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.

I'm impressed with the results of his "test". It is hard to believe he shaved off 0.6 seconds just from filters alone. But it begs the question how well can the K&N or Greene filters filter if they let that much air in. I have had K&N filter on many of my vehicles. The throttle response was always considerable. Although I had never dyno'd before and after a filter change alone I suspected there was some gain I did see from the filters. Usually though the exhaust and intakes were modded simultaneously and dyno'd after both.

I may need to stop buy the store on the way home to get a pair. As posted earlier in a separate thread I am in the mid to high 12 seconds already and the car is completely stock. K&N could be a big difference.

I will be on the dyno Saturday morning assuming all goes well. I'll post the results. I am getting stock hp numbers for my car. I'll swap out the filters after the first 3 runs(always with proper cooling time for accuracy) and see what happens.

I have a sense that proportionally bigger increases would be seen on the track due to the ram affect our intakes have versus a dyno in a static position.
