Impreza WRX STi Custom short ram intake heat shield (clears Process West FMIC piping)

Intake manifold temperatures improved drastically:
95-99F @ 40+ mph | 109-116F @ <40 mph / img_0613
Intake Manifold Temperature: -[12-15]F cooler at speeds >=40mph | -[35-40]F cooler at speeds <40mph(including idle)
Temperatures measured w/ Greddy Informeter and are compared to short ram w/o heat shield.
Outside temperature according to STI cluster was 89F.
I'm also using the GP Moto intake snorkus delete elbow to help direct more air to the intake.






Click here for photos of the whole process

I know people say a cold air intake is best, but there's hardly any air flow in the fender because of the fog light.

Please also note that because my hood has extra vents(shown in photo below) on the sides, cool air flows directly into the custom intake heat shield box.


I'll be replacing the air filter in the photos with a foam filter and using Cobb Street Tuner to tune it once installed.

Here are mor photos of the complete car

Yep, a lot less lag. And the performance means more to me than the looks.

I only wish I would have taken intake manifold temperature readings while the APS 525 FMIC was installed w/ the APS cold air intake so I could compare the readings. If anyone reading this has intake manifold temperature readings please post them or PM me. Thank you.

Sheet metal, weather stripping vinyl, rivets, silicone(for the cracks) and high temp(also helps block heat) ceramic coating.

Is this the '04 STi with the bugeye conversion I saw on an earlier thread? Nice work on the heat shield! I wonder though if K&N will sell their heat shields seperatly from the Typhoon intake for the guys who can't fab their own stuff.

Yep it's the 04 STI that I converted into a bugeye. The K&N shield is too wide to fit because of the Process West FMIC piping and its hole for the intake is too low(intake sits much higher because of FMIC piping). Custom fab' is the only way to go in some cases.

i was trying to make a custon shield as well, but wanted to use a material similar to the ones used by K&N or spt, but the sheet metal should be good enough.
