550cc - Ford Focus MK2 ST/RS

Dropped these into my MK2 ST and they fit perfectly, car idles smoother than with the old clogged ones. The 550cc flow seems spot-on for my tune.

Five injectors in the box, all with the same 550cc rating, so it was a straightforward swap on my MK2 ST. The car idles clean and pulls hard without a hiccup, and the kit being a complete set saved me from hunting down a missing one. Worth every penny for the peace of mind alone.

I noticed a solid improvement in throttle response right after swapping to these 550cc injectors. The five-piece set made for a clean, complete replacement without any guesswork.
