I'm wondering what is the best setup for the most accurate readings with out major surgery. I want to run oil pressure and oil temperature gauges. i have seen a few oil press. setups that take the place of the stock sending unit, but i wonder would a aftermarket gauge be better? I made the mistake of sourcing oil temp. from the oil drain plug on a previous car. the readings were too slow and didn't show the hottest the oil got and before i new it, i was baking my oil. Would the product from moss motors that installs between the oil filter and housing be a good choice? http://www.miatamania.com/Shop/ViewProducts.aspx?PlateIndexID=53760 does anyone else have experince with this? or a different setup that works? thanks for any input.
