K&N E-4640 Air Filter Product Reviews

Thursday, November 2, 2017 - Part E-4640
The filter was a replacement for an after market air cleaner. It fits perfect. Great people to deal with.

I used the on-line chat feature to figure out which filter element I needed, which worked really well. And what can I say about K&N filters, I have them in all of my vehicles and have for years.
