C-Tzu Intake Manifold Runner Control Motor for 2008–2013 Hyundai & Kia — Direct-Fit OE Replacement (28323-2G000)

The C-Tzu 911-922 intake manifold runner control motor is a direct-fit replacement actuator designed to restore proper intake runner positioning on compatible 2008–2013 Hyundai and Kia engines.

If your vehicle shows uneven idling, reduced low-end torque, or engine fault codes related to the intake manifold runner control, a worn or failed control motor can be the cause. This replacement unit is built to original-equipment (OE) standards and matches common part numbers 28323-2G000 and 28323-2G300, making it a practical swap for servicing Sonata, Santa Fe, Tucson, Sorento, Sportage, and Forte5 model years listed.

How does this motor re-establish normal engine behavior?

The intake manifold runner control motor repositions internal flaps that route incoming air to optimize combustion at different engine speeds. When the motor moves freely and accurately, the engine breathes as designed, improving throttle response and smoothing idle.

• Direct-fit replacement for 911-922, 28323-2G000, 28323-2G300 part numbers
• OE-standard design for proper alignment with rotary valve housings
• Restores correct intake flap movement to reduce hesitation or stalling
• Requires minimal adjustment when installed by a qualified technician

Which vehicles and years will this part fit?

This motor covers a range of Hyundai and Kia models from the late 2000s to early 2010s. Always verify the part number on your original motor before purchase to ensure compatibility.

• Hyundai: Sonata (2008–2010), Santa Fe (2010–2012), Tucson (2010–2013)
• Kia: Forte5 (2012–2013), Sorento (2011–2012), Sportage (2012–2013)
• Fits engines using rotary intake manifold control valves requiring the listed part numbers
• Check OEM number stamped on your old unit for a guaranteed match

What are the construction and durability features?

The 911-922 is manufactured from high-grade materials and assembled to meet factory tolerances. That combination yields a durable actuator intended to withstand typical engine bay conditions and deliver consistent performance over time.

• Robust housing materials resist heat and environmental exposure
• Precision gearing for accurate flap positioning and reduced play
• Designed to meet OE dimensional and electrical characteristics
• Lower long-term replacement frequency compared with cheaper alternatives

How does replacing this part affect drivability and efficiency?

A correctly functioning intake manifold runner control motor helps optimize airflow for different driving conditions, which can translate into improved low-speed torque, smoother acceleration, and more consistent engine performance. While results vary by vehicle and condition, fixing a faulty motor removes a common source of drivability complaints.

• Improves throttle response and reduces surging or rough idle
• Helps the engine achieve designed air/fuel distribution across RPM ranges
• May help clear related diagnostic trouble codes after replacement
• Supports better overall combustion behavior under varied loads

Who is this for? This C-Tzu 911-922 replacement motor is aimed at DIY mechanics, independent repair shops, and owners of Hyundai and Kia vehicles listed above who need a reliable, OE-standard replacement for a failing intake manifold runner control motor. If your vehicle matches the model years and part numbers and you want a durable, cost-effective actuator to restore normal intake runner operation, this unit is a practical choice. For proper installation and safety, follow factory service procedures or consult a qualified technician.
