"I love the powder-coated finish and overall quality. I think a minor mod will be necessary to modify the installation to compensate for the slightly different location of the SVT throttle body when installing on a Focus with the Jackson Racing Supercharger. Maybe K&N could supply an extra length of flex hose." —Coleman S from Los Alamos, NM bought a K&N 69 Series Typhoon Intake Systems for a 2004 Ford Focus.
