anybody sucking dirt with r2c air filters

[stock car driver]

Air filters are kind of like set-ups. You change one thing and you compromise something else. So as the filtration efficiency goes up, so does the restriction. As a racer we must
find the right balance between how well a filter traps dust and how well it flows air. There is no such thing as a filter that stops all the dirt and also has zero restriction nor will it ever
be achievable. Its been proven many times that less restriction(lower efficiency) makes more power on the dyno so do your own research and pick what's right for you.

I'd bet that if you put an engine on the dyno and made pulls with an R2C and some pulls with a K&N that you will make bigger numbers with the K&N.
What are your thoughts on that Mr. Ed? I've done my own dyno tests with a K&N vs. a Wix Gold Paper filter but haven't had one of your filters on there yet. If you'd like to send me
a free one I'll gladly try it out and post the results right here!

They have no need to give you one for free to test...... Though he said if you buy one and dont like it youll get your money back from him.

Ive already done the back to back testing at least 4 years ago and I have a NEW r2c in a bag here that I have also tested my USED and filthy one against on the chassis dyno and my USED and cleaned one against on the chassis dyno...


Kn was down 15rwhp .... Thats a test I did over 5 years ago when I threw all my kn away.



Thanks Ed for coming on here again. I didnt even think to email you about this thread, but apparently someone else did.

Jeff Joldersma Racing runs r2c exclusively since 2009.

I bought an R2C filter last year and as long as they make them I will never by another brand of air filter. It has kept my engine clean and it's easy to clean and reuse.

I had run Wix paper filters before and replaced them every 5 races, never ran K&N mainly because it doesn't make sense to me to have to put oil on a air filter.
