K&N Air Filters Reviews

Not too big not too small

Reviewed By Paul B (Port Saint Lucie, FL) Reviewed for a 2008 BMW Z4 —2/23/2018 4:50 AM

K&N filters air to the proper degree. Paper filters restrict air flow by filtering particles too small to make any real difference. My mechanic says after cleaning don't bother to re-oil because it's almost impossible to replace the very light mist of oil of the original correctly. The multiple layers of cotton gauze are sufficient to protect your engine.

aFe Pro-Dry S Air Filters Reviews

Definitely a good-bye (good buy, too)

Reviewed By Norman C (GOLDSBORO, NC) Reviewed for a 2011 BMW Z4 —11/29/2012 2:45 PM

Good-bye to a good deal of throttle hesitation on my Z4. Running some other stuff through my recently-purchased used car's fuel system (to get it back in shape, too); but the added air flow vs. the brand new OEM filter is performance-obvious (a good buy). I really like the fact I do not have to re-oil the high-end aFe Pro-Dry air filter, which itself isn't difficult ... just one less thing I have to do.

Exact match and plenty of life outta these filters

Reviewed By Paul P (Collingswood, NJ) Reviewed for a 2007 BMW 3-Series —2/18/2018 7:40 PM

I received my replacement filters. They were already oiled and ready to install. Very happy with the ease of install and quality.
