You need a tune for tire pressure adjustments bro..

That investment is about to ruin your day without a speed density tune.
You need a tune with that.
Whats to blow off valve called?
Whats the filter for?
Very very nice sound! High quality and powerful Boxer Sound.
Don't follow this guy! Wow! No gasket, just install it anyway.
Geez, dude almost runs over his daughter. I wonder if he's ever heard of a car COVER??
You need a tune now
Fyi if you're not on speed density tuning with an atmospheric bov it can throw off at ratios since the maf is calculating for it. May get pops but less power eventually.
I miss my 04 STi. Had a HKS BOV too. You need to replace your stock horns with some Hellas next.
