Fuel rail says mpi.I don't know what type.
You can go to your nearest kia/Hyundai dealership & ask at the parts counter & buy from them.
Have a ride at the ready & you can remove one of yours.
Go to your local Autozone, O'Reilly's, advanced auto parts, Pepboys & Napa.
If 2010 thru 2013 kia Fortes use iridium NGK & Denso. I'm sure 2014 thru 2021 use iridium spark plugs. Dont fall for those fancy ones. Save yourself any engine problems & stick with NGK & Denso iridium spark plugs.
Same with engine oil filter & transmission filter (if it's an Automatic) stay with OEM/factory.
Hope this helps.
Also post/upload pics. Helps out the Forte community.
