Review on Enhance Performance: Air Intake Turbo Charge Hard Pipe Kit with 50mm BOV Replacement for BMW N54 E88 E90 E92 135i 335i 335 by Joseph Reed

What a waste of time! I was upset and brought this junk back asap without hesitation! BMW 335i.1 2008 - Injection pipe at the connection to the throttle valve too long. It does not slip and therefore cannot be mounted. 2 - The back of the injector tube is angled to fit over the power steering hoses on the engine fender. That's bad too. So these 2 problems prevented me from going further. I know there will be more problems after 2.3 - even if it slips on the throttle body there is a real potential problem with the throttle body or intake manifold breaking. The back of the tube sits on top of the power steering hose that sits on top of the motor wing chassis. The engine should "flex" when accelerating or cornering/accelerating/braking. Over time, the blowpipe interferes with the bend, breaking weak points in the chain when the pipe hits the engine bay fender where the horsepower hoses sit. The stock blowpipe is spaced more than 1 inch from the engine blade and is designed not to interfere with engine flex. So if you need to install it, consider previous buyers to just have it installed. It may not be obvious, but the flex gap engine is important, it cannot properly mimic it.
