If you are near the oil pump it can get quite hot, especially if your exhaust headers run under it, as the stock header does.

These are the parts I used available from newark.com
sensor
honeywell 103SR13A-2
magnet 102 mg11
I forgot to mention, I have a hot start problem related to this sensor. I know it's this sensor because Motec has an ocilloscope program built in to check sensors and my cam sensor drops almost to zero when hot. I was thinking it was the sensor or wiring harness, but maybe it's the magnet.
