About Us

Since 2013, ASSOSARY has been the trusted partner of professional mechanics, performance tuners, and discerning DIYers who demand uncompromising quality in fuel injection systems. Born in California's automotive heartland and manufactured in our state-of-the-art Fo shan facility, we've shipped over 2 million precision fuel injectors to satisfy America's toughest engine builders. Now, we're bringing our decade of injection expertise to Ireland's vibrant automotive community.

Engineering Excellence: The ASSOSARY Difference
1. American Performance, Chinese Precision
Our journey began supplying high-performance shops along Route 66, where we learned what injectors truly need to survive. Today, our ISO/TS 16949-certified factory in China's automotive capital combines:
Robotic calibration benches with 0.1μm accuracy
Military-grade cleaning protocols (each nozzle ultrasonically cleaned)
100% cold-flow testing under simulated Irish weather conditions (-10°C to 40°C)
2. Next-Generation Injection Technology
The secret to our injectors' 30% longer service life lies in:
✓ 8-Hole Nano-Coated Nozzles (versus standard 4-hole designs)
✓ Dynamic Flow Matching (±1% variance across matched sets)
✓ E85 Biofuel Compatibility (with free ECU tuning guidelines)
3. Proven in Competition, Trusted Daily
From Baja 1000 race trucks to New York taxi fleets, our injectors deliver:
15% better atomization (verified by SAE J2715 testing)
Self-cleaning piezoelectric design (prevents Irish damp-weather clogging)
Direct replacement for Bosch/Denfi systems (no ECU reprogramming needed)
