You're call on the K & N but it's pretty well documented and dyno'd that those after-market filters add nothing to the power and a MAF is an expensive thing to replace.

Just looking a tthat intake... the OE draws air from outside the vehicle (cooler) while that K & N is drawing hot air from the engine compartment. Cooler air is more dense, has more O2 and burns better.

You may or may not get more air through your current system but it's hot air.

I'm not a pessimist. At some point the world sh!ts on everybody. Pretending it ain't sh!t makes you an idiot, not an optimist.
