987 air box with K&N air filter, 996 76mm TB and 997 Distribution T. I know this mod gave my 3.2L a 20 HP bump. This engine loves more air. Doing the mods yourself should be around $250 max. This makes a $200 Under Drive Pulley 5 HP look silly.

EDIT: Maybe $300 for the air intake upgrade. I forgot to add in some extra pieces you'll need and the silicone couplers.

Next on my list is headers, secondary cat delete pipes and Borla muffler.
