K&N 66-3120 X-Stream Top Assembly Product Reviews

Tuesday, December 20, 2016 - Part 66-3120
I was pleased at how quickly my air filter and cleaning kit came...I've got a 72 Nova w/a 2 cowl hood that I'm installing the filter in and am busy enough w/other items that I haven't even opened the box yet. It may be a few weeks or some months, I can comment further at that point.
