do88 BMW 135I / 335I N54 (E8X/E9X) Chargepipe

The best BMW 135i/335i N54 performance intercooler pipe kit on the market for those with significant horsepower goals wanting to upgrade to the absolute best. do88's pressure pipe delivers considerably better airflow than the stock pipe, verified in both in-car testing and on their own SuperFlow SF-1020 flow bench.

The numbers: 36% higher airflow at 0.1 bar/1.45psi pressure drop (737 CFM versus 542 CFM stock). Manufactured from 3in mandrel-bent seamless aluminium tubing with a CNC-machined sensor flange for the best possible fitment, paired with custom high-quality silicone hose reinforced with 4 layers of polyester/aramid fabric, built to handle very high temperature and pressure. Two 1/8-27 NPT methanol injection connections are included, supplied with blanking plugs if not in use.

Please note: the OEM intercooler pipes and hoses were designed for the power level the car was originally built for, and a power increase or even hard use in stock form may exceed what the OEM parts can handle. Only after an engine software tune will do88's pressure pipe give a genuine performance increase over the OEM version, on a fully stock car this is primarily a durability and reliability upgrade.
