NEW RELEASE: Additional valve guides for 2GR/2ZR/4G63 released

2025/08/30

We have added phosphor bronze valve guides for Toyota 2GR and 2ZR engines, as well as cast iron valve guides for Mitsubishi 4G63 engines to our lineup and commenced sales.

Phosphor bronze valve guides enhance thermal conductivity and strength, designed to prevent valve damage at high RPMs. Cast iron valve guides serve as an alternative to discontinued OEM valve guides, offering the same quality as genuine parts.
