Standard Motor Idle Air Control Valves

Standard Motor Products replacement idle air control valves help you get maximum fuel efficiency and power from your engine. A properly operating idle air control valve is an essential component to helping your vehicle run flawlessly. These valves are often referred to as idle air control or IAC valves (GM), automatic idle speed or AIS valves (DCX), and throttle air bypass solenoid or AIR valves (Ford). These idle air control valves are used on both throttle body and multi-port fuel injected engines to regulate idle speed. The IAC valves open a small bypass circuit that allows air to flow around the throttle. Increasing the volume of air that's allowed to bypass the throttle increases idle speed. The engine's computer controls the IAC valves, if idle speed is out of range, and commands the IAC valves to either increase or decrease the bypass airflow. Replace your vehicle's worn or malfunctioning idle air control valve with these reliable Standard Motor Products replacement IAC valves.

Standard Motor Fuel Injector O-Rings

Replace your worn, cracked, or damaged fuel injector O-rings with Standard Motor Products. Your vehicle's fuel injectors operate under extreme pressures and are fitted with several O-rings to prevent leakage of fuel into hot engine compartments. The operating conditions are tough on sealing materials, and O-rings must be capable of sealing from as low as -40 degrees C to as high as +150 degrees C and be highly resistant to aggressive automotive fuels. The consequence of O-ring failure could be catastrophic, so trust your engine to Standard Motor Products O-rings.

JET Powr-Flo Throttle Body Spacers

These JET Powr-Flo throttle body spacers use aerospace engineering combined with years of experience. The exceptional design of the bore causes the incoming airflow to actually smooth out and speed up. This creates a type of compacted air-charge that enters through the throttle body and builds pressure in the combustion chamber. This will result in an extensive gain in the midrange power band and an overall increase in fuel economy.
