Cold Air Intake vs. Topless K&N
 

I just bough a 200 a6 2.7t quattro and i cannot find a stock replacement K&N OR and Cold air intake system for the car. I used to have an A4 3.0 quartto...so the A6 is a new beast for me.

Does anyone have any suggestions, recommendations, etc.....

you can always get a K&N Cone filter and just stick it on the other side of the maf. pretty much how most intakes are

your stock unit is more effecent. think cold air where does it come from? if you take all the routeing out and put in a ait filter in the engine compartment. it becomes a hot air intake. cold air denser more oxygen. more combution effecency. leave it stock unless you just wanna kill horse power for sound
