Speedmaster PCE409.1001 Air Cleaner Adapter 5-1/8" to 2-5/8"

The Speedmaster PCE409.1001 Air Cleaner Adapter steps down a 5-1/8" air cleaner base to a 2-5/8" carburetor neck, making it easy to fit a larger air cleaner onto a smaller carburetor stud or throttle body opening without custom fabrication. This adapter is a straightforward bolt-on solution designed to expand your air cleaner compatibility options and simplify your induction setup.

Ideal for street rods, muscle cars, and custom engine builds where mismatched air cleaner and carburetor dimensions are a common challenge, this Speedmaster adapter helps you achieve a clean, functional finish. Always verify your specific carburetor neck and air cleaner base dimensions before ordering to ensure proper fitment.
