Stock intake fascia is open inside the passenger side, some say its for "engine cooling" I say it's stupid.
Also the R is air straight to filter and back through inlet piping. Stock forces air along a slimmer fascia, down a tiny duct that goes back up behind the intake box, back down an even smaller hole emptying into the bottom of the stock filter box, air then has to travel up through the dumbass plastic bottom "filter holder", through the stock filter element and then force it's way 90 degree back through another little angled hole directed towards the stock inlet pipe. Hence why it has such a muffling effect.
No thanks
Sure there's cheaper intakes that are literally just for sound, I choose the one that's made for this car with quality
