BigPack BMW 135i 335i 35i N55 2010-2013 (E9X E8X)

The best BMW 135/335 E9x/E8x N55 performance intercooler and pipe kit on the market!
This comprehensive package includes both our do88 performance intercooler, charge pipe kit and turbo outlet hose, 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 and turbo outlet hose, 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.

Advantages with do88 BigPack (OE intercooler/pipes):
– 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 powergain of 13 hp! Measured on 335xi N55 with Stage 1 tune.
– Lower post intercooler air temperature at same conditions: 43°C (58°C), a substantial 15°C lower! Measured on 335xi N55 all stock except the intercooler.
– Designed to handle high pressure and temperatures!

This BigPack replaces everything from the turbocharger outlet to the throttle body, hence the drastical improvement in airflow and cooling performance.

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

Our upgrade turbo outlet hose included in this kit is designed with precision and the highest quality materials, ensuring long-lasting durability and optimal functionality. The CNC machined turbo outlet adapter provide a perfect fit, while the high quality silicone hose reinforced with 4 layers of high temperature aramid fiber fabric guarantees maximum strength and flexibility.

The charge pipes are manufactured in 3″; mandrel bent seamless aluminum pipes with CNC machined throttle bodu 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.
