K&N 33-2442 Air Filter Product Reviews

Monday, October 24, 2016 - Part 33-2442
I received the filter when promised and had it installed in about 15 minutes. The cost of regular air filters is about 50% of what the K&N filter cost so it will pay for itself within a year. I can also tell the engine is getting more air since the engine used to run a little rough at idle...runs smoothly now.

Awesome product. It frees up horsepower, better acceleration and mileage really goes up if there's cold weather. I highly recommended to anyone that wants to save money.

I had my dealership install the K&N air filter at my last service. My 2010 Buick LaCrosse still has relatively low mileage (28,400mi) and the performance is excellent. I would like to keep it that way. That's why I wanted to start using your air filter.

I have not installed the filter, at this time, so cannot really rate it. I have previously used an air filter, from K&N, and was satisfied with it. The savings, of this filter versus dealer pricing is huge.

This product, like all K&N products, is outstanding. I have K&N in five of my six vehicles but don't have one in my 2015 Chev. express with a 6.0 engine. Hope you can help with that soon. Thank-you
