Comments: Almost sick of K&N. I have had on allot of cars. Seems as the years go by, they rely more on there name. Instead of producing a good product. I also have a 2006 Dodge Ram 1500 Big Horn Edition. I installed a ProCharger unit. Purchased the recommended K&N filter. About a month later was in the shop due to catastrophic failure!!! The K&N came a part internally and half was sucked into the motor.
I have been running AEM now for about 20k miles NO problems.
BOYCOTT K&N!!!!!!!!!!!!!!!!!!!
