2011 Evo X GSR

[Ken]

Okay, so i decided this weekend to tackle the intake. As mentioned before there is some arguments about whether or not you should be tuned for an intake. From what i read intakes cause the car to run a little leaner but considering that, like the ralliart, the car runs obnoxiously rich from stock (the ralliart as some can attest from 33W drives, would spit out black smoke if i punched it, this car does the same), it wouldn't be an issue.

Took all of about 15 minutes to disassemble the stock airbox; hardest part was actually trying to get those damn plastic screws Mitsubishi is so fond of off. Finally i figured out that by undoing the bolts connecting the MAF housing to the back of airbox i can remove the filter and the back end will come out. I also disconnected the ground to the battery, as i read that the people who had done so swore it ran smoother that why. I figured it couldn't hurt either way so i just did it.

So i attached the cone filter I had, reattached the battery and started her up. No issues at idle and first drives have gone well. Obviously you can hear the difference and the butt dyno tells me that it pulls a hair harder in the upper RPMs. The Cobb intake linked to before claims an additional 21HP and 24TQ with theirs, and as you can see below mine is fairly similar. Obviously those numbers are marketing claims, but still it's something i suppose.

My intake, sorry for the crap quality.

I decided to retain the stock air intake snorkel and front half of the stock airbox to try and bring in some air straight to the filter. Not sure how much it actually will do but i know a bunch of the aftermarket intakes do retain it.

Plan from here is this weekend to try and tackle some form of a heat shield to prevent the A/C fan from blow air onto the filter in the summer. Open to any suggestions on how to do so.
