K&N 33-2411 Air Filter Product Reviews

The CTS appears to breath better with what feels like more acceleration in the 5k-6k range.

I already notice the increase in acceleration. I love the deep throaty sound when I punch it. Waiting to see my gas mileage increase, to soon to be calculated.

Very satisfied with my filter. Quick delivery, and once installed I noticed a 2 mpg increase in my overall mileage. Can't wait to put it to the test on the long haul.

The filter is good, fits and works. ....just like the others I have used in my other vehicles. Shipping time and cost kinda spoils it. The ever questionable price of the on-line shopping convenience....

This is the third Cadillac I have used K & N air filters on. I love them I will continue to use these filters.
