So I noticed at autozone (yeah i know i know) the other day they have these fittings by spectre to make your own intake. They also have a Y shaped adapter to add an extra air filter. The fittings come with a paper for the fittings you need for specific cars so its easy to do your own. Neways I decided to look into cars using two air filters (thinking it was crap) and found that some higher hp FI cars use it. Supposedly your insuring that your turbo/super gets all the air it needs.... what do you guys think, its a worth a try i suppose....
