Grams Performance 1150cc E90/E92/E93 INJECTOR KIT

If you're looking to significantly upgrade the fuel system on your 2008-2013 BMW M3, this set of eight 1150cc fuel injectors from Grams Performance is a solid choice. These injectors are crucial for delivering the right amount of fuel to your engine, especially when you're pushing its performance limits. Accurate fuel delivery and atomization are key to getting the most power and efficiency out of your engine, and these injectors are built to handle that job.

Grams Performance builds these injectors with stainless steel internals, making them compatible with a wide range of fuels, including oxygenated options and specialized performance fuels. Each injector in the set is individually balanced and then flow-tested and dynamically matched to within one percent of each other. This ensures that every cylinder receives a consistent amount of fuel, even at very low pulse widths, which helps maintain smooth idle quality and improves overall engine response and performance. The solenoids are designed for ultra-fast and precise operation, allowing them to accurately meter fuel across a broad spectrum of operating conditions, even at high fuel pressures and short pulse widths.

This kit includes black bottom adapters and EV1 pigtails, but you will need to splice wires for installation. Because these are high-performance injectors, they are not CARB approved and cannot be shipped to California. Make sure to check the manufacturer's installation instructions for details on wiring and proper setup.
