Speedmaster PCE409.1002 Air Cleaner Adapter 5 1/8" to 3 1/16"

The Speedmaster PCE409.1002 is an air cleaner adapter designed to connect and transition between two different diameter air intake sizes: 5 1/8" and 3 1/16". This adapter is essential for automotive and small engine applications where custom or modified intake manifolds require stepped diameter connections. The precision-engineered design ensures a secure fit and proper air flow transition.

This adapter is ideal for engine builders, performance enthusiasts, and mechanics who are assembling or modifying intake systems with mismatched diameter ports. The tapered construction allows smooth airflow transition between the larger 5 1/8" opening and the smaller 3 1/16" opening, maintaining intake efficiency. Compatible with various engine builds and carburetor configurations, this adapter provides a reliable solution for intake manifold compatibility issues and custom engine projects.
