Ram Air Your Celica (sort of):
FYI: This can only be done with the 2003 celica because of the new nose style.
behind the nose grill on the drivers side (air box side) there is a foam pad, this blocks the air box from getting fresh air punched right into it.
I took out the air box and cut out the pad with a utility knife, now air goes straight into the box. with this and my TRD Air Filter
I have noticed a big difference over the stock set up.
