The Mishimoto Thermostatic Oil Sandwich Plate Gold is a premium component engineered to provide optimal oil temperature control for high-performance and daily-driven vehicles. Crafted from high-quality, CNC-machined billet aluminum, this sandwich plate inserts seamlessly between the engine block and the oil filter. Its standout feature is the built-in internal thermostat, which remains closed until the oil reaches its optimal operating temperature, allowing the engine to warm up efficiently before routing oil to an external cooler. The striking gold anodized finish not only provides exceptional corrosion resistance against harsh engine bay elements but also adds a visually distinct, high-end look to the vehicle’s powertrain layout.
Engine protection is the core benefit delivered by the Mishimoto Thermostatic Oil Sandwich Plate Gold. By regulating oil flow through a built-in 185-degree Fahrenheit thermostat, it prevents the engine oil from over-cooling during normal highway cruising or in colder climates, which can cause increased friction and premature component wear. When the oil temperature rises under spirited driving or track conditions, the thermostat opens completely to direct the fluid through the cooling lines, maintaining ideal lubrication properties. This dual-action design eliminates the risk of thermal shock and ensures that the engine consistently operates within its safest, most efficient thermal window.
Installation flexibility makes the Mishimoto Thermostatic Oil Sandwich Plate Gold a highly versatile upgrade for automotive enthusiasts. It features standard ports that accept regular lines and fittings, alongside additional ports designed for attaching aftermarket oil temperature or oil pressure sensors directly into the oil stream. The kit comes equipped with a heavy-duty rubber O-ring to guarantee a leak-free seal against the engine block under extreme pressure conditions. By combining reliable thermal regulation, robust structural integrity, and an eye-catching aesthetic, this component serves as a crucial line of defense for maximizing engine longevity and performance.

Mishimoto Oil Filter Sandwich Plate

An angled, close-up photograph displays a gold-anodized aluminum oil filter sandwich plate manufactured by Mishimoto, whose black logo is printed diagonally across the flat top surface. The block features a circular recessed well on its top right side with a central bore for mounting between an engine block and an oil filter. Its rectangular front face contains two large, internally threaded ports for oil line connections, flanking a smaller black hex-drive plug in the center. A large, black hex-headed bolt or sensor plug is installed into the right side of the unit, and the entire component is isolated against a plain, solid white background.

A detailed side-view shot captures a metallic component with a smooth, gold-anodized finish. The object has a vertical, rectangular profile with rounded corners at the top and a flat bottom edge. Positioned precisely in the center of the face is a black, recessed hexagonal socket set screw, intended for securing or adjusting the hardware. On the left edge, a slight sliver of a black circular inner lining or ring is visible, indicating that this may be a mounting collar, shaft clamp, or a similar mechanical fixture. The background is a stark, seamless white, making the textured metallic gold surface stand out clearly.

A close-up studio shot shows a gold-anodized aluminum oil filter sandwich plate adapter manufactured by Mishimoto. The block features the black stylized Mishimoto logo boldly printed across its smooth top surface. A large, circular recess with a central mounting bore dominates the upper section, designed to interface with an engine’s oil filter housing. On the front face, two large, threaded fluid ports sit side by side to connect external oil lines, separated by a small black Allen head screw in the center. A black hex-shaped component or thermostat assembly protrudes from the right side of the unit, all set against a plain white background.
Mishimoto Gold-Anodized Component in Custom Tin Case

An overhead full shot displays a small gold-anodized metal component nestled inside a rectangular silver-colored tin container with a hinged lid. The box is open, revealing its lid on the left and the lower compartment on the right. The lid’s interior has an inner rim that mirrors its outer shape. The right compartment features a dark gray foam insert with a textured surface, tailored to snugly fit the component. The gold piece is rectangular at its base and arches into a semi-circle at the top. Near the curved top, there’s a circular opening, surrounded by an indention that curves from the upper right, around the circle, to the bottom left. The bottom edge of the gold component is stamped with the brand name ‘MISHIMOTO’ in black, italicized capital letters. A small black node extends from the right side of the component, fitting into a recess in the foam insert.
