The Banks Ram-Air Differential Cover is a game-changer in the cover industry. They took the extra mile when designing the 19269 Ram Air Cover by testing all the flat-back covers on the market to determine where they were falling short and how Banks could improve the design. This is what they came up with, the new Ram Air Differential Cover cools 5 Times Better than flat-backs.
 
 Banks Power Part Number: 19249, 19259, 19269
 
In-fact, they found that other flat-back differential covers didn't cool as well as advertised and suffer from poor fluid dynamics and as a result actually reduce your fuel economy and efficiency.
