The best BMW 135/335 E9x/E8x N54 performance intercooler and pipe kit on the market!

This comprehensive package includes both our do88 performance intercooler and charge pipe kit, delivering unmatched performance and reliability. If you have high horsepower goals and demand the absolute best, this kit is tailored for you.

By upgrading to our performance intercooler alone, you'll experience a significant improvement. However, when combined with our charge pipe kit, the enhancement is even more substantial. Our pressure pipes offer considerably better airflow compared to stock piping, ensuring improved reliability over time. Even on a non-modified car, the stock plastic pipe is prone to breakdown, making our kit a crucial upgrade.

• Greater core volume: 15517 cm3 (6933 cm3), an impressive 124 % larger!
• Larger frontal cooling area , 1151 cm2 vs 658 cm2, a remarkable 75 % larger!
• Air flow at 0,15bar/2,18psi pressure drop: 498 CFM (354 CFM), a significant 41 % higher!
• Peak power gain of 13 hp! Measured on 335xi N55 with Stage 1 tune.

The BigPack includes the do88 full aluminium performance intercooler and a complete 3” (76mm) throttle body side charge pipe kit and silicone hoses. This BigPack replaces everything from the intercooler inlet to the throttle body, hence the drastic improvement in airflow and cooling performance.

The do88 performance intercooler is an all-aluminium construction. With CAD-designed, flow optimised cast end tanks along with an optimised core design, it achieves the best possible cooling efficiency combined with lowest possible pressure drop!

The charge pipes are manufactured in 3” mandrel bent seamless aluminium pipes with CNC machined throttle body flange. Custom made high quality silicone hoses with 4 layers of polyester/aramid reinforcement. These hoses can handle very high temperature and pressure!
It's important to note that the OE intercooler and pipes were designed for the power level the car was originally built for. Any power increase or intense use of the vehicle, even in its stock version, may exceed the performance capabilities of the OE parts. Already after an engine software tune, the do88 BigPack will truly unlock the performance potential you desire.

Rest assured, the do88 BigPack comes with all the necessary hardware for a hassle-free installation, ensuring a seamless upgrade experience.

Please take care of your engine. Choose DO88 every time!
