If you have a high performance reusable filter, than you need to be sure to keep it flowing as freely and as easily as the day you installed it. The AEM air filter recharge kit is designed to clear out all of that dirt and grime from your reusable filter, opening up the pores of the filter, ensuring the best possible airflow. While reusable filters are touted as filters that last a million miles, they require maintenance just as often as a paper cartridge filter. That maintenance is not a replacement, though, just a cleaning and re-oiling. The AEM air filter recharge kit provides you with everything you need to remove the old oil that catches the dirt particles and to reapply the new oil. Old oil gets thick and clogged, and over time, it will clog the pores of your air filter. That means that, without the maintenance that the AEM air filter recharge kit lets you perform, your expensive performance filter will actually reduce your horsepower. So keep your engine breathing well with the AEM air filter recharge kit. Not only will you have more horsepower, but you will have better fuel mileage, as well. Auto enthusiasts certainly deserve superlative support while shopping for reliable parts for their car or truck. Accordingly, we maintain a twenty-four hour a day technical assistance desk to answer your calls. Nobody likes to pay for shipping, so there is free shipping for every order $50 and up. If you spot a lower price elsewhere, give us a call - we will beat any price advertised elsewhere.
