You can try to swap injectors to see if the low temperature follows the injector but I suspect these readings will become meaningful at higher power settings. Monitor these readings carefully during early flight testing.

You can make your own by using spray adhesive (3M #90) to bond heavy duty cooking aluminum foil to class cloth and then bonding that to your cowling. Seal the edges with RTV.
