do88 Charge Pressure Pipe Kit BMW F Series B58 Gen 1

Compatible with M140i, M240i, 340i & 440i

Upgrade the performance and reliability of your BMW B58 engine with the do88 Pressure Pipe Kit — a complete charge pipe solution designed to replace the factory plastic pipework known for cracking under pressure. Precision-engineered in Sweden, this kit is ideal for tuned vehicles or those seeking a dependable, performance-ready upgrade.

Why Upgrade from OEM Pressure Pipes?

BMW’s factory pressure pipes are made from plastic — a material that’s cost-effective but not ideal for handling increased boost levels or the long-term heat cycles seen in high-performance engines. Over time, or when tuning is involved, these plastic pipes can rupture, causing boost leaks, limp mode, or leaving you stranded.

do88’s solution not only solves these durability issues but also improves airflow, reduces pressure drop, and fits perfectly without compromising the factory engine cover.

Why Choose do88?
