Product Info

Looking to maintain the power on your BMW 135i and 335i?

Install the Active Autowerke BMW 135i 335i intercooler sport version for nearly factory-like fitment and experience the meaning of sustainable BMW power in a compact package. The factory intercooler maybe adequate for the stock power, but with raised boost comes more heat to dissipate. To overcome this...a larger intercooler is the answer.

The total area of our new core is much larger than the factory counterpart. Dyno testing revealed a temperature drop of close to 30 degrees Fahrenheit less in the intake manifold air temperature and close to 10 more usable rear wheel HP on our Mustang MD250 dynamometer. The ambient air temperature in our shop measured 92 degrees F during the test.

The Active Autowerke BMW 135i, 335i intercooler is the best performing bolt-on performance intercooler that you can buy. Simply by bolting on this intercooler on a stock car, you can expect over 10 wheel horsepower gains due to the revised efficiency, or even more with additional performance modifications like our Active Autowerke BMW 135i Downpipe. This intercooler is created to handle more internal air flows than its stock counterpart, and will not heat soak as readily like the BMW factory unit.

BMW 135i 335i Intercooler Benefits And Design For Performance

Designed from inception, this BMW 135i, 335i intercooler has the largest swept area that could possibly be fitted within the narrow space confines that the BMW factory allowed. Simply put, this BMW intercooler will perform and deliver consistent, reliable power run after run without power robbing heat soak.
Some minor cutting is required. This Active Autowerke BMW intercooler features the industry standard of a bar and plate core design with seamless cast end tanks with 2.25" inlet and outlets for the least amount of air restrictions possible.
Proper placement of heavy duty mounting tabs ensure for a good fitment. Included in each intercooler kit is all the piping necessary with heavy duty silicone hoses and clamps all for a smooth, trouble free installation.
Designed specifically for the BMW E8X 135i and E9X 335i in 2 door and 4 door configurations. Just specify your particular model and the kit will be built to include all the necessary hardware for your specific application at no additional cost to you.
