Well, Fedex came pretty late last night.
I was able to sort of install it while holding my iPhone as a flashlight. Since I was working in the dark, some instructions could have been useful. I couldn't see where that arm was to be mounted in the dark. Other than that, the coupler was a bit of a pain in the ass to wiggle on, and it needs to go on the right way for everything to mount up. It can go on both ways and get the intake on, but it just dangles around in the engine bay then.
I removed the engine cover first. Then I removed the OEM intake by unscrewing the clamp thats up by the cowl. Then I took the 4 screws holding the top of the airbox down. After unplugging the MAF and that line on the intake with the green clip. the whole piece came off. The lower intake box that has the filter just wiggled out for me. The previous owner had an Ingen intake, so Im not sure if he forgot to put screws back in or what.
The silicone coupler that is provided needs to go with the shorter end of the elbow on the rest of the OEM intake that connects to the turbo. I did this the wrong way in the dark, and the arm that mounts to the engine could not line up because of this. I put the filter and MAF sensor on the stainless pipe, then wiggled it into the engine bay. You will see the mounting point when you put it in, theres a few hoses/lines around it so its a bit hard to get the 10mm wrench on it. I was able to get it off with a ratcheting wrench, and had very little room to move a ratchet wit no extension.
Also, you need a t20 torx to get the original MAF sensor off. The bolts on the new one I think were a 3mm hex head.
My only concern is the line that connects to the line on the intake that is clipped on with the little green clip. Not sure if its because it was taken on and off a few times by the previous owner and me a couple times while getting the intake on, but even with the clip on you can slide it off. I think it just cant grip the stainless steel as tight as it could the OEM plastic. I may put some electrical tape on the nipple so the clip has something to push into and then tape it down for extra security. I did a few 2nd and 3rd gear WOT runs and it didn't come off yet.
It sounds great. Partial throttle you hear the spool quite a bit. With the windows up and heavier throttle, the sound symposer drowns out the intake a little (going to delete that soon). I didn't notice any power differences with this compared to the drop in filter I already had with my Access Port. Its also like 60*F out now, so cant comment on head issues.
