Sorry guys I've researched as much as I could before starting a thread. I have an 06 wrx w/ an ebay aftermarket intercooler. The stock hood scoop has a rubber lining underneath it I guess to keep it air tight at stock. The problem is that now with the intercooler is that rubber lining of the hood scoop is rubbing and mainly squeaking against the intercooler. It also is constricting the air flow to only reach about 60% of the intercooler because the lining cuts off the rest. Is it safe to cut this lining off now? There is also like a exhaust capsule to the left on the hood scoop about 4 inches wide. Is it safe to gut everything off the hood scoop to allow max air flow and stop this squeaking sound?
The sqeak you are hearing isn't from the rubber piece, it's from 3 plastic clips that hold the windshield wiper hose. Just remove the rubber piece under the hoodscoop (its ok to do this) and remove the plastic clips, cut the hose a little to give it a tighter fit so it doesnt hang and your good to go.
They also make aftermarket airsplitters for larger TMIC.The rubber skirt is not for sheilding water,its to seal the top part of the TMIC from the engine bay and for the air to get forced through the intercooler.
All of this sounds good I will have to look under the hood later. What about that portion of the hood scoop on the left side where it looks like its almost a vent. Its about 4 inches long and it doesn't look like air is able to get to the intercooler.
