The JRP EGT v3 sensors have had improvements made to their design in a few important areas, first is we have moved to a 2520 stainless steel probe body and increased the thickness of the probe itself from 3mm to 4mm which will better protect the induction point inside the probe for better durability and longevity. The probe design itself has also been improved, it now tapers down from the top to tip. Just like the v2 EGT sensors the v3 is using multi-core wire, one of the major killers of cheaper EGT sensors supplied with a lot of aftermarket gauges out there is them using single core wire, the JRP EGT v3 probe is using 16 AWG high quality multi core wire from the induction point back to the Deutsch connector. The induction point on the v3’s are shielded to ensure no external grounds can make it into the sensors to cause inaccurate readings from any leaky earths that may be lurking in the vehicle. The response rates of the v3’s has also been improved slightly over our v2’s as well, not that our v2’s are slow to begin with, one of the most common bits of positive feedback we receive on our v2 sensors is how responsive they are, but we have managed to improve on that again with our v3’s. Accuracy is of course paramount, and just like our v2’s the v3’s are incredibly accurate and have been reference tested by our workshop customers to fall within 1% of their dyno EGT setups.
