do88 Charge Pipes Turbo-to-Intercooler – BMW M3 / M4 / M2 Competition (F8x, S55)

OVERVIEW

The S55's plastic pipes from the turbos to the intercooler are known to crack and split at the turbo connections, especially once boost goes up. The do88 TR-240-SS replaces them with full-aluminum 2.25" (57 mm) mandrel-bent pipes with CNC-machined turbo flanges.

They were designed from a 3D scan of an M3 Competition engine bay to keep smooth bends and the factory engine cover fit, and flow up to 4 percent better than stock. Reinforced silicone couplers connect them to the intercooler, and longer OE-style lock pins are included so the engine cover grommets still snap on.
