Now that the Downpipe install is complete I have moved onto the Group N inlet install.

First off, I have installed turbo inlets on 2 other turbo Subarus before, and this was the most challenging. I had to cut off all the vacuum ports on the OEM inlet to get that thing out. Not to mention Subaru placed the damn BPV return hose clamp in a place you just cant get to! Anyway after an hour of pure will I removed it from the car.

Comparison of the Stock Inlet vs the Group N Inlet

The Group N inlet install literally took 1 minute. This was by far the easiest inlet I have ever installed. It fits dead nuts with nothing rubbing or interference. It slid perfectly onto the turbo with no hassle.

However, my BPV return hose is being pinched by the throttle body a bit more than I would like. My inlet didnt come with a fitting to connect the BPV hose, and the one I am using is a bit longer I think. I will work on making the line fit better tonight.
