High-Performance Alloy Water Heated Torquemaster Inlet Manifold HS4/6 HIF38/4 - Durable Replacement for Industrial & Marine Engines - Perfect for Boats, Trucks, and Heavy Equipment

Genuine Mini Spares inlet manifold. The single SU manifold is developed to give maximum airflow and gas speed, yet fit all engines even if the standard air cleaner set-up is used. It has 1/2" pipe through it for heating with water and the as-cast finish provides maximum fuel atomization.


C-AHT770 takes 1.5" AND 1.75"carbs. Medium size port runners suit all small bore engines, and large bore engines up to fast road spec (dependent on head intake port size).

The plug 5/8UNF (supplied with manifold) should be thread locked into the manifold, with care taken not to wind all the way down.
