Upgraded my full kit and installation was pretty easy. Only issue is that it appears the shim for the bypass valve isn’t the correct length and when boost passes 20psi there’s a squealing sound coming from the factory bypass valve that can only be described as when you blow up a balloon and pull the sides next to where to blow it up and let the air out. The parts are great quality as always, and if it wasn’t for this weird air squealing noise I’d give it 5 stars. Also, the ZZP BOV is loud but it’s more of a woosh sound than other bov’s out there.

It was good
Good quality and good shipping
Great quality love it thanks
Never have i ever
Never have i ever had such a great experience with a vendor. I have to say that zzp has met an exceeded my expectations on everything I have purchased. The intercooler kit was impeccable quality, easy to install, and made a great difference in power. Thank you zzp for another kick *** experience.
The quality of this product is great. MUCH better than the factory plastic one with thin core. Much beefier and cooler temps. Overall the install was straight forward and simple. The lower pipe can be a challenge but I found that removing the radiator and fan on my automatic HHR SS made it much easier to do and the GMS1 kit fit great. The MAF block off plate needed to be modified a little using a rat tail file to open one of the bolt holes up some as most seem to complain about. It's an easy fix but definitely something ZZP needs to address as it seems to have been a problem for a long time now... I will still give it 5 stars since the fix was quick and took an extra 5 minutes and didn't hurt the overall performance of the part.
