Air filter recharge kits are the perfect accessory for your aftermarket air filter. Many performance filters need to be cleaned after a certain number of miles, and to ensure peak performance, you need a recharge kit. They consist of one product to clean the dirt and grime off of your aftermarket filter, then a separate spray or squeeze bottle that replenishes the oil that keeps your filter working efficiently. Recharge kits are necessary to service your reusable air filter and help keep them lasting a lifetime. Still have questions?
