K&N is a very decent filter, but the price in them is mainly for the name K&N, Enrique pointed that out very well. They are only nice and useable in the fact that you can clean them, performance wise-not a whole lot to gain there. They show how their filters "straighten" air flow through the grids built in the screen, but that is not effective, whatsoever, after making a 90 degree turn to hit the throttle body (which is very turbulent for airflow), it hits another 90 degree turn to actually make it to a intake valve. That is why Swirl polished valves are worth their weight in gold, that is where the swirling effect takes place. Tornado's=Uselessness for the same reasons, if you were maybe to make tornado's for each runner in your plenum, then they "might" be of value, but after all of the twist and turns our intakes endure, there really is no safe bet other than ported/polished heads and swirl polished SS valves (even sodium filled valves to shake off the heat would be nice!).really? wow good to know Z. thanks man. in LA we do alot of freeway driving almost everywhere. wonder if thats country-information?
what breather element do you prefer then? whats the thickest and best. price being no object. who was the OE mfr?
