Kia Optima CRDI Swirl Flap Delete Plug Set

This Kia Optima Swirl Flap Delete Plug Set is intended for compatible 1.6 CRDi and 1.7 CRDi intake manifolds where the original swirl flap mechanism is being removed.

Swirl flaps are used within the intake system to influence airflow under specific engine operating conditions. Over time, the mechanism may develop wear, play or faults depending on the condition and configuration of the intake system.

These delete plugs are used to seal the corresponding openings after removal of the original swirl flap components as part of a properly planned intake-system modification.

ECU software modification is required.

Mechanical removal of the swirl flap system may require the corresponding control function to be disabled in the vehicle's engine-management software.

Removing the actuator or control valve without addressing the ECU strategy may result in diagnostic fault codes or incorrect engine-management behaviour.

ECU software changes should be carried out by an experienced automotive calibration specialist.

Professional installation is strongly recommended.

Installation involves removal of the intake manifold and modification of the original swirl flap system.

The intake manifold should be inspected for contamination, wear, damage or other issues while removed from the vehicle.

After installation, verify that the intake system is correctly sealed and that the ECU software has been configured appropriately.
