Ecotec Extended Injector Cups (Set of 4) – Precision Spacers for Custom Fuel Rail & Injector Swaps

Upgrade your Ecotec fuel system reliability with the BK Racing Extended Aluminum Fuel Injector Cups (Set of 4) — the best extended aluminum injector cups for GM Ecotec NA models, precision-crafted from high-grade billet aluminum for superior strength, rapid heat dissipation, and extended service life over fragile OEM plastic cups. These +4mm extended cups are essential for seamless swaps using shorter high-flow injectors (e.g., Cobalt SS injectors into L61 heads) while maintaining optimal spray patterns and secure sealing.

Stock plastic cups trap heat, leading to brittleness, O-ring degradation, warping, and potential leaks — especially in high-compression or boosted setups. BK Racing's billet aluminum design excels with faster cooling (per Newton's Law of Cooling), dropping injector temperatures significantly in real-world testing and simulations, extending component life 2-3x in 3-4 bar systems, and preventing common failures like rough idling or fuel starvation.

Key Technical Advantages Over Stock Plastic:

• Rapid Heat Dissipation: Aluminum conducts heat away quickly, protecting injectors and O-rings from thermal damage
• +4mm Extended Design: Perfect for shorter injectors in custom rails or head swaps — preserves ideal fuel atomization and port targeting
• Unmatched Durability: High melting point and robust billet construction resist warping, cracking, and stress in daily driving or light track use
• Superior Sealing: Compatible with high-quality O-rings for leak-free performance under pressure
• Precision Engineering: CNC-machined for exact fit, secure injector retention, and enhanced overall fuel delivery efficiency

Performance Benefits:

• Cleaner combustion, smoother idle, and consistent power in modified NA or mild boosted Ecotecs
• Reduces risk of heat-soak related misfires or injector failure
• Ideal for high-flow injector upgrades, custom fuel rails, or head/porting projects
• Essential companion to BK Racing rebuilt DEKA injectors and valvetrain components

Compatibility:

• GM Ecotec naturally aspirated/port-injected engines:
  • 2.2L L61 (Chevrolet Cavalier, Cobalt base, HHR; Saturn Ion, Vue; Pontiac Sunfire, G5)
  • 2.4L LE5 (Chevrolet Cobalt/HHR/Malibu; Pontiac G5/G6/Solstice; Saturn Ion/Sky/Aura)
• Perfect for injector swaps requiring additional length (e.g., LSJ/LNF injectors into L61 heads)

Installation Note: Simple drop-in with standard tools — lubricate O-rings and ensure proper clip engagement. Off-road and performance use recommended.
