Thanks for details information,very helpful.
The K&N57is are losing low end torque and rarely show anyimprovement against stock.
The K&N Apollos lose power against stock. Not a single test has shown an improvement as yet wherever made in the world.
The typhoons are not bad, However, only one of them comes close to the AIRs I have designed.
