Want a little more pep from your engine without a complicated install? Swap out your stock paper air filter for this aFe Power performance filter. It's a direct 'drop-in' replacement, so it fits right in your factory airbox – no modifications needed. The magic is in the 'Pro DRY S' synthetic media. It's a three-layer, progressively finer mesh that flows more air than a paper filter (which can mean a bit better throttle response and horsepower), but still traps dirt incredibly well. Best part? It's completely washable and reusable. When it gets dirty, you just clean it with their special kit (sold separately), let it dry, and pop it back in. No need to buy a new filter every year. It's also OIL-FREE, so there's no messy oil to deal with or risk of contaminating your MAF sensor. Made in the USA with a lifetime warranty. A smart, eco-friendly upgrade for your car, truck, or SUV.
