Apparently the 3a racing filter was deemed the best by a fair margin for air flow/filtration, however RPW and a few other forums claim that the FTO/mitsubishi specific K&N filter is guaranteed to be 'better' but doesnt give any figures or justification other than that its a specific filter.
My simple question is has anyone here tried both/1 or has done some more indepth research and found out which one or is it a clear cut case as i know jack all about brands and specific filters etc.
Moderators, if this is in the wrong section please move it, i just dont want to be hunting down a long forgotten thread to post a simple question
