K&N 33-5039 Air Filter Product Reviews

Monday, June 27, 2016 - Part 33-5039
I installed the K&N airfilters in my Amg GTS. Throttle response has improved and I can hear the turbos spool up. It adds more sound to an already magnificent sound track. I paid 128 canadian for 2 filters and definitely great quality. I have used K&N in all my previous and current performance vehicles (srt8 viper, r35 gtr, audi r8 v10, porsche pan turbo, bmw 650,e63 s-amg and previous ford trucks). Never had 1 problem with them and there was a definite improvement in power and fuel mileage.
