This is a Motor Saver Three Stage Off-Road Air Filter for the HPI Savage X, XL, 21, 25, and Savage SS trucks. These air filters work GREAT. If you want your engine to last longer, you need this filter. The three stage filtration helps stop the sand and fine dust that destroys these small engines. This high volume air filter also features an easy to check inner filter, so you know when it should be cleaned. These are much easier to check, clean, and maintain than the stock filter system, and they work better too!
