Yeah, run a long pipe to it. Our sensor uses a 1/8 NPT fitting to attach to the pipe, which is about 40 cm long (go longer if you're scared). If you're using a more conventional 3 bar MAP sensor, then you'll need a bit of rubber hose from the end of your pipe to the sensor. The reason it works without frying the sensor is that there is no continuous flow between the headers and the sensor. Air/exhaust is a pretty good insulator of heat and thin wall stainless tube won't conduct far before the heat is rejected to the surrounding air. Of course, if you have a leak at the sensor end of the tube, you'll probably fry the sensor pretty quickly, so make sure there isn't one.
We've been using the same EMAP sensor for over 2 years now and it hasn't failed yet. Not promises of course, but the idea seems to work fine.
