Nice test. Too bad it tests nothing other than recirculating dust will eventually all get picked up by the air filter as the holes get plugged.

And hook up a gage to your aircleaner when you get a chance. Tell me what it reads at idle, 2000 rpm, 3000 rpm, 4000 rpm, etc. Tell me if you get 26 inchs of water column. Or 31". Or maybe none, hopefully.

And 100,000 miles on track and off? On the same engine? What kind of race track is this and who built your engine?

I may as well bite. I build my own engines. No, I've never run an old Mercedes diesel on the track

I don't have any first hand experience of what a tiny bit of dust will do to this engine but quite frankly I don't really care. If it somehow magically blows it up then I'll buy you a beer and tell you you were right.

I have a Toyota Supra twin-turbo, a Formula Mazda, and my Lotus running on K&N style filters. The engine in any of those cars is worth way more then the entire Mercedes.

I'm an active SCCA member and do road courses (Phoenix International Raceway, Firebird International, Arroyo Seco) and Solo II autocross.

Should I take the Mercedes out there next time?

No point in taking the old clunker out there.

My point is that the test desribed above is bogus.

And the comment of 100,000 miles on and off the track, implying on the same engine and still running strong, well, you know that's bogus too.

If you want to run K&N, go for it. If you take your engines apart often, why even run an air filter? It may be better to remove it entirely and do some work with air flow improvement into whatever induction system you use.

But for longevity of an engine, K&N does not cut it. That's my story and I'm sticking to it.

Good luck with the clunker and in your racing endeavors.
