Installed within the last 9 months on my 2015 Jeep WK2 with K&N cold air intake

I noticed a slight increase in throttle response. increased miles per gallon! Smooth idle! My favorite part about this spacer is that it makes a slight whistling noise at about 1/4 throttle while cruising, while my average per gallon before the intake and spacer combined with a cold air intake was 16-17, now I'm cruising at 20 through the City. 22. great product Be sure to disconnect the battery before installation, a very important part of the ECU to relearn how the engine responds with the throttle position sensor!
