*** IN STOCK SHIPS TODAY *** From time to time headers get swapped, combinations change, parts get lost and when you think we just gotta connect these thermo-couples up and we will fire the motor....... Wait some of the thermo-couples have brass ferrules some don't. Well friends these are those little parts that get lost. Not to fear RBS carries a full supply of 2-piece brass ferrules for 1/4" EGT RacePak probes.
These ferrules slide ont the thermo-couple and seal the thermo-couple to the header so the racer gets an accurate EGT reading to their computer. Ferrules are sold each and include both parts as shown in the picture.
