The filter, as with all the other K&N filters I have purchased over the years, appears to be working as expected. I'll continue to purchase your products whenever the occasion/requirement arises. Thanks, Ken Upland, CA

I installed this air filter in about ten minutes after disconnecting air and oil breather line from the air box cap and removing factory filter the K&N filter fit the profile area exactly. The only issue I found was the lip height was a bit taller so when reinstalling the cap/lid I found this to be some what troubling. The height of the K&N seal surfaces were taller causing more effort to push the lid back into the tabs profiles on the air box then holding/pressing down the lid to lock the snap tabs in place. This however prompted me to double check fitment before deciding it was good seal with no obvious gaps around the filter box. Hope this helps looking forward to replacing the one on my 08 CVO Harley this spring.

The truck seems to run better with the factory filter. The gas mileage dropped by 3 mpgs with the k&n drop in filter, as if that isn't bad enoungh considering its a hemi engine. These filters are more suited for heavily modded engines, but the delivery of the filter was on time as estimated.
