Not disputing that it doesn’t work, but Outlaw Engineering’s R&D seems limited to me. The extent of their reported testing was limited to inlet manifold temps & for short burst of power from the engine (ie. dyno runs & 1/4 drag). There's no mention regarding engine temps or manifold temps after a track session or daily city driving.
My initial & main concern would be where does that excess heat go??. Their response in the FAQ, implies the trade off is an increase in water temps.
Personally if your after a cooler air intake mod which, primarily what this gasket is, a well thought out CAI &/or intercooler water spray kit would be a better bang-for-ya-buck for performance gains....just my 2c.
