IDF style
IDF style throttle bodies are compact, downdraft, two barrel units equally at home on a V8 or VW and Porsche four cylinder, air cooled engines. They are available in 40, 45, 48, and 50 mm bore sizes. Borla Induction machines all four of the injector pockets during manufacture, supplying plugs for the unwanted pockets and removing the unwanted rail brackets (on 1999 models) at the time of ordering. Air horns for the IDF style throttle bodies are available in lengths from 35 mm to 100 mm.
