Engine Alpha Dragon IV ‘injector’ backplate janvier 9, 2020 by Chris Leave a Comment Alpha Plus Engines have introduced the new ‘injector’ backplate. Designed to be use with the Dragon III, IV, GT, and GT-R range of engines, the backplate helps the fuel flow from the crankcase to the combustion chamber by pulsing fuel through the backplate in a more effective way. The result is a much quicker return to idle as well as an improvement of fuel efficiency. Shopping!
