GlowShift’s Chevrolet Small Block 305/350 Oil Filter Sandwich Adapter allows you to install up to (4) 1/8-27 NPT oil pressure or oil temperature sensors to your small-block engine’s oil filter to see how efficiently it is performing. This 2WD Chevy Small-Block oil filter sandwich adapter easily installs in between the engine and oil filter using the included 13/16-16 thread fitting for a secure fit. Crafted from aluminum, this oil filter adapter eliminates the need to drill into the oil pan and remove any stock sensors that are being used. If you are not using all of the ports on the oil filter sandwich adapter, you can easily close them using the included flush mount port plug threads. The included dual O-ring gasket allows for a leak-free seal between the engine and oil filter.

GlowShift includes step-by-step installation instructions, free lifetime technical support and a one year limited warranty with each purchase.

Note: This Chevy Small-Block Oil Filter Sandwich Adapter is only compatible if the gasket diameter is a minimum of 3" and maximum of 4”.
