I have a 99 gtp. I have a k&n cold air intake, 3" bolt in down pipe with cat bolted to a stock exhaust, 180 t-stat, 3.5 pulley, autolite 104 spark pulgs. i just had the thermostat, pulley, and plugs put in yesterday. The car was running 2 notches below the large notch that is in the middle of 160 and 210 on the oil temp guage. As it later tonight it was running 3 notches away from 210, it never gets that hot. I read in the reviews on the zzperformance website that the gaskets that are sent with the thermostats are garbage. Anybody have any suggestions as to what the problem may be?
