Electronic Fuel Injection Throttle Kits

Porsche Electronic Fuel Injection Throttle Kits - Precision Airflow & Throttle Control

Electronic Fuel Injection (EFI) Throttle Kits upgrade the engine’s air delivery system, providing precise throttle control, improved airflow, and enhanced engine response. Designed for performance builds, engine conversions, and modernised classic Porsche applications, these kits replace restrictive or outdated throttle systems with advanced electronic throttle bodies and control hardware.

Available from Design911, Porsche EFI throttle kits are engineered to deliver smoother power delivery, sharper throttle response, and improved drivability—especially in tuned, high-performance, or track-focused engines.

What Do Electronic Fuel Injection Throttle Kits Do?

EFI throttle kits regulate the volume of air entering the engine with high precision, directly influencing power and response.

Core Functions:

• Control engine airflow electronically and accurately.
• Improve throttle response and drivability.
• Support higher airflow demands in tuned engines.
• Enable precise fuel and ignition mapping.
• Enhance overall engine efficiency and performance.

Accurate throttle control is essential for modern performance engine management.

Why Do Standard Throttle Systems Fail?

Factory or older throttle systems can become limiting or unreliable over time, particularly in modified engines. Common issues include:

• Mechanical throttle wear or cable stretch.
• Inconsistent airflow from ageing throttle bodies.
• Restrictive designs limiting high-RPM performance.
• Poor compatibility with modern ECU tuning.
• Inadequate response for high-performance applications.

These limitations can result in sluggish response, uneven power delivery, and reduced tuning potential.

Why Upgrade to an EFI Throttle Kit?

EFI throttle kits are designed to support modern engine management and higher performance demands.

Upgrade Benefits:

• Sharper, more consistent throttle response.
• Increased airflow capacity for power upgrades.
• Improved compatibility with aftermarket ECUs.
• Enhanced drivability for road and track use.
• Ideal for engine builds, conversions, and restorations.

Upgrading to an EFI throttle kit unlocks precise control and maximises engine tuning potential.
