Description

The STI 16611-AA370 is a set of four refurbished and flow-matched Denso 565cc fuel injectors. These are original equipment Denso injectors, not reproductions. They feature high impedance and have been tested using state-of-the-art ASNU equipment, specifically upgraded for high-flow, high-performance injectors. These injectors are a common upgrade for EJ20 engines paired with a VF or 16G turbocharger. They have a proven track record of supporting up to the 300 wheel horsepower mark. Each set comes with a flow sheet detailing the injector's performance data and is backed by a 6-month warranty. While these are listed with part number 16611-AA370, they are also interchangeable with part numbers 16611-AA510 and 195500-3910. The physical appearance, including filters and pintle caps, may vary from the stock photo.
