Standard Ignition Engine Intake Manifold Runner Solenoid P/N:RCS103
Keep your intake manifold's runner valves switching on cue with the Standard Ignition Engine Intake Manifold Runner Solenoid RCS105. It installs as a direct-fit replacement for many listed Mazda applications, among them the 2004-2013 Mazda 3 2.0L / 2.5L, 2012-2014 Mazda 5 2.5L and 2009-2013 Mazda 6 2.5L.
Signs the runner solenoid may need attention include a check engine light with an intake manifold runner control trouble code and sluggish low- or high-rpm response. Because other components can set the same codes, diagnose the cause before replacing. If a failed runner solenoid is behind the fault, the RCS105 replaces it on the listed applications. See the "Vehicles it fits" section for the full fitment list.
What does the Standard Ignition RCS105 do?
It controls engine vacuum to the intake manifold runner control actuator, which opens and closes the intake runner valves to match metered airflow to engine speed.
Will this fit my 2009-2013 Mazda 6 2.5L?
Yes — the RCS105 is listed as a direct-fit replacement for the 2009-2013 Mazda 6 with the L4-2.5L engine. Check the "Vehicles it fits" section to confirm your exact vehicle.
What are the signs this solenoid may need replacing?
A check engine light with an intake manifold runner control trouble code, plus reduced low- or high-rpm response, can point to it. Diagnose the cause first, since other parts can trigger the same codes.
Does it fit the 2.0L and 2.5L engines?
Yes — it's listed for the 2004-2013 Mazda 3 2.0L / 2.5L and the L4-2.5L in the 2012-2014 Mazda 5 2.5L. Confirm your vehicle in the "Vehicles it fits" section.
Should I diagnose the system before replacing the solenoid?
Yes — other components can set the same intake manifold runner control codes, so confirm the runner solenoid is the cause before replacing it.
