Perfect product, just didn't fit my shaker set up. Car issue, not a product issue.

I have to modify my air cleaner a little more but it fits and looks good, no pics at this time. I love and have all K&N's in my Dodge. Air filter, fuel filter, breather and oil filter. Now I have an air filter in my Jeep.
