Modified & jetted for Ford Zetec E/Duratec HE I4 2.0
Over the years it has become apparent that the fitment of 45DCOE carburettors to certain newer types of engine (such as Ford Zetec and Duratec) will result in a flat spot just off idle that no amount of calibration will eradicate.

Webcon have studied this characteristic in detail and have developed a very specific procedure to modify 3 or 4 progression hole models to 5 progression holes. This delivers the precise extra amount of mixture in the progression phase to overcome this flat spot resulting in a smoother more progressive transition from idle to main.

Burton Power is pleased to announce it now has stocks of these modified carburettors.
