This engine intake manifold flap motor is designed to match the fit, function and performance of the original equipment motor on specified vehicles. It is engineered to help optimize engine performance and efficiency by varying the length of the intake tract and managing air/fuel intake. When an original intake flap motor has failed from sticking or closed runners, seized linkages and shafts, or has simply worn out, this direct replacement motor can restore proper engine operation, fuel economy and emissions. This part is compatible with the following vehicles. Before purchasing, enter your vehicle trim in the garage tool to confirm fitment.
