135I GETS BIG ARM INTERCOOLER AND HOSE UPGRADE! 500HP

So I'm showing you how to basically install the 7 inch ARM intercooler on a BMW 135i with a n54 engine. It is a long process however it can be done in a few hours. I install the intercooler hose upgrade, the 7 inch intercooler and a new aluminum charge pipe. Really love the ARM products and I hope you do as well they are a more affordable and about the same quality as other n54 bolt on brands.
