Features: Six times harder than platinum, iridium withstands temperatures up to 4,000°F. Because the iridium electrodes of these plugs can be shrunk to only 0.4mm, voltage requirements decrease while firing performance improves. 360° laser welding of...
Features: Cast Replica – Cast piston in original OE form. All pistons are heat treated with a T-5 hardening and tempering cycle. All piston skirts are coated with a high-tech Molybdenum Disulphite coating for faster break-in time and increased piston...
