Banks Ram-Air Superiority.

Molded, streamlined filter housing. Lifetime, high-flow Banks Ram-Air filter. Flows more cool, dense ram-air into the engine. Limited Warranty (filter: Lifetime Limited Warranty).

Banks Ram-Air versus stock.
The factory air filter housing has little room for air to flow around the filter. The Banks Ram-Air housing has a larger inlet and ballistic-shaped nose, which encourage the reusable air filter to freely inhale for more power.
