BLOX Racing XTREME 90mm DBW Throttle Body – 2015–2017 Ford Mustang GT 5.0 / F-150 5.0L | Coyote Gen 2 | BXIM-00295-SI

BLOX Racing BXIM-00295-SI XTREME 90mm drive-by-wire throttle body for the 2015–2017 Ford Mustang GT 5.0L and Ford F-150 5.0L — both using the Gen 2 Coyote V8. CNC machined from billet aluminium with a 90mm bore — a 10mm increase over the OEM 80mm unit, providing approximately 26% greater maximum airflow cross-section. Includes OEM-compatible DBW motor and TPS connector for direct plug-in installation. 2 lbs. Ships fast across Canada and the US.

90mm vs OEM 80mm — What the Bore Increase Does

The Gen 2 Coyote’s OEM throttle body is 80mm. The BLOX XTREME increases this to 90mm:

• Airflow cross-section: Throttle body flow area scales with the square of the bore diameter. 90mm vs 80mm = 90²/80² = a 26.6% increase in maximum flow area at wide-open throttle. This does not translate to a 26% power increase — the throttle body is not the primary restriction on a stock or mildly modified naturally aspirated Coyote. The gain is most pronounced when the intake airflow is a genuine bottleneck.
• Naturally aspirated builds: On a stock or lightly modified naturally aspirated Mustang GT or F-150 5.0, the throttle body upgrade alone produces modest measurable gains (typically 5–15 whp on a properly tuned car). The primary benefit is improved high-RPM airflow and a more linear wide-open-throttle response as the engine no longer approaches the OEM throttle body’s flow ceiling.
• Forced induction and high-lift cam builds: On a supercharged (Roush, Whipple, Edelbrock E-Force) or turbocharged Coyote, or on a high-lift camshaft build with ported intake manifold, the throttle body becomes a more significant restriction. A 90mm unit on a boosted Coyote contributes meaningfully to overall airflow capacity and complements the rest of the induction system upgrade.
• Throttle response: The larger bore changes the throttle blade’s effective area at partial openings, which can make tip-in feel more responsive — a smaller blade movement produces more airflow change. This is a subjective improvement in throttle feel for many drivers, though it requires adaptation from stock feel. A tune optimises the electronic throttle mapping to match the new bore.

Drive-By-Wire (DBW) — Plug-and-Play Integration

The 2015–2017 Coyote uses electronic throttle control — no mechanical cable connects the accelerator pedal to the throttle plate. The BXIM-00295-SI includes the complete DBW assembly:

• Integrated DBW motor: The throttle plate actuator motor is built into the throttle body housing — no separate motor sourcing required.
• TPS (Throttle Position Sensor): Throttle position sensor is integrated and uses the OEM connector — plugs directly into the factory wiring harness without modification.
• Plug-and-play installation: Disconnect the OEM throttle body’s electrical connector and coolant hoses (the OEM throttle body has a coolant passage to prevent throttle plate icing), remove the OEM unit from the intake manifold, install the BLOX unit, and reconnect. No wiring modification required.
• Coolant bypass: The BLOX unit may not include the OEM’s coolant heating passage. A coolant bypass fitting may be required to cap the coolant lines. Confirm with the included installation instructions.

Coyote Generation Compatibility — Critical Fitment Note

The Ford 5.0L Coyote V8 was produced in three generations with different throttle body specifications:

• Gen 1 (2011–2014): Mustang GT 5.0 and F-150 5.0. Uses a different throttle body flange and DBW connector. Not compatible with BXIM-00295-SI.
• Gen 2 (2015–2017): Mustang GT 5.0 and F-150 5.0. This is the correct application for BXIM-00295-SI. Both Mustang S550 and F-150 of this generation share the same throttle body mounting and DBW system.
• Gen 3 (2018+): Mustang GT 5.0 (and later variants). Revised engine architecture with a different throttle body specification. Not compatible with BXIM-00295-SI — a different BLOX or aftermarket unit is required for Gen 3 applications.

Mustang GT and F-150 5.0 — Both Applications

The Gen 2 Coyote’s shared architecture means one throttle body covers both platforms:

• 2015–2017 Ford Mustang GT (S550): The primary performance application. Common pairings include cold air intake, mid-pipe, axle-back, and tune for a complete naturally aspirated bolt-on build. Supercharger builds (Whipple 2.9L, Edelbrock E-Force) benefit significantly from the 90mm TB upgrade as part of a supporting mod package.
• 2015–2017 Ford F-150 5.0L: The performance truck application. F-150 5.0 builds share many of the same components as the Mustang GT — the shared Coyote architecture means intake, throttle body, and induction upgrades designed for the Mustang often apply directly. Popular in drag truck and street truck builds.

2015–2017 Coyote Gen 2 only — Mustang GT 5.0 and F-150 5.0L. Not for Gen 1 (2011–2014) or Gen 3 (2018+). DBW — plug-and-play. 90mm billet bore. Tune recommended. Check coolant bypass requirement.
