OEM Supercharger Gauge Pod For Mustang GT

The gauge pod is designed as original equipment on 2015-2017 Performance Pack 2.3L EcoBoost Mustangs and fits 2015-2021 Mustang GTs with Performance Pack dash gauges. It features oil pressure and vacuum/boost gauge integration, enabling drivers to monitor critical metrics during high-load driving and tuning sessions. The pod’s construction supports clean installation and reliable display alignment, which is important for ongoing track and street performance monitoring.
Ford Racing Boost Gauge Kit

This boost gauge kit is aligned with the 2015-2017 Performance Pack and is suitable for 2015-2020 Mustang GT models. It provides a dedicated boost gauge along with dash integration that mirrors factory instrumentation. Reading boost in real time helps drivers gauge turbocharger response, intake pressure, and tuning progress, supporting precise adjustments for performance gains and engine safety during boosted operation.
BBK Underdrive Pulley Kit

The BBK Underdrive Pulley Kit reduces parasitic drag by decreasing accessory drive loads. Crafted from lightweight CNC-machined aluminum, the kit is designed for Ford Mustang 4.6/GT engines and contributes to improved throttle response and potential gains in engine efficiency. This upgrade is a popular choice for enthusiasts seeking simple bolt-on enhancements that complement a boosted setup or performance-focused tune.
J&L Oil Separator 3.0

Engineered for modern EcoBoost and gas-powered engines, this oil separator features detailed install directions, a plug-and-play design, and serviceability. It helps manage crankcase ventilation by separating oil from crankcase gasses, which can improve intake cleanliness and aid in maintaining consistent boost levels during spirited driving and boosting scenarios on the Mustang GT platform.
ICT Billet Engine to Transmission Bolt Kit

This bolt kit uses metric flange bolts with heavy-duty, high-strength properties and zinc coating for corrosion resistance. It’s designed to secure critical engine-to-transmission connections, which is essential for maintaining reliability in boosted or high-performance configurations where accurate mating surfaces and torque retention matter for long-term durability.
Buying Guide
- Compatibility: Verify model years (2015-2021) and your Mustang GT’s trim (Performance Pack presence can affect gauge and gauge pod compatibility).
- Purpose: Distinguish between monitoring (boost, oil pressure, vacuum) and performance enhancements (pulleys, bolting kits, oil management). Choose a mix that aligns with your goals, whether tracking, daily driving, or street tuning.
- Installation: Consider the complexity and required tools. Some items are plug-and-play, while others may need professional installation to ensure proper fitment and sealing.
- Durability: Look for CNC-machined components and corrosion-resistant finishes for long-term performance under high-boost conditions.
- Maintenance: Items like oil separators require periodic checks and possible servicing to sustain performance benefits.
- Cost vs. Benefit: Weigh perceived gains in horsepower, throttle response, and reliability against the price and potential installation costs.
- Tuning Compatibility: Ensure gauges and sensors align with your ECU and any aftermarket tune you plan to run to avoid skewed readings or sensor conflicts.
- Warranty and Support: Prefer brands offering installation guidance and reputable customer support in case of compatibility questions.
When building a high-performance Mustang GT, a balanced approach that combines monitoring—via a reliable gauge pod and boost gauge—with strategic supporting hardware—like a lightweight pulley kit, oil separators, and robust fasteners—often yields the best overall results. Always verify compatibility with your specific configuration and consult professional installation if you’re upgrading critical engine components or boosting infrastructure.
