FS: (2) K&N Air Filters for 43 and 55 (n/a)

Selling a pair of drop in K&N air filters for N/A m113 AMG engines. These were used in my c43 for approximately 20,000 miles, with no issues noted.

Product number 33-2183.

These K&N filters MSRP at knfilters.com for $113.98 for both, before tax. I am asking $65 shipped, CONUS, firm. Thanks.

I'd be careful with any oiled filter. the oil will end up on your mass air sensor wire and cause issues.

Honestly, I could not tell if there was any difference in sound. My exhaust was straightpiped after the secondary cats, so it was relatively loud to begin with.

A general rule of thumb that works for me is to remove the filter from its package (when brand new) and let it air out for a day or so before installation. As a result, in the 20,000 miles that I have driven with the K&N air filters (the time most prone to have problems show up), I have not had any CEL or MAF-related issues. These are broken in and good to go for another 30,000 miles before requiring any re-oiling.

However, this is just my experience; I am not in a position to debate a Mercedes mechanic. YMMV~
