Sprint Filter free-flow air filters are made from polyester. This unique material delivers exceptional filtration performance. Thanks to its uniform weave, the filter barely restricts airflow at all.

The P037 filter offers slightly better filtration efficiency than the P08 filter, and on top of that, it’s completely waterproof. That makes it an excellent choice for extremely dirty and dusty conditions.

Cleaning your Sprint Filter is easy with compressed air. If it’s really filthy, you can also wash it with water and a mild detergent, then dry it off with compressed air. There’s no need to oil the filter — it’s ready to use as soon as it’s dry.
