For Oil Temp & Oil Pressure Gauge Sensor Mounting. Stri Oil Block Adapters (also called Sandwich Adapters) are made of high strength aircraft aluminum 6061 alloy material, cut and machined using the most advanced manufacturing technology, and are designed to withstand high temperatures without compromising durability and reliability.
The Stri Sandwich Adapters fit securely between the OEM oil filter mounting point and the oil filter allowing you to connect up to two 1/8" NPT sensors there. Typically users will connect an oil temperature and an oil pressure sensor here. If you choose to only connect one sensor, Stri includes a plug to block off the second port.
