Going into winter, a stock temp thermostat should be fine. Wahler is a good brand. As for fuel filters, the type is pretty well dictated by the fittings unless you want to do some plumbing. Bosch # is 71 005 with the outlet fitting, # 71 039 w/o the fitting. Get the fitting as well as copper crush washers for the banjo bolts. If you still have the o.e. turbo and intercooler you needn't try boosting over 12-14. Anything more and you'll be blowing hot air and increase the detonation.
