We have two systems. The Powrflo uses a stylish aluminum cover with a v-shaped opening with a formed stainless steel mesh. The other air intake systems are more elemental steel frames that hold on the air filter. The internal workings are the same for both styles.
We molded the inside of the K&N air filter with a venturi form that perfectly matches the machined aluminum velocity stack. This combination creates its smooth vortex air flow optimized for max power.
Yes, and it comes pre-oiled for immediate use. It retains the K&N warranty as well.
