DeatschWerks Mazda Miata (NA/NB) 650cc Injectors - Set of 4

These DeatschWerks 650cc fuel injectors are built with a stainless steel internal component and a robust plastic body, making them a well-built option for your 1990-2005 Mazda Miata. When you're looking to increase horsepower or make other engine modifications, upgrading your fuel injectors is a critical step. Stock injectors often can't supply enough fuel to meet the demands of a performance-tuned engine, leading to lean conditions that can damage your motor. These injectors flow 650cc per minute, giving you the headroom needed for significant power gains.

DeatschWerks is known for their flow matching process, ensuring that each injector in the set flows within a tight tolerance of the others. This consistency is important for smooth engine operation and predictable fuel delivery. The injectors are designed as a direct fit for the Miata chassis, meaning installation should be straightforward, replacing your factory units without requiring extensive modifications. They are a popular choice for Miata owners who are building more powerful engines, whether for track use or spirited street driving.

It's important to note that these injectors are not CARB approved and cannot be shipped to California. You will also need to have your engine's fuel management system tuned to take full advantage of the increased flow rate and ensure optimal performance and engine health.
