do88 Charge Pipe with Silicone Hose – BMW M2 / M235i / 335i / 435i (F-Series N55)

OVERVIEW

The plastic charge pipe between the intercooler and throttle body on the N55 F-series is one of the first parts to fail once boost goes up. The do88 TR-190S replaces it with a 3" mandrel-bent seamless aluminum pipe and a reinforced silicone hose, built for owners chasing serious power.

do88 measured 680 CFM against 460 CFM for the factory pipe at the same pressure drop — 48 percent more — verified on their SuperFlow SF-1020 flow bench and in the car. The sensor flange is CNC-machined, and two 1/8-27 NPT ports are ready for methanol injection, with blanking plugs supplied. do88 notes the gain over OE only shows once the engine is tuned.

TECH RESOURCES

• Required extras: none — all installation hardware is included. A tune is needed to see a gain: Bootmod3 Tune – BMW N55 (F-Chassis), MHD Super License – BMW N55 (F-Series) or Burger Motorsports JB4 – BMW N55 (F-Chassis).
• Installation instructions (do88): TR-190S N55 F-series charge pipe installation instructions (PDF)
• Installation notes: remove the engine cover and OE charge pipe, transfer the boost/temperature sensor to the do88 flange, fit the hose adapter at the intercooler and secure the pipe with the supplied hardware. Leave the methanol ports plugged unless you're running injection.
