Rein Intake Manifold Adjusting Unit DISA Valve

The Rein Intake Manifold Adjusting Unit, also called a DISA valve, intake manifold runner control valve or intake air adjustment unit, helps the engine perform across the rev range. It adjusts the intake manifold airflow path as engine speed changes. This gives the engine strong low-end torque at low RPM and more top-end power at high RPM.

Key Features:

• Controls the intake manifold path to balance low-RPM torque and high-RPM power
• Replaces a worn or failed DISA valve, which can cause reduced power, rough running or intake-related drivability problems
• Made by Rein Automotive as a quality aftermarket replacement for European applications
• Designed to restore intake manifold adjustment to its original operating function

Installing a new Rein adjusting unit helps restore the engine's intended power delivery and responsiveness. Select the part number that matches your application from the options listed on this page.
