DO88 Chargecooler Pipes (BMW F8X M2C / M3 / M4)

By DO88

do88 performance turbo to intercooler pipes designed for an easy drop-in-fitment in your BMW M2C / M3 / M4 F8X.

The S55 twin-turbo engine that powers the BMW M2C / M3 / M4 F8X is equipped with plastic intercooler pipes. 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 at the turbo connections leaving you with a boost leak.

With our performance intercooler pipes 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 pipes in we did a detailed 3D-scan of our M3 Competition engine bay. With the help of this 3D-scan model we could design new 2,25” (57mm) intercooler pipes with smooth routing.
Squeezing in as large pipes as 2,25” (57mm) is a challenge since it is not that much clearance between the engine cover and valve cover. Many after-market intercooler pipes make it impossible to snap the engine cover rubber grommets correctly onto its lock pins. We have solved this issue by our design of this pipe and that we include longer OE-style locking pipes for the engine cover.
We decided to not include methanol injector connections on our intercooler pipes since in our opinion it is better to have this after the intercooler. Our intercooler-throttle body (J-pipe) has 2 methanol injector connections.

Our final design is a full aluminum construction with mandrel bent pipes and CNC machined turbo flanges. We also include more durable silicone hoses that connects our pipes to the intercooler inlet flanges. For a cool stealthy look we include matte black hose clamps.

Significant advantages with do88 performance intercooler pipes:

- Improved reliability!
- Up to 4% better air flow!
- Matte black silicone couplers included!
- Maintained engine cover fit.
