Newer Sportsters use different valve sizes and configurations.\u003c\/p\u003e\n\u003ch3\u003eIs this an intake or exhaust valve?\u003c\/h3\u003e\n\u003cp\u003eThis is an intake valve. KPMI makes separate exhaust valves with the same Black Diamond process.\u003c\/p\u003e\n\u003ch3\u003eDo I need both intake and exhaust valves?\u003c\/h3\u003e\n\u003cp\u003eThat depends on your engine's condition.
