Does this kit require tuning after installation?
▾
No, this mechanical fix doesn’t require ECU tuning. Since it removes failing flaps without altering airflow sensors, the engine runs normally without error codes in most cases.
How difficult is the installation?
▾
Installation requires removing the intake manifold, so moderate mechanical experience is needed. Expect 2–4 hours depending on vehicle access. Basic hand tools are sufficient for the job.
Is this a performance upgrade?
▾
No, this is a reliability fix, not a performance part. It prevents damage from broken flaps but doesn’t increase power. Some report smoother idle after eliminating flap rattles.
