Do I need to clean or replace this filter regularly?

Unlike disposable filters, this one is washable and reusable. You'll rinse it out periodically with water, let it dry completely, then reinstall. Extends the life of the filter significantly compared to paper elements.

Will this affect my fuel economy?

High-flow filters improve air intake efficiency. You may see slight gains in throttle response, but fuel economy impact is negligible — it's more noticeable in how the engine feels when you step on it.

Does this come with any adhesive or fasteners?

The filter itself uses the factory air box mounting — no additional hardware needed. Install takes minutes with basic hand tools and no special preparation.
