Hey bro's, read this response on youtube and wanted to share with all of yous.

"tsk tsk.. you noobs who know nothing about the new HR motors.. AEM, Injen, Stillen, Fujita... all those intakes do nothing and some even make your engine LOSE power.. the new HR motor's intake system is already optimized.. it's "restrictive" air box is actually stacked and engineered to use the air pressure inside the engine bay to force in the maximum amount of air into the engine. Removing that air box just undoes what Nissan engineers designed for the HR. Use that money for an exhaust."
