P2R Weld-In Freeze Plug Kit for Honda & Acura J-Series Cylinder Heads

P2R weld-in freeze plugs are engineered for Honda and Acura J-Series cylinder heads, including J30, J32, J35, and J37 variants that use factory pressed-in freeze plugs.

Each plug is CNC-machined from 6061 billet aluminum for superior strength and thermal stability. The design seats the plug below the camshaft lobes when welded, ensuring full clearance and a secure, permanent seal.

This complete kit includes four plugs, providing a robust solution for engines experiencing freeze plug failure under high boost pressure. Ideal for high-performance and forced-induction J-Series builds.
