Description
Upgrading from a 2-barrel to a 4-barrel carburetor doesn’t mean replacing your entire intake manifold—this Mr. Gasket adapter bridges that gap with a straightforward, bolt-on solution. By stepping up to a square-bore 4-barrel carb, you’ll unlock measurable gains in airflow and fuel delivery, translating directly to improved throttle response and power output. The kit includes all necessary hardware, so installation is a single-afternoon job with no fabrication required.
