AEM - Warranty AEM - About


  • Useful for tuning when used with wideband UEGO sensor
  • Installs in exhaust stream
  • Kit includes thermocouple, wiring harness, compression mount, and heat shrink tubing
  • Comes with detailed instructions
  • Limited 1-year warranty

This thermocouple installs in the exhaust stream, preferably 1-2” from the exhaust port, 2-3” before the turbine inlet, or in the header collector, and supplies exhaust gas temperature information to the X-WiFi Wideband UEGO Controller and EGT Monitor. This information, when used along with the data from the wideband UEGO sensor, can be used to tune an engine for best power and prevent lean conditions which could cause engine damage.

The kit includes the thermocouple, wiring harness, compression mount, heat shrink tubing, and installation instructions. It’s backed by a limited 1-year warranty against defects in materials and workmanship.

John Concialdi and Bob Sullivan co founded AEM in 1987 as a tuning performance shop in Compton California. Both men had extensive technical backgrounds in engines and engine airflow, and in a short time AEM became the go-to company for performance modifications. By 1993, when the company relocated to Gardena California, it had become commonplace to see cars wearing the bright yellow AEM logo winning races. AEM tirelessly dyno tested and worked closely with racers and auto manufacturers in an effort to understand intake energy dynamics. This resulted in the sale of their first air intake kit in 1994. AEM can boast a number of firsts and unique products: They’re the first manufacturer to make an intake system with specific tube lengths and diameters to take advantage of pressure waves in the inlet tract; they developed the first dual chamber intake kit; they designed an air bypass valve to prevent hydro-lock should the air filter ingest water; and they created one of the first hybrid intake systems for modified cars. AEM continues to create innovative products to help you get more power from your car.
