Track results K&N, GREENS, STOCK FILTERS! Pics up!!
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

Your results confirmed my G-tech results which showed K/N's had a .19 average second drop in my 0-60 times over the stockers
THANKS FOR THE GREAT WORK
See yeah

It really don't matter the time difference between the aftermarket filters in my opinion cause the driver could of had a better reaction time and less spin so its all whatever one likes as long as they are not stock filters
if anyone cares to borrow me a set of other filters to test(I will pay for return shipping)It looks like there will be another track day in mid-November.

Good results. Multiple runs would help, but this evidence is pretty strong. Turns out, the 944 I bought has a K&N filter, and it was cheaper to buy the "filtercharger" cleaning kit than buy a Porsche OEM filter, so I guess I'll start drinkin' the Kool Aid too.

They are the best run from multiple runs with engine cooling inbetween and the same driver. I had the K&N already in car just bought Green filters not knowing and wanted to provide the differences for others to compare that's all. Just wanted to prove OEM filters are a restriction.

Don't forget, a LITTLE oil goes a LONG way. I have about four cans of left over oil, but yet they NEVER give you enough cleaner

The stressful part is that you really don't know whether you've used too little oil. The red coloration method starts to lose effectiveness as the filter gets older and blacker, so you're left guessing. And it's not like you're going to notice any real degradation or performance problem for using too little oil -- at least not until you've done some damage. All in all, I'd rather have an OEM filter so I know I'm actually filtering; but since it came w/ K&N, that's what I'll use.

So were filters the only thing that you changed between the runs? If you can get a near half second gain on your 1/4 mile with just filters, I might have to give this a shot as a first mod.

You know what you need to try now? is NO Filter at all on (1) run I've read a lot of drag racers do this (it wont hurt your car) it would be interesting to see what your time difference is compared to all the filters you've tried, there's also some really good Foam filters which are supposed to give even better perf than K&N or Green.

also found out on the track that the previous owner must have installed a LSD so I have both wheels pushing evenly. Its probably why she felt so easy to drive in the snow last winter

It was mentioned while we were there will try it on our next track day.....as I mentioned before if anyone wants to send me other filters to test I will put them to the test also. As for foam filters I never heard of them so if you could post a weblink about it I will appreciate it.

I don't know if it helps but I have magnecor 8mm wires, Denso Iridium plugs, SL55 splitter and SprintBooster also found out on the track that the previous owner must have installed a LSD so I have both wheels pushing evenly. Its probably why she felt so easy to drive in the snow last winter
