Description

The Flyin' Miata radiator cap is an exclusive product designed with a silicone seal for longevity and an anodized finish with a laser-engraved logo. It is available in 16 psi or 20 psi versions. The 16 psi version is recommended for most cars running at least 30% antifreeze, while the 20 psi version is for systems running more water to raise the boiling point.
