The Grams Performance 1600cc injector kit for Miata NA/NB 1.6/1.8 engines provides a set of four high-impedance injectors with stainless internals and fast, linear-response solenoids to improve metering accuracy across conditions. Each injector is individually flow tested and dynamically matched for 1% consistency to preserve idle quality and cylinder balance.
