Key Specifications

Lifetime Warranty

Durability is just as important as performance. Excess 1000cc fuel injectors feature stainless steel internals, making them compatible with all types of fuel while resisting corrosion and wear.

And the best part? Every set comes with a Lifetime Warranty. If an injector fails due to a manufacturer defect (not contamination or damage), Excess will replace it—no hassle, no questions asked.

• All-fuel compatible
• Guaranteed flow and deadtime matching
• Cloud-stored injector data for easy future reference

When upgrading to larger injectors, accuracy matters. Excess Injectors are flow-matched, deadtime-matched, and come with custom tuning data, ensuring seamless integration with your engine's ECU. Here's why these injectors are a top-tier choice.

Exact Match Data for Easy Tuning

Every set of Excess Injectors comes with Exact Match Data, meaning your injectors are tested and tuned specifically for your set. Unlike generic tuning files, Excess provides customized tune files for 11 different ECUs, reducing dyno time and making tuning hassle-free.

• Each tune file is adjusted to match your set's real-world performance
• No two data sets are the same
• Pre-configured for multiple ECU/software types

Testing Precision

Excess Injectors are tested under strict J1832 standards, ensuring that every injector meets exacting performance criteria.

• Pressure is electronically controlled at 3 bar
• Temperature is stabilized at 21°C
• Voltage is precisely set to 14V

By maintaining these tightly controlled conditions, Excess achieves consistent, reliable results, so you know exactly how your injectors will perform.

Tightest Flow & Deadtime Matching

Unlike many aftermarket injectors that only offer basic flow testing, Excess Injectors are dynamically flow-matched within 1% and deadtime-matched within 2%.

• Over 6,500 flow points tested per injector
• More than 265,000 measurements were recorded for each injector

With this level of precision, your engine gets a perfectly balanced fuel delivery, leading to smoother performance and optimized tuning.
