• Valve Type: Exhaust

Ideal for engines that see elevated exhaust gas temperatures during extended boost or competition, designed to maintain strength and sealing under long sessions and repeated heat cycles. Choose Inconel for turbocharged or endurance builds that see sustained high EGT or prolonged track use - it offers greater hot strength than stainless in these conditions.

Compatible with various Honda J35 V6 engine variants including J35A1, J35A4, J35A6, J35A7, J35A9, J35Y1, J35Y6, J35Z1, J35Z2, J35Z4, and J35Z8 found in Honda Odyssey, Pilot, Ridgeline, and Acura MDX, TL, and RL models. Professional installation recommended with proper valve seat cutting, clearance measurements, and spring pressure verification.
