I have installed K&N cold air intakes on all three of my vehicles. As usual the install on my 2000 Ford F-350 was straight forward with zero issues. And as usual ditching the restrictive factory intake and filter allows the engine to breath so much easier. I have no problem recommending K&N products to my friends and family.
Impressed with the build and fit and finish. Instructions were vague however AEM has a very good youtube install vid and with the paper instructions all bases covered. Performance on the car is very good. I feel like the car ECU is still learning the improved airflow seemed to drive better 3-4 days after driving it. The CARB certification makes this now a no brainer as far as intake. The strut arm is coming next, shame Auto Anything doesnt stock them anymore [why?]
