What if we told you that there was an air filter out there that, even when dirty, outperformed generic paper filters? You'd get one for your car, truck, van, or SUV today, right? Well, here you go: The Kool Blue air filter from the folks at Accel actually incorporates the dirt it traps into the filter media, using it to trap even more dirt. The end result is that the Kool Blue air filter is so efficient, it flows more air when it's filthy than a brand new paper filter does out of the box. If that's not enough reason to buy a Kool Blue air filter, there's more. Kool Blue air filters utilize an oiled cotton fabric for the filter media, instead of paper. That means a Kool Blue air filter is sort of a cross between your lawnmower's air filter, with its oil-bath technology, and a regular cotton high-flow filter. But since the Kool Blue air filter combines the best of both worlds, you get the great airflow of a cotton filter and the superior dirt-stopping ability of an oil bath cleaner. And since Kool Blue air filters are washable and reusable, the Kool Blue air filter may be the last air filter you buy for your vehicle. We stock Kool Blue air filters for a ton of different applications, all ready for immediate shipment. And with our everyday discount prices on Kool Blue air filters, it has never been easier to give your car the Kool Blue air filter performance edge!
