OEM fit and finish.

My old bypass valve was crusty and leaking. The vacuum leak this created made the car idle poorly and it was difficult to tune. Luckily, ZZP had just what I needed. It took 15 minutes to install and now the car runs right. If you already have the supercharger off for any reason, do yourself a favor and just replace this part while its off. It'll keep your M62 powered car happy and it'll keep you from stalling the car at random stop signs.

Great part at excellent price

Had to replace mine when a port snapped off. Fast shipment at an awesome price. Seriously if you look around for the oem part its gling to run you an extra $100 minimum. This part went on easy and works great.

Works fantastic

This wasnt the part i needed to fix my check engine light however after replacing the old one with this one. I did discover i had a small boost leak in the old one. Went in easy 2 min replacement.

Works like it should

Experience was great. Fast shipping and good price.

Great parts as always

Great parts as always. Went ahead and replaced the bypass valve while I had the blower off for ease of mind.
