Description

The Interstate-McBee M-4937308 is an OE-style piston cooling nozzle, also known as an oil squirter. It is designed as a direct replacement for the factory jet that sprays oil onto the underside of the piston crown to control temperature and reduce wear. This nozzle is built with quality materials by Interstate-McBee for durability in high-temperature, high-pressure service.

This nozzle maintains OE-equivalent performance, ensuring proper piston cooling and lubrication under load. It is sold individually, and six are required per engine (one per cylinder). Replacement is recommended during rebuilds or when a nozzle is clogged or damaged to ensure even cooling across all cylinders.
