  • Q: Defi probe length  Slowpoke842 8 months ago


    Is this photo accurate? The probe appears to be too deep for most header tubes and much longer than my original BF / Link sensor? Is there another part # for short insertion?

    • A: The photo is pretty zoomed in for the most part to show detail. The probe won't be too long. It is just what usually comes in the defi exhaust temp sensors.

  • Q: Gauge stopped reading  awdturbowrx 3 years ago


    I think my EGT sensor quit working on me. Would this be the replacement for my Defi gauge? This is the part that goes into the header?

    • A: This replacement EGT sensor is compatible with the Advance, Racer and Link series gauges. This sensor installs in the exhaust system, and the header is the most common location.

  • Q: Which part?   2005 sti 3 years ago


    I have the 3 pod set up with all three Defi Guages(boost press,oil press,Ext temp) online the boost works. The others light up but have a constant flashing light with no readings. I see the cable for the Ext. Temp was broke off just behide the sensor and don't see the oil temp wire or sensor at all, what will I need to order to get them working again? 2005 sti

    • A: This part would work great for a replacement on the exhaust gauge and as for the oil temp wire you would either have to order a whole new gauge or contact defi cause we do not sell one.
