K&N filter for OLD Audi?

Hi, is it worth it to get the K&N filter for my '86 5K TQ? Will it make much difference? The car is in peak mechanical condition now
(unless I'm missing something)

Thank,
cp

Yeah, it lets more crap through, and makes your charge air dirtier.

Use a stock filter - they work great.

E.P.

Waste of time and money.
It may make more noise, allow more rubbish through to wear the engine and
has the potential to contaminate the MAF.

Something I know.

Wow. K&N presents positive data! Shocker!

Now, how about *independent testing*? That's usually not anywhere NEAR
as positive.

Actually, new, freshly-oiled K&Ns do not filter as well. And the
differences between a K&N and stock filter in engine power are
negligible.

Placebo effect.

:roll eyes:

Independent testing results disagree with your, uh, "assessment."

And *especially* in a turbo application, I wouldn't screw around with
dirty charge air.

But hey, if you like dirty intake air for no appreciable gain - have at
it!

I've been warned off them and removed one from my '96 S6.

Something I've done on my S6 is to replace the stock air intake hose, which
snaked around the engine compartment before getting to the air box, with a
4" hose connected to the oil cooler intake snorkel. Have seen increased
accelaration performance.

The AAN engine can suck harder than the stock air intake can supply air to.
May be this is something you could investigate for your car. The mods I did
cost $20.

No. Not for an old, and not for a new.

Cheers,

hmmmmmm I think I'll do an experiment, before and after, and post the results. maaaaaan it's amazing how fast a 20 year old 2.2
liter engine will go :-))))))))))

Remember to try a new, stock filter as a control. Otherwise your
experiment doesn't mean much.

Yes, I put one in a month ago. Going off on a long trip, will see if the K&N makes any difference.

ooooh S6, I'd love to have that if I was living in Europe

Yeah, it sucks to be in the U.S. with this car - I always want to punch
it up to 100.

But it's still a nice car, and gets decent fuel mileage when I don't
overuse the boost.

E.P.

P.S. I think you're making a potentially expensive mistake. You're
not going to notice any change in power.
