DCOE Throttle Bodies


AT Power's DCOE Throttle Bodies are a direct replacement for the Weber DCOE and Dellorto DHRLA carburettors.

Typically used in applications when converting or upgrading from DCOE and DHRLA carburettors to Electronic Fuel Injection (EFI), with the fixing bolt patterns matching those seen on the Weber DCOE DHRLA Carburettors, making these the ideal replacements for manifold mounted Carburettors.

Available in bore sizes of 36mm, 38mm, 40mm, 42mm, 45mm and 48mm and configurations of 2-Cylinder, 4-Cylinder, 6-Cylinder, V8 and V12, our DCOE Twin Throttle Bodies are supplied fully assembled ready to bolt on directly to standard DCOE bolt pattern manifolds.

They feature AT Power’s lightweight precision machined billet aluminium twin round housings design, with our unique patented ‘Shaftless’ technology and knife edged butterfly valves providing proven improved induction airflow speed and increased engine performance.

AT Power has developed a unique range of Direct-To-Head (Electronic Fuel Injection (EFI)) Twin Throttle Body systems, offering you multiple configurations and a range of optional extras to meet your specific engine tuning requirements.
