best thread I have read in along time... from MBworld

Ok Guys

Here are the results on the track that tells differences if any with the more popular choices compared to stock air filters. Basically I see no major difference with the aftermarket filters but definitely see a difference with the stock filters. All runs were by the same guys with time inbetween for cooling while replacing filters. Conditions were near perfect for the SC cars. Its all preference guys between the two aftermarket filters. My preference is the Greens but the K&N seem better built. By the way if you haven't read my thread on this the K&N cleaner does a better job at cleaning the Green filters.

The 1st pic shows the best run with the K&N filters, (13.4360 @ 104.58)
The 2nd pic shows best time with Green filters, (13.4602 @ 103.93)
The 3rd shows best with stock filters. (13.9038 @ 101.60)

The 4th run well its my car besting a stock E55 who's non-owner driver made a huge burnout but almost caught me but I will take the momentary win.
