aFe Powers Charge Pipes are constructed from mandrel-bent aluminum tubing for maximum flow then, powder-coated for a nice finish. The high-temp wrinkle-black powder-coating also insulates the tubes from engine heat and protects the tube from corrosion. The smooth transitional bends decrease turbulence and minimize loss pressure to maximize horsepower and torque. Also included is one 1/8 NPT port on each tube which is provided for a sensor or water-methanol injection. Each set of aFe Charge Pipes comes with a unique laser-cut aFe Power logo plate attached for an aggressive style.
