Thanks for all the input folks! So if I understand correctly, it really hardly matters at all what air filter I have on my engine so long as it clears my throttle linkage and my hood?
I wonder why there are calculators for required air cleaner area, and many different filter sizes all for a 5 1/8" carb opening?
You know, I forgot that the cleaner surface is pleated, which should increase the surface area greatly! I thought that was to give more surface area for particulate accumulation. I'm not sure folding a piece of paper into an accordion shape will let more air through it than leaving it flat.
Well I must say I agree the sidepipes will make the most difference. I guess I'm still in a bit of confusion over the air filter but then what's OCD for anyhow?
Regards,
Dirk
