Grams Performance Nissan/Infiniti 350Z/VQ35/G35 1150cc Fuel Injectors (Set of 6)

If you're looking to get more out of your 2003-2009 Nissan 350Z or 2003-2007 Infiniti G35, these 1150cc fuel injectors from Grams Performance are a solid choice. They play a critical role in how your engine runs by accurately spraying fuel into the cylinders. When you're pushing your engine harder, especially with modifications, the stock injectors might not be able to keep up, leading to lean conditions or inconsistent fuel delivery. These injectors are designed to handle higher fuel demands while ensuring each cylinder gets the right amount of fuel.

What sets these injectors apart is their construction and testing. They feature stainless steel internals, which means they can handle a wide variety of fuels, including oxygenated ones like FTW, Q16, and M5, without issue. Grams Performance individually balances and flow-tests each injector, matching them within 1% of each other. This attention to detail means you get unmatched cylinder-to-cylinder consistency, which translates to a smoother idle, better throttle response, and more reliable performance, even when the engine is only using a little bit of fuel at low speeds. The solenoids are also very fast and precise, allowing for accurate fuel metering even at very high fuel pressures and short injection times.

This set includes six injectors, a black bottom adapter, and EV1 pigtails. You will need to splice the wiring to connect them. Keep in mind these are not CARB approved and cannot be shipped to California. They are a high-impedance design, which is important to note for your ECU tuning.
