We currently have two types of adapters.

The Water Temperature Adapter has a 1/8"-NPT port and is made for cars with a 35 mm or 1-3/8" ID radiator hose. This includes most Nissans. We also have a new 29 mm or 1-1/8" adapter for many Hondas and the Miata.

The Oil Temperature Adapter is our most popular item. It is made for Japanese cars that all seem to have a 1/8"-BSP thread for their stock OP sending unit. This adapter screws into the block at the stock location and includes 1 female 1/8"-BSP port to retain the stock sending unit. It also includes the use of up to three 1/8"-NPT ports for gauges or turbo lines.
