This spacer is ideal for those modifying classic muscle cars, turbocharged street machines, or custom hot rods.

Constructed with precision engineering, the 1/2 inch x 5 1/8 inch spacer provides the necessary separation to maintain proper airflow while preserving valuable engine bay space. The lightweight design, weighing just 0.18 lbs, ensures minimal impact on overall engine weight while maintaining structural integrity under thermal cycling and vibration. This adapter integrates seamlessly into existing intake systems without requiring modifications to neighboring components.

Professional mechanics and dedicated gearheads will appreciate the ease of installation and compatibility with various carburetor air cleaner mounting systems. The 5 1/8-inch height is particularly beneficial when working with high-rise intake manifolds or aftermarket carburetors. This product is a must-have for anyone looking to enhance their engine's performance and efficiency.
