IGNITION, FUEL SYSTEMS AND ELECTRICAL PERFORMANCE THROTTLE BODIES FOR VEHICLE EQUIPPED WITH ELECTRONIC THROTTLE CONTROL (ETC) Electronic throttle control was introduced on the Mustang in 2005. Its introduction has made attention to detail and setup of replacement throttle bodies even more critical than in the past. Ford Racing throttle bodies are tested and engineered to give the customer trouble-free operation and are set up from the factory ready to bolt on. Custom ECU calibration is required. All Ford Racing ETC throttle bodies feature: • All factory sensors installed — no need to try and take apart your original throttle bodies • Calibrated for idle airflow using the same procedure as production throttle bodies • Precision billet construction with tapered inlet for consistent high flow • Polished aluminum for great looks • The only throttle bodies backed by Ford Racing with the logo CNC’d in • Validation through hundreds of hours of dyno, racing and street performance driving PART NUMBER ENGINE FITS SIZE REQUIRES NOTES M-9926-M5090 5.0L DOHC Coyote 2011-2013 Mustang GT/ 90 mm Adaptor M-9474-M50 Adaptor M-9474-M50 rotates 2012-2013 BOSS 302 for OEM Mustang GT throttle body approximately (stock 80 mm) 5.0L 4V Ti-VCT intake 15% counterclockwise Adaptor M-9474-M50B Engine cover M-9680-M50 for Ford Racing BOSS covers throttle body on intake M-9424-M50BR 5.0L 4V Ti-VCT intake Requires use of a 4" ID When using factory 3.5" diameter air silicone hose adaptor inlet tube, the molded rubber throttle or reducer, sold body hose must be removed separately. 4" air inlet tube is recommended for Includes jumper harness maximum horsepower Calibration required BOSS intake M-9424-M50BR can be port matched to accept throttle body w/out adaptor, requires custom gasket/RTV M-9474-M50B BOSS 302 2011-2013 Mustang GT/ 90 mm Adaptor for M-9474-M50BR Spacer used to adapt 90 mm Billet 2012-2013 BOSS 302 Throttle Body Aluminum Throttle Body, M-9926-M5090, to 2012 BOSS 302 M-9424-M50BR intake Intake M-9424-M50BR and M-9926-M5090 Throttle Body M-9474-M50 5.0L 4V Ti-VCT 2011-2013 Mustang GT 90 mm M-9926-M5090 Spacer rotates throttle body Throttle Body and approximately 15% counterclockwise OEM 5.0L intake to clear intake cover M-9926-M50845 5.0L 2011-2013 Mustang GT/ 84.5 mm Requires use of 4" ID When using factory 3.5" diameter 2012-2013 BOSS 302 silicone hose adapter or air inlet tube, the molded rubber (stock 80 mm) reducer, sold separately. throttle body hose must be removed 4" inlet rube is recommended for maximum horsepower.
