Attention: TDR Forum Junkies Sunday night I removed my K&N drop-in filter for cleaning. I put in my used standby Wix filter until the K&N dries and is reoiled.
Driving home from work, I learned something about air flow. Talk about smoke. I got on it at a light so I could change lanes. In my rear view mirror all I could see was a black cloud across three lanes of traffic. Some cars were actually swerving around it. Now the Wix air filter wasn't new, but it was still serviceable. The last time I used this filter, I had my stock injectors and dv's in. I did not get this kind of smoke with them.
With the dirty K&N filter I get some smoke off a quick launch, but nothing compared to above. Maybe half of the smoke.
I did not detect a huge difference in performance around town, but the amount of smoke gave me a indication of the amount of air flow difference between the two filters. Obviously the K&N flows more air which in turn the engine puts out less smoke. The turbo was quieter and you could hardly hear it sing with the Wix filter. :{
I have read several threads about a K&N letting in dirt and dripping oil. So I also removed the intake tube and inspected the turbo fins. Everything was clean and oil free. This is with 15k miles on the filter.
