does anyone use these and have you found them restrictive at higher RPM's?
Where can you find out the CFM air flow for them?
Would take a look at K&N, last time i look at this they had the information.
Give RamAir a call 01793 296344.
I found them helpful when I was changing air filters on the s/c hairdressers.
HTH.
