Good 1st up grade for the New Age WRX wanting to go to the next level. These top feed injectors flow circa 505cc at the standard 3bar fuel pressure, and this can be increased to circa 550cc if an adjustable fuel pressure regulator is fitted, and the pressure is raised to 3.5bar.

These are carefully selected used STi Pink or Blue injectors that have been ultrasonically cleaned, new o rings, and flow matched.
