Works Very Well

This has to be one of the easiest things to add to your jeep to help increase performance. It works very well with my K&N Cold Air Intake. I was very impressed.

Great product, does what they say it does, better performance and the gas milage is about 2 miles to the gallon better. Also works great with my K&N cold air system.
