Wiseco forged piston set for Honda B18C, B18A1/B1, B16A, B17A1 and B18 with B16A head. The set includes piston rings, piston pins, and pin clips. Set of four 81.50mm Wiseco forged alloy pistons with Armor Glide™ on the skirt which minimizes friction, improves wear resistance, and helps increase power; and Wiseco Armor Plating™ which reduces heat on the dome, reduces the effects of detonation, and creates a hard yet smooth surface for the rings to rest on. These pistons allow maximum flow around the valves, and feature a Piston Crown shape to promote Intake charge efficiency resulting in more added power. Wiseco pistons also feature a skirt profile to optimize squish or quench during the compression and combustion cycle resulting in resistance to detonation and pre-ignition, therefore increasing the engine’s longevity. Pistons are precision machined and have an excellent surface finish. The ring groove are CNC machined with tight tolerances. The included piston pins are high quality 9310 low carbon steel and the pin clips are Spirolox made from a chrome silicon material for excellent yield strength.
