sensor under plenum?

Just pulled my plenum off my '89 LB9 (305TPI) and noticed a sensor attached to the bottom. What is this? Looks like it may be a temp sensor of some kind.

Looks can be deceiving.

However, in this case, they're not. That's exactly what you have under there. Want to guess what is senses?

Give that man a cigar!

On TPI motors I've often relocated it over to the air filter box- it gets heat-soaked real easy in the middle of the than aluminum oven. I don't actually take it out- I just buy another one, install it over near the air filter and extend the wires over to it. Doesn't make any more power but the engine ran more consistently hot vs. cold.

Thanks Damon, Air filter box is gone in place of open K&N, but I was just wondering
