2001 Kia Optima V6 2.5L 6 Piece Fuel Injector Set TRQ FIA60444

My neice has a 2006 hyundai Santa Fe, it started having a rough idle and eventually started stalling. Put a code reader and it said misfire in cylinder 5, had her take it to a shop since I did not want to pull the top off the engine and they said it was a faulty spark plug, 700$ to repair. Not about to pay that so I brought it home and tore the top off, took out the spark plug and it was cracked on the ceramic. Replace it-1 week later same issue, same plug. So looking into, turns out that a bad fuel injector can cause too much air-too much bang and will crack spark plug insulators. Well wouldn't you know it that a single injector is about 50-80$ in store and this whole set was a lot cheaper by comparison. These fit right in, no issues- and it fixed the issue the car was having too. Saved a good amount of money doing this myself.
