Following the instructions make the installation so much easier. One bit I did have trouble with was screwing in the heat shield. In the instructions there were 2 holes connected to 2 rubber donut gaskets, but I could only use 1 as the other hole was blocked off. This may have been due to changes between the years (I drive a '09 WRX). Overall, really great product with easy installation. Love the sound of the intake in the higher RPM range as I can hear my factory BPV. Wish there was a lower end sound, but I guess no sound below 2500RPM is ideal for daily driving.
