CARQUEST Ignition Modules are built by an ignition systems manufacturer with expertise in the entire vehicle spark system.

Product Features:

• CARQUEST Ignition Modules creates and refines the timing of the engine using various sensors and readings throughout the spark system in order to create an efficiently running engine.
• CARQUEST Ignition Modules use current and voltage limiting circuitry in order to prevent the ignition coil from over voltage/current. Over voltages can allow for coils to create excessive heat which can damage to the ignition module resulting in check eng
• CARQUEST Ignition Modules are 100% individually tested for all product functionalities including over voltage, timing and dwell.

The Premium CarQuest Vehicle Solutions line is designed for OE form, fit and function for both import and domestic vehicles. The A/C Pressure Relief Valve is used in the automotive air conditioning system to prevent unusual over-pressure that may cause damage to critical components within the system or to the system as a whole. By opening it’s valve when the system pressure exceeds the preset pressure levels and closing when the internal pressure decreases to the preset pressure levels, proper factory designated system pressures are maintained.
