      These small diameter spark plug tubes are engineered to minimize Rocker Arm to tube contact effectively. They serve as direct replacements for your current tubes, featuring Billet Aluminum ends and a 4130 steel body. The robust steel construction ensures durability, capable of withstanding Rocker Arm rubbing without denting or wearing. With an outer diameter of 1.180 inches, these tubes provide an additional .040 inches of clearance.  7.7" OVERALL LENGTH

      =====================================================

      Note: To use these tubes, a minor modification to the spark plug boot is necessary for it to fit into the tube. You’ll need 8 tubes for a complete set (16 for a dual-plugged head).
