1300 max, you can go higher but only for a few seconds, 1100 is a safe sustained temp, but i would keep it below 1000 to make sure the engine lives a long happy life

where in Alberta are you located? your engine temp shouldn't be running that high, have you changed the exhaust yet? I would look into doing that, a nice mandrel bent 4" free flowing system should help, the AEM intake wont do crap considering the stock filter and unit will flow just as well, and provide cleaner air for a lot longer.... 100,000kms depending on how dusty the roads are you drive on, unless the filterminder is pulled down I wouldnt worry about changing it

Free up the exhaust and see if that helps, it should make a difference

MBRP or Magnaflow there should be plenty of places in edmonton to pick up an exhaust

actually 1350 is the max sustained temp. anything higher you shouldn't running it for long amount of time.

an exhaust will help you out though

I was just suggesting a very safe number to keep the EGT's at, 1350 is ok... but i personally wouldn't run it that hot for too long, LBZ have a history of cracking pistons...
