Not sure which 2009 Acura TSX Air Intake Systems are right for you? We have over 20796 customer reviews, with an average rating of 4.5, to help you find exactly what you're looking for. Here's what some of our customers have said:

"Intake it great, installed in an hour and made a world of difference. Throttle response is only slightly touchier as expected, power gains are subtle but noticeable. The sound is the real kicker. Above 4500 rpm the car really growls in a good way. Its quiet at cruising RPMs so the sound isnt obtrusive and only wails in the higher rev range. A great purchase" —Neil P from Bayonne, NJ bought an Injen SP Series Cold Air Intake for a 2009 Acura TSX.

K&N Cold Air Intake Replacement Filters

Regular Maintenance

original filter had been in place for 4 yrs with nearly 50,000 miles on it. i noticed a decline in performance & fuel economy. ordered a replacement filter, easy install and back to good running health in no time. K&N is GOOD for your engines. I would recommend it to anyone. View more reviews...

Injen Replacement Air Intake Filters

Just what you need!

I bought this air filter and when I say it came in perfect condition, I mean it. It came spotless, with a nice stainless steel adjustable tie, and it fits very snug on the intake. It sounds so nice at wide open throttle as well, anyone looming to buy an air filter should consider buying it from INJEN View more reviews...
