600cc - هيونداي جينيسيس كوبيه 3.8 2009-2012

These fired right up on the first try after I installed the set, no leaks and the idle is smoother than it was with the stock parts. The fact that they're a matched set of six for a direct fit saved me a ton of hassle with tuning.

Swapped these in over the weekend on my 2010 3.8 and the direct-fit design saved me from any wiring or adapter headaches. Idle smoothed out immediately and the car's been pulling hard without a single hiccup since.

Installed these on my 2009 3.8 and the direct-fit design meant zero modification needed, just swapped the six injectors in about an hour. Fuel trims settled right back to normal and the car pulls noticeably smoother at higher RPMs.
