Buying advice

When choosing an intake manifold spacer, consider the material (phenolic is best for heat reduction), thickness (affects clearance), and compatibility with your engine and intake setup. Thicker spacers provide better insulation but may require a hood scoop. Also check bolt length as spacers often require longer bolts. Always verify that the gasket ports match your intake and head configuration.
