K&N air filters...

I've been considering putting one on my '84 300SD. The dealer wants $50 for a conventional filter and a K&N is $77. Has anyone used one on a diesel/turbodiesel?

Thanks,

Tim

I got it in my car for 30,000 miles so far... I know my engine is a bit more responsive... fuel mileage went up a little bit... maybe 1 or 2 MPG.

It beats those brittle paper filter... although the paper filter traps more gunks. I really don't think it is that much of a difference in those particles that got through... they get burned and then out the exhaust.

Diesel engine probably benefits more from K&N filter... also those weaker engines...

Only thing you have to remember is to clean that air filter with K&N detergent and then oil it with K&N filter oil for best protection.

Letting the engine inhale particles is exactly what you don't want - unless you want a good reason to rebuild your engine? They don't all get burnt, think about driving through a cloud of sand or similar grit... it would make short work of anything inside your engine.

K&N filters flow more air whist 'aparently' doing as good a job of filtering the air from particles as the paper style.

If you flow more air, you need more fuel to mix with it, this doesn't necessarily mean less M per G overall, as you may be producing more power lower down in the rev range, but you'll often find it does.

You should experiance more power as a result though, especially if your engine is all EFI and can correct the air/fuel mixture properly.

I've only had a K&N in one car, and it made a decent enough difference :)
