Review on ATP Automotive Graywerks 106001 Engine Intake Manifold: High-Performance Product for Enhanced Engine Efficiency by Tory Richardson

The air intake seems to be of decent quality but some parts don't fit properly. When installing a new gasketed intake manifold, the gasket appears to fit, but when installed on the lower intake, the holes do not line up properly. The intake manifold needs to be moved slightly to fit the bolts. I didn't believe it, so I bought a MAHLE seal and it fit perfectly. No movement is required to align the screw holes. Also, the o-rings are only for the top of the fuel injector. You will need to buy different o-rings for the bottom of the injector if you want to replace them, which I highly recommend. Overall I am very disappointed with the product. I had high hopes for this and it didn't work out the way it was supposed to. If I were to do it again I would spend the extra money and go for the GM version. A lesser skilled mechanic or DIY enthusiast may encounter leaks and other problems when attempting to use many of the supplied parts.
