Looking for new panel filters, deciding between these two which is best?
Or any others?

 

R2C filters are some of the best you can buy. I'd go for those. Kyle @ ImportPartsPro is an excellent vendor. I believe he stocks the R2C filters.

 

I don't know what you mean by "best"... best value, best filtering, best flow, best fit...

For me, I like the K&N filters and have used them on my cars for over 30 years.
Last month I dynoed my car with the factory air filters and the K&N panel. The K&N made good gains from 3600 RPM to redline.

 

R2C is a dry filters, vs K&N being an oiled filter. I'd stick with R2C, no need for oiling them. One less thing to worry about.

 

I run Afe dry filters

 

Afe ftw!
