Closed Tip EGT Probe Red Avenger



SKU: EGT-Prb-3018 Categories: ,


Measure your exhaust gas temperature per bank or per cylinder with a longer lasting, closed tip EGT probe, a K type thermocouple with an 8 foot lead. The open tip probe reads slightly faster than a closed tip EGT Probe, but tends to wear faster in extreme heat conditions.  Compatible with CANEGT or Innovate TC-4, LMA-3, or DL-32, and many other temperature devices. Diameter is 3/16″.

The ideal mounting location for your closed tip egt probe will be high in the exhaust runner in a consistent position cylinder-to-cylinder, normally 1 to 3 inches from the header mounting flange (approximately 6 to 9 inches from the actual in-cylinder burn) and at a common depth in the flow path.  Other acceptable locations are in the collector, where temp data for the bank is averaged, or in a single exhaust runner, positioned in the same way you’d place it for a multi-channel setup.

‘Multi-channel EGT systems add another dimension. “Generally speaking, one looks for consistency between cylinders, because any noticeable variation means that the cylinder that is out of step with the rest has some sort of problem like a flow blockage, an inner chamber variation, or a cam lobe shift that is causing the odd EGT. “On an EFI engine, a simple fuel rate change to the ‘out of step’ cylinder will aid in detecting the cause of the variation by either confirming or rejecting fuel (and air) flow variation as the cause.”

Can I use this EGT probe with my ECU?

  • You must use an EGT amplifier with this probe such as the CAN-EGT or Innovate TC-4

How exactly do I install this probe?

  • It needs a compression fitting. We have several styles, sold separately.

Can I cut the leads if they are too long?

  • We do not recommend this as it is difficult to cut the leads cleanly. It is better to just coil them out of the way.

Should I use this probe or the “Black Stinger” version?

  • We recommend the Red Avenger probe for use if you are running it upstream of the turbo. While it is unlikely that a Black Stinger’s open tip will break off, this is a remote possibility and could damage the turbo. We have never heard of the end breaking off on a Red Avenger.
  • If you do not have a turbo, or are measuring post-turbine temperatures, the Black Stinger probes will respond a bit faster.

    Q Which is better for egt on a turbo application ?? Open or closed tip?
    Asked by Jason McKechnie

    We generally recommend the closed tip design for turbo builds. While the odds of the tip coming off an open tip probe and damaging your turbine are very low, it is possible for this to happen. Closed tip probes do not have this potential failure mode.
