K&N Air Filters Reviews


I am a believer!

Reviewed By Steve B (Buffalo Grove, IL) Reviewed for a 1997 BMW 7-Series —10/31/2010 7:03 AM

After installing the K&NB in my old 97' BMW 740I I am a believer! Gained 3MPG in the city and 5MPG in Highway! Installed one on the wife's 03' Explorer and will see how that works out but I am sold.

K&N Cold Air Intake Replacement Filters Reviews


K&N air filters are great.

Reviewed By Matthew D (METAIRIE, LA) —11/15/2017 4:32 AM

Replaced a cold air intake air filter with a k&n filter and made a noticeable difference. Easy to install, looks and sounds great, and doesn't cost too much. Would buy again.

Interesting Product, Couldnt Hurt

Reviewed By Paul B (Converse, TX) Reviewed for a 2014 Dodge Challenger —11/9/2017 3:53 AM

Purchased this because I use a CAI that draws air from the fenderwell and is directly exposed to road debris and possibly water. Was a little of a pain to install but only because of my set up. Does not seem to be any from of restriction and I can see where it will help keep the filter clean. It also may repel some water and road spray.
