the direct replacement drop in filter will not decrease power. the loss of power from warm air is if you replace it with a cone style filter that has no aid from a heat shield. you will gaine horsepower from the inbox filter, if you want to feel the diference between the two, go grab a piece of paper in put it up to your lips and try to suck air through it, now get a cotton t-shirt and try to suck air through that, much easier. the piece of paper represents a stock air filter or paper filter, the shirt represents a k&n, thats what ur car has to do. also if u have a cat-back exhuast you should really be able to tell a difference between a k&n and stock. it should also help out on gas mileage, and will NOT cause any harm to your engine even tho some people think it will

it will make ur car run leaner, its pointless to re-tune ur car just for that. if u had an exhuast put on it would make it run richer which will even it out so.......

also that engine bay is hella clean

Intake will make it run richer? I thought you said it will help out on gas mileage a small bit?

I'm confused :(

if u disconnect the battery while doing an intake and plug it back in the ecu and 02 sensor can adjust to it so i hear

Nice 535...
Just remember if you use a K&N, don't spray too much oil on the filter.
You'll ruin the MAF.
