Well since its summer and getting hotter by the day I was thinking about putting in a lower thermostat like maybee 170. what is the best one to put in and what is the stock one set at. also thinking about running tr6 plugs any sugestions.

The stock t-stat is a 195°F unit, there's no reason to install a lower temp unit; in fact without a tune things can get messed up even with a 180° unit (which is what I'm running here in Florida).[/align][/align]170° is way too low, the engine will run quite rich and your fuel economy will take a dump. With the 180° unit I've got I had to pull quite a bit of fuel from the tune to get the AFRs where they are supposed to be.[/align]

ok but what about the tr6 plugs are they worth getting

No stick with stock heat range plugs unless you are S/C or nitrous. 180* is minimum you want to go in any fuel injected car (using a MAF). I was running really rich at idle with both my car and my wifes casue they both have 180*. I fixed them by tuning it with sniper.

I'm sorry, I didn't have a clue as to what TR6 plugs were, I'm old and run Champions in everything we own; Champion single platinum stk #3401 IIRC in the Mustang.[/align][/align]In "googling" them I see that they are rather plain jane, conventional electrode plugs. These are great close-gapped for higher/high boost f/i applications as they can throw a big fat sparkif the coils have enough jizzto light 'em up, however for mildly modified n/a motors they offer nothing except an opportunity to change plugs more often as they'll be toast after 25k to 30k miles.[/align]
