K&N on IS350
Put the typhoon on this morning, sounds great and gives a small but noticeable performance difference. The car is a bit snappier in the lower and mid rpm ranges. A lot of folks on here claim that CAI's dont do much, I dont think most people know how to interpret the data on a Dyno sheet. K&N did their base line runs and modded runs under nearly identical atmospheric conditions which is as it should be. I waited for a day like the one they used to do the mod and go out and road test the car. The claim of 12 rwhp and 10 ft lbs is correct given the conditions of the tests, on different days it wont be so. My opnion is that for $292 ( including tax and shipping) and about an hour of my Sunday morning the CAI was worth ever penny.
