I have a spare temp sensor & gauge, pictures on my thread (LC-1 & charge temp), the gauge reads -20 to 70 deg, & in 0.1 increments, measures temp every .5sec compaired it with a lazer temp gun, & was just about the same,
Easy to wire up ign live & earth.
Comes with gauge, temp probe (sevral mtrs long)
ideal for monitoring intake,inlet temps, or else you can think of.
