EMS – Ultimate Aux Fuel Solution (UAFS) Bundle for 2013-2018 Focus ST or RS

Boost Your Focus ST or RS with the EMS 1300CC Port Injection Bundle

Looking to get more power and better fuel efficiency out of your 2013-2018 Ford Focus ST or RS? Our EMS 1300CC Port Injection Bundle is designed to enhance your engine’s performance while keeping it running clean and strong.

What is Port Injection, and Why Does It Help?

Your Focus ST or RS comes with direct fuel injection, which is great for efficiency but can cause carbon buildup on the intake valves over time. Port injection adds an extra layer of fuel delivery before the combustion process, leading to better fuel mixing, more power, and cleaner engine operation—especially when using E85 fuel.

What’s Included?

This kit provides everything you need for an easy upgrade:

• UAFS with Optional Wiring Integration – Ensures precise fuel delivery (You have to send in your harness or schedule your appointment for in house installation)
• Maxx ECU MINI – Manages the port injection system for optimized performance
• FlexFuel Sensor – Adjusts fuel delivery when running E85 or pump gas
• Spacer – Helps install injectors correctly
• 1300cc Injectors – High-flow fuel injectors for increased power

Why Upgrade?

• More horsepower and torque – Unlocks the full potential of your Focus ST or RS
• Improved fuel control – Works seamlessly with E85 for maximum performance
• Reduced carbon buildup – Helps keep intake valves clean for long-term reliability
