do88 performance J-Pipe Upgrade (Cold Side) is designed for an easy drop-in-fitment in your BMW F8X M2C/M3/M4.
The S55 twin-turbo engine that powers the BMW F8X M2C/M3/M4. is equipped with plastic intercooler pipes on both the hot and cold side. These pipes are a week link on any tuned car or in some cases even on a stock tune. The OE plastic pipes often crack / split leaving you with a boost leak. With our performance intercooler J-pipe, we like to offer a solution for the reliability issue and of course at the same time minimize the restrictions by improving the air flow!
To get an exact 3D-model of the available space to design our intercooler pipe in we did 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 is 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 also have confirmed in 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 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 "fishbone" plastic retaining clip.
Significant advantages with do88 performance J-Pipe Upgrade:
- Improved reliability
- 6061 Aluminum instead of plastic
