A DISA valve is primarily there to extend or shorten the volume of the plenum. When your engine is running in lower RPMs, the valve is closed. This means that the excess air that ran into a closing valve can now take more time to make its way back.
Common Symptoms of DISA Valve Failure. 1 Poor fuel economy. 2 Rattling noise coming from the engine. 3 Loss of power at mid and high RPM’s. 4 Lack of low-end torque. 5 SES/CEL light and codes for running lean.
Professional installation is highly recommended. Please carefully compare the pictures or OE numbers to match your original parts before purchasing the product.
