K&N air Filters
I race autocross in St Louis. It’s great fun and I’ve really learned how to push my automobile to it’s limits. One thing( among many) it’s lacking, is power…
So when I started racing last year, I wanted an easy modification for under $100 to give me a little umph. I bought some cheap aftermarket ram air intake. Basically, That just made it sound cool. that’s about it.
Last weekend I put a K&N filter in place of the old filter…. Wow. The car runs better, Zero Hesitation, I can’t wait for the first race this year… See if I can actually beat someone this year
