Skeptic. Until I see a YT video of a 3rd party testing this on the same dyno under same conditions, I don’t see how K&N or anyone improve the factory intake.

Agree completely. I would never purchase something solely based on the manufacturers literature.

The 427 peak WHP on their graph seems low. Not saying they are scamming, but 30 WHP and 30 Ft. lbs. tq would be really good gains.

If a 3rd party independent source dynos shows similar gains, I would be a buyer.
