is 3,3” (85mm) so it is clear a 3” version is not ideal in terms of airflow, which we also have confirmed on our Superflow flow bench.

Our final design is a super durable 3,5” (89mm) casting J-pipe which improves the airflow. It has a free form shape with the same diameter all the way to the throttle body which is “impossible” to achieve with mandrel bent pipe. Our J-pipe has two methanol injection connection (1/8 -27 NPT) which is blanked off with plugs at delivery. A more durable silicone hose is also included together with matte black hose clamps for a clean stealthy look. A new C-clip is included to fasten the J-pipe to the throttle body instead of the flimsy OE plastic retaining clip.

Significant advantages with do88 performance intercooler J-pipe:

• Improved reliability!
• 6061 Aluminum instead of plastic
• Stainless steel throttle body C-clip
• Matt black silicone hose coupler included
• Up to X% better air flow!
• 2x 1/8-27 NPT connections that can be used for methanol/nitrous injection or as vacuum port fitting for pressure gauge. Blanking plugs are included!
