Overview

This kit removes the Idle Air Assist valve, which is typically mounted on the radiator inlet or intake manifold. The valve's function is to raise idle during cold starts for faster engine warm-up, a task that a properly functioning IACV already handles.

Show original supplier description

This valve, commonly found on the radiator inlet or intake manifold with hoses connecting to the intake manifold and piping, serves to increase idle speed during cold starts for quicker warm-up. Our testing at K-Tuned has confirmed that this valve can be safely removed, as the Idle Air Control Valve (IACV) performs the same function effectively. This is particularly beneficial for owners of RSX, TSX, 8th Gen Civic, and EP3 models, where the Idle Air Assist Valve can often obstruct the installation of upgraded fuel rails. The kit includes necessary plugs for the intake manifold port and the coolant port on the radiator inlet or intake manifold, ensuring a clean and professional installation.
