Upgrade your stock BMW N55 charge pipe to the MAD N55 charge pipe for superior airflow, unmatched reliability, and enhanced performance. Made from high-quality aluminum, this charge pipe is built to last and provides a significant improvement over the stock plastic version.
Unlike the stock charge pipe, which is prone to failure, the MAD N55 charge pipe is designed to withstand the demands of high-performance driving. With its robust construction, you can trust that this charge pipe will deliver optimal airflow and ensure consistent performance without any risk of failure.
The MAD charge pipe is engineered to fit seamlessly into your BMW F1x 535, 640, X5, or X6. It retains the BMW C-clip and O-ring for the best fitment possible, ensuring a secure and leak-free connection. When installing the MAD charge pipe, make sure to transfer these components from your stock charge pipe to the MAD option.
One of the standout features of the MAD N55 charge pipe is its two meth bungs, both of which come pre-sealed. If you're not planning to use methanol injection, simply keep these bungs closed, and they won't interfere with the performance of your BMW.
When you choose the MAD N55 charge pipe, you'll also enjoy additional benefits. The charge pipe comes with a lifetime warranty on defects and fitment, giving you peace of mind and confidence in your purchase.
