Perfect Fit:
Includes stainless steel clamps for a leak-free seal and heavy-duty 5-Ply reinforced silicone coupling for strength.

Mandrel-bent Tubing:
Constructed of 3" mandrel-bent aluminum tubing then powder-coated wrinkle-black for heat and corrosion resistance. The smooth transition mandrel bends decrease turbulence which increases horsepower and torque while lowering EGT's. The high-temp wrinkle-black powder-coating insulates the tube from engine heat and protects the tube from corrosion.

aFe Badging:
Unique aluminum laser-cut aFe Power logo plate is welded-on for an aggressive style.
