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 Mishimoto G8X M3/M4 performance charge pipe replaces the stock rubber and plastic with robust silicone and cast aluminum for a charge pipe that's stronger and 27% less restrictive than stock. Our charge pipe retains the flexibility of the stock front section but replaces the stock rubber hoses with durable silicone for greater heat and pressure tolerance. The plastic merge has been replaced with cast aluminum for a significant durability upgrade, while the transitions have been smoothed to allow improved flow to support future performance upgrades. This performance charge pipe is a direct fit for your 2021+ BMW G8X M3/M4 and is backed by our Mishimoto Lifetime Warranty for a lifetime of letting your legend breathe free. So, if you're ready to unleash the limitless potential of your M3 or M4, this Mishimoto performance charge pipe is for you.

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.
