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.

*Tests were performed on the same flow bench under the same conditions, with the MAF sensor installed.
