Description
The Mishimoto MMOP-SPM22 is a purpose-built oil sandwich plate engineered specifically for M22 Stainless Steel Center Bolts, giving you a clean, lightweight way to route an external oil cooler into your vehicle’s oil system. Machined from 6061 aluminum and finished in silver, this plate is built to handle the demands of an added cooling circuit without adding unnecessary bulk to your engine bay. It’s a small but essential piece of hardware among the many components of an automobile engine that keep oil flow and temperature under control.
When you’re working on car engine parts and looking to expand your oil cooling setup, a sandwich plate like this one bridges the gap between your factory oil filter housing and an external cooler. The two 1/8-in NPT plugged ports give you flexibility to add sensors, gauges, or an oil feed line down the road, making this a versatile addition for anyone building out engine parts for a car that sees demanding use. As one of the more overlooked parts of a car engine, the sandwich plate plays a direct role in supporting healthy oil circulation and temperature management, which matters for the overall reliability of car engines and the automobile combustion process they rely on.
Vehicle Applications
This Mishimoto sandwich plate is designed to work with vehicles that use M22 Stainless Steel Center Bolts in their oil filter housing. Per Mishimoto’s technical notes, this sandwich plate was designed to only be used with an M22 Sandwich Plate Adapter, so it should be paired with that adapter for proper installation. No additional vehicle-specific application data was provided by the manufacturer beyond this M22 center bolt compatibility requirement.
