Long Term On3 BMW N54 335i Single Turbo Review

on
It's been about three years since I've had the On3 BMW N54 single turbo kit installed on my E90 335i. Through those years, the price of N54 335i's has tanked quite a lot. So looking at a cost-effective kit such as the On3 N54 single turbo kit looks a bit tempting. Since most kits cost more than you paid for the car. I want to share my experience owning this kit for an extended time.   Read more

The main reasons are its easier maintenance, ease on your drivetrain, and a wider choice of turbos.   Read more

BMW E82 Battery Removed. Cant Open Trunk?!

on
Sometimes I wonder why BMW does certain things. In this instance, why did they choose to remove the key lock mechanism in the trunk of cars starting in MY2009? I recently had to change the battery on my E82 MY2011 BMW 128i, in which I removed the old battery from the car so I can use it as a core. Then closed the trunk and locked the car by using the key in the driver's side door.    Read more
