No intake has yet to produce proven gains on a chipped a4 2.0t. While the carbonio may increase airflow especially at higher revs, it also raises air intake temp. and does not increase power. Same with the evoms intake, it just raises the intak temp.

Yes, the K&N and Carbonio are mutualy exclusive, it makes no sense to do both.

When using the K&N, to avoid oil build up on the MAF sensor simply clean the excess oil off the filter before installing it. It also can't hurt to clean the filter periodically.
