K&N Air Filter for AAN?

[geneandbolly]

does anyone know if the s2 and urS6 air filters are the same size? i enquired about this one on ebay and he needs to know the size of mine (fnarr fnarr).

do these things really make any obvious difference to performance?

Stick with the Audi part on this id say. You might get a bit more of a wooosshh noise out the k&n but that's about it.

I have a K&N on mine, slightly more wooshy coming off boost, but not to any great degree.

Much of a muchness.

They make more noise not more go and can coat the mad in oil leading to running issues. Renew the own paper one often and it will be better

I think the answer should be obvious after you have finished reading.

Anyone want to buy a second hand K&N?

New paper element is your best / safer bet.

Not everything aftermarket is better than oem.

K&N what £45.00? That you need to maintain. Na,the paper Audi one all year long matey for clean air to keep you onwards and upwards of that horrible misfire you used to have Not any more!

I've Used the k&n filter and it's never bothered me. Car ran the same. I run paper Mann filter now though. Gonna run my cone filter soon and my intake mod. Woosh woosh

thanks for all that info, chaps. i don't want any whooosh noises and love the standard "double glazed" silence of the tub. a service is due at mot time at the end of the month so i'll keep everything standard as mother audi intended . .

Forget about the K&N.
I did a test (on road power/torque/acceleration) last year of a new K&N panel filter vs. my regular OE (MANN or Knecht) paper filter with approx 20.000km on it.
This on a RS2 that pushes 500+hp and 700+nm.
No difference at all, so the K&N went back on the shelf, as I don't wanna oil my MAF.
Here is the thread with graphs and acceleration figures:
