Intermotor® gives you more emission control system support than any brand in the industry. A complete product offering means complete coverage for all of your emission control needs. And that coverage comes with peace of mind: as a basic manufacturer, Intermotor® controls the process from start to finish, so you can always count on perfect performance, time after time.

“A complete product offering means complete coverage.”

EGR Valve | Designed To Go The Distance

Intermotor® EGR Valve

To reduce or eliminate the amount of smog-creating pollutants emitted during the combustion process, the EGR valve recirculates a portion of the exhaust back through the process. This results in cooler combustion temperatures, which eliminates the formation of NOx emissions that contribute to air pollution.

Every  Intermotor® EGR Valve is calibrated for precision performance. To ensure trouble-free operation, all Intermotor® EGR Valves must pass comprehensive quality testing, including computer-controlled bench testing for resistance, leakage, and response and flow rates.

EGR Position & EGR Pressure Sensors

The EGR Position sensor detects the movement and position of the EGR valve pintle. The EGR Pressure sensor detects exhaust gas flow through the EGR passage.

Intermotor® EGR sensors use the finest components and every sensor must pass meticulous quality control to assure that each EGR sensor’s voltage output measurement will always be accurate. Each sensor undergoes a rigorous end-of-line test validating output voltages to exacting specifications for reliable, trouble-free operation.

Utilizes custom BiCMOS IC technology, thin film laser trimming, and 2 sided ceramic circuit technology

Manufactured in our TS 14001 and ISO/TS 16949 Certified Facility

Idle Air Control Valve | IAC Valve

The idle air control (IAC) valve is located on the throttle body of fuel-injected engines, where it works with the vehicle’s ECU to electrically regulate airflow to the engine to ensure smooth idling. We manufacture Idle Air Control Valves at our ISO/ TS16949-certified facilities in Greenville, SC, and Reynosa, Mexico, respectively. A key aspect of the manufacturing process is the load testing, which makes sure each actuator delivers a greater force than actual load. 


  • Tested at greater than normal force to extend longevity
  • Anodized aluminum housing resists wear and tear from corrosion
IAC Valve

Precision-machined housing ensures proper air flow to engine as required by ECU during changing load requirements

Precision-machined solenoid components generate magnetic force to actuate plunger

Anodized aluminum housing resists corrosion better than regular passivation treatment

High-temp polyester coating on solenoid coil wire ensures proper function during cyclic exposure to elevated temperatures

Designed and Tested to Prevent Corrosion

The OE idle air control valves are prone to corrosion due to harsh environmental conditions. To make sure our SMP-manufactured IACs last, we give them an anodized coating that is thicker and more robust than the OE coating. As you can see from the results of our salt-fogging test below, our coating withstands corrosion better than the OE:
