godfather18 Posted October 27, 2006 Share Posted October 27, 2006 Im thinking about doing a couple of upgrades and need some input. 1)Torque master spark plugs, saw these on L-tunedparts.com and need some advice if they would benefit me in anyway. 2)Hyper ground system, saw this as well and wanted to see if upgrading the grounds for my engine would make a difference. 3)TRD thermostat, saw this and wanted to know if this really makes the engine run a little cooler, it said 10 to 15 degrees cooler.
