Piston cooling jet kit (contains two cooling jet assemblies)
Twin Cam style engines with strokes longer than stock, require special piston cooling jets to avoid contact with pistons at the bottom of the stroke. S&S cooling jets provide an extra .150" of clearance between the jet and piston skirt compared with stock jets. These special jets are included in the S&S 107" and 116" Sidewinder and Hot Set Up kits. S&S piston cooling jets are sold in kits.
