Overall easy add on to get your OEM gauges to work. The cost was average, better than using an Aluminum adapter. Temperature reads 30-35 degrees to hot.

Installed temp sender in my 5.3 LS swap into my 1987 Monte Carlo SS. One wire sender works perfectly with factory gauge. No 12MM to 1/8"NPT adaptor necessary.
