550cc - Kia Forte

Plugged these into my 2013 Forte and the idle smoothed out immediately—the precise fuel flow is noticeable. Fits perfectly with no leaks, and the car feels more responsive under acceleration.

Had a bit of a rough idle before swapping these in, and now the engine runs smoother than it has in years. The matched set made installation straightforward, and the flow rate feels spot on for my daily driving needs.

The matched set fired right up in my 2012 Forte with zero sputtering—idle is smoother than it's been in months. Fuel delivery feels precise, and the four injectors were spot-on the same flow right out of the box.
