Review on 🏎️ High Performance K&N Cold Air Intake Kit: Guaranteed Horsepower Boost for 2004-2007 JEEP Liberty (77-1540KP) by Duane Ramos

Revainrating 5 out of 5

Worth buying: Replacement parts

Easy to install and good looking. No noticeable increase in engine noise on my Liberty, but you can hear air being sucked in. It smoothed out the idle, lowered the idle by 200 rpm (yes, I preinstalled a stock clean filter), and made a noticeable difference in acceleration. . The purchase is worthwhile.

Pros
  • WORLD CLASS PROTECTION: Push the limits of engine protection by protecting your engine from harmful contaminants
Cons
  • Hard to tell
