1. Top-Feed Injectors

The most common design — fuel enters from the top. These are easy to install and service, making them a favorite for both OEM and aftermarket setups.

• Simple and cost-effective
• Easy to replace or upgrade
• Widely used in performance vehicles

2. Side-Feed Injectors

Fuel enters from the side, making them ideal for compact engine bays.

• Space-saving design
• Great for engines with limited room
• Slightly more complex fuel rail setup

3. Port Fuel Injectors (PFI)

PFIs spray fuel into the intake manifold just before the intake valve — ensuring a clean, efficient mix.

• Reliable and easy to maintain
• Great balance of power and efficiency
• Found in most modern gasoline engines

4. Direct Fuel Injectors (GDI / DFI)

These injectors deliver fuel directly into the combustion chamber for precise fuel control and higher performance.

• Boosts power and efficiency
• Reduces emissions
• Needs regular cleaning to prevent carbon buildu
