Description

Allstar Performance water neck spacers fit between intake manifold and water neck. They're designed to move the thermostat and housing up so they are higher than the intake manifold. The increased thermostat height is useful for cars with radiators higher than the intake manifold and these spacers provide up to four connection options for temperature senders or additional water lines. Most water neck spacers feature an O-ring seal on one side eliminating the need for a gasket.

Additional Information

Spacer has 4 1/2 NPT ports with plugs. Replacement Part ALL99353 Base O-Ring
