Review on High Performance K&N Cold Air Intake Kit: Guaranteed Horsepower Increase for 2004-2008 Acura TL, 3.2L V6, 69-0021TB by Trevor Rodke

I installed this in my 2004 TL 6-SPD (SOHC V6 VTEC). Made in the USA; quality construction and paintwork. The two brackets make the sanitary ware beautiful and durable. Installation is easy except removing the factory resonator; You have to sniff it out. The intake noise has changed; At lower RPM the OEM sounds better (domesticated) but at higher RPM it sounds good. Responsiveness is also slightly improved. I haven't checked the increased fuel consumption yet. A note: be sure to install a drycharger (something like a bag for storing nuts and bolts) over the filter element, which will keep water out but is not waterproof.
