The shorty design trims overall length by 3\/16 in to 3\/8 in to open up air gap between the plug boot and the header or exhaust manifold, which helps prevent burnt boots and dimpled header tubes and makes install easier in tight spaces. The copper core conducts better than platinum or iridium for a stronger spark and better heat dissipation, which lessens the chance of misfire under high combustion pressure. The plugs are gappable and use machine-rolled threads for precise engagement and torque retention. They are 14mm thread with a .460 in reach and tapered seat, heat range 6, preset to a .032 in gap, resistor type with a projected tip.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eType: HP Copper Core, shorty\u003c\/li\u003e\n\u003cli\u003eSold As: 4-pack\u003c\/li\u003e\n\u003cli\u003eThread: 14mm\u003c\/li\u003e\n\u003cli\u003eReach: .460 in\u003c\/li\u003e\n\u003cli\u003eSeat: Tapered\u003c\/li\u003e\n\u003cli\u003eHex Size: 5\/8 in\u003c\/li\u003e\n\u003cli\u003eHeat Range: 6\u003c\/li\u003e\n\u003cli\u003ePreset Gap: .032 in\u003c\/li\u003e\n\u003cli\u003eResistor: Yes\u003c\/li\u003e\n\u003cli\u003eProjected Tip: Yes\u003c\/li\u003e\n\u003cli\u003eGappable: Yes\u003c\/li\u003e\n\u003cli\u003ePart Number: 0576S-4\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003ch5\u003eHow many spark plugs come in the ACCEL 0576S-4?\u003c\/h5\u003e\n\u003cp\u003eFour (a 4-pack).\u003c\/p\u003e\n\u003ch5\u003eWhat are the thread, reach, and seat specs?\u003c\/h5\u003e\n\u003cp\u003e14mm thread, .460 in reach, tapered seat, with a 5\/8 in hex.\u003c\/p\u003e\n\u003ch5\u003eWhat is the heat range and gap?\u003c\/h5\u003e\n\u003cp\u003eHeat range 6, preset to a .032 in gap.
