Has anybody else had problems with their mishimoto thermostats? I bought their regular temp set hoping they would respond quick and they don't. Bought their 185 stats and the temp goes from 185-200 constantly. Ended up going back to 160 degree thermostats.

I have their low temp stats and they work amazing, keeping coolant around 175 and only 185-190 in the summer have yet to see anything above 190 even in heavy stop and go traffic with the AC on

with what ive seen in radiators and intercoolers, i wouldnt be surprised.... ive been using NAPA stuff on the last few engines.
X2. We won't even sell mishimito products anymore. Radiator in my race truck is less then a year old and already leaking. Had 2 customers now with products that only lasted 3 months.
