The factory BMW charge pipes are prone to cracking, as they are made from brittle plastic. Here at Turner, we sell several brands of replacement charge pipes that are typically made from cast aluminum. We recommend upgrading to hard charge pipes even on stock forced induction vehicles to avoid cracking - we've seen cracking occur on high mileage cars running stock power just as frequently as we do with high horsepower builds.
The do88 Performance Charge Pipe System replaces the fragile factory unit with a robust, cast aluminum Y-pipe and a mandrel-bent rear turbo charge pipe. Engineered to withstand extreme thermal and mechanical stress, this direct-fit upgrade increases airflow by 15% over stock. Bench testing demonstrates a massive flow rate of 960 CFM at 150mbar (2.17 psi), compared to the restrictive OEM baseline of 835 CFM. This reduction in backpressure significantly optimizes airflow transitions and maximizes power potential.
