Review on 🔧 Improved Performance: K&N Cold Air Intake Kit for 2007-2009 FORD Mustang GT (63-2565) by James Edwards

As mentioned, the instructions leave a lot to be desired. You'll receive minimal hardware instructions, so look at the assembly diagram (with a magnifying glass) to see which specific bolt and nut goes where. I started installing at 10:30 am and at 12:20 pm I was already testing. Including a short lunch break. It seems that the engine is easier to breathe and picks up speed faster. Tight pants. I am very satisfied and absolutely satisfied. Sounds great with my GT500KR exhaust!
