Nice OEM replacement
Simple little sensor (just a switch) to replace my stock one on my FRS. I wanted a sensor with a more conventional thread which this one had. Works great!

bought this to replace the Onan part in a John Deere 316/316 lawn tractor because at low rpm the oil light came on, when we tested the engine with a pressure gauges it showed 11psi which is plenty for a sending unit that is supposed to read between 5-8 psi, installed this one and it works mint, not more flickering light at low rpm. recommend this.
