Bartolone Racing V2 Performance Air Filter for Losi 5ive (3pc) (SM308)

Bartolone Racing Performance Air Filter performs best in the worst of conditions. That’s why our Performance Air Filter has been the chosen air filter of all serious RC Racers. In this dirty, dusty environment, air filtration is extremely critical to the performance and protection of the engine. Our filter is designed to be used with velocity stacks. Our new and improved V2 air filter has three stages of foam filtration, and if ran with the included outerwear pre-filter it makes it a total of 4 stages of filtration. The included outerwear pre-filter also helps block water, dirt, sand, road and other dirt debris. NOTE: Filter Needs to be oiled before use. Filter is designed to be used with velocity stacks. Filter and pre-filter is washable and reusable. WHY FOAM IS A BETTER AIR FILTRATION MEDIUM THAN PAPER OR GAUZE. The principle of how foam air filters work is simple: “Open Cell” Polyurethane Foam is wetted with specially developed filter oil. The “sticky” filter oil is suspended in the path of the dirty air on the strands of the web-like cell structure of the foam. This makes it impossible for dirt to pass through the depth of the filter without sticking to the strands. As the outer strands become loaded with dirt particles, the wetted strands down stream start trapping dirt, allowing the entire thickness to be utilized. This prevents surface loading or air restriction for 80% of the service life of the air filter element. When the filter is sufficiently dirty, it can be easily washed, re-oiled, and re-used.
