I now have the dash dyno spd and can read my iat temp. I was wanting to find out if it was cooler with just the tube and filter, or cooler with wrap around the tube or box around filter, etc. I want to get my air temp as cool as possible for drag racing. Would it be more controlled setting still , or going down the highway? or would I be better off testing this at the track? (kinda expensive, and screws with dial in)
