Alloy water heated torquemaster inlet manifold hs4/6 hif38/4

Genuine mini Spares inlet manifold dyno tested and designed for our Stage one kit C-STN17. The single SU manifolds 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.Sales are 900-1000 per year as all tuners use this manifold so it must be good.
