Twin Housing Throttle Bodies | Direct-to-Head Shaftless ITBs

AT Power’s Direct-to-Head (DTH) twin housing throttle bodies are port-matched to the OEM intake ports of a wide range of engine variants and bolt directly to the cylinder head intake face - no manifold, no adapters. Each unit pairs two intakes in a single lightweight twin oval housing, machined from aerospace-grade billet aluminium.

Shaftless inside

Like every AT Power throttle, twin housings carry our patented Shaftless technology with knife-edged butterfly blades: nothing crosses the bore, so induction airflow speed rises and engine response sharpens measurably over shafted designs. Supplied fully assembled and ready to bolt on - proven on engines like the Ford Cosworth YB (45mm), Cosworth YB 52mm for ported heads and Ford Duratec 2.0/2.3L.

Configure it your way

Options include billet throttle linkages or Drive-By-Wire (DBW), rotary contact or Hall-effect contactless TPS mounting kits, SLS 3D-printed extension tubes, billet ram pipes in a choice of lengths, one-piece billet fuel rails with injector brackets, vacuum take-off fittings and 20+ anodised colours - plus injectors, air filtration, motorsport cables, tuning aids, fuel pressure regulators and ECUs to complete the system.
