Oh SNAP!! Everyone stop! Don't buy the WizAired!! He has a poll!!!!!
Even by the end of that thread, the main antagonists against the WizAir shutup when they realize the HP gain with the K&N is all guesstimate and never actually dyno'd, while the WizAir is a proven custom design for the W-body which is dyno'd. I fail to see what you hope to prove.
Overall, that thread shows more people have the knowledge to step up and back their vote for the Wizair than just voting for the K&N and giving no supporting evidence.
