Does anyone know of an inexpensive way to meter intercooler In/Out air temp?

So far the only thing I've found is an Autometer gauge and temp sensor set up that runs around $250. (not worth it in my opinion.)

I know there's got to be a less expensive way using some modified gauge and meter designed or another application. (i.e. like using a welding tank regulator control valve for a boost control regulator)

Thanks in advance!
