Why S&S?

S&S Diesel Motorsport uses advanced testing and precision manufacturing that regularly outperforms other injectors of the same claimed size. Every set is thoroughly validated for consistent delivery and reliable operation.

Important Notes

• Core return is required
• Custom tuning is strongly recommended to properly manage fueling, smoke, and drivability with the increased flow. Supporting modifications (fuel supply, filtration, exhaust, etc.) are advised for higher power goals.
• Pair with a quality injector line kit and fresh fuel filters.

These injectors are engineered for serious performance builds while retaining the durability and tight matching that define S&S products.
