Holley High Flow Power Valve 2.5 Hg Single Stage HOL125-25
* Includes Gasket For Valve
If you have a carb older than 92 and suspect a blown power valve (due to extreme backfire) use this simple test. TEST: At idle turn your idle mixture screws (found on the side of the metering block) all the way in. If your engine dies the power valve is not blown.
