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 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”.

    Fit perfectly, installed oil gauge sensor. This enabled me to not mess with the dash oil light, so adding an oil pressure gauge is nice to actually see the oil pressure. Install short and sweet. No oil leaks either.

    I called these guys to make sure I purchased the correct one for my 71 chevelle. I talked to Nick, he was very helpful and courteous and made sure the right one was sent. It is a very nice part, I was able to get both my oil temp and oil pressure senders/ gauges hooked up with it. Very happy with the quality and customer service, would not hesitate to do business with these guys in the future. Thanks!
