dont waste your money on those expensive plugs, NGK plugs are recommended Kia had some issues with Champion plugs and recommend NGK'S

ngk plugs make a good plug and are not expensive.

Definitely stay away from the Bosch and Autolites as I've seen them cause misfires in Kia. Champion or NGK are OEM plugs on most Kia vehicles I've seen. I agree with everyone else that if it was my vehicle I'd go with the NGKs.


OEM would be the best, autolite or bosch is fine. NGK are crap.


KIA + OEM = NGK so don't be gay! OK

I have a 2006 Kia Sorento LX 3.5 with 94567 miles. I am installing NGK Iridium ix BKR5EIX-11 stock no. 5464. I took out the OEM factory plugs that were Champion RC10PYPB4 Double platinum. The Champion were fantastic plugs and the car had zero issues with them. I am installing the Iridiums so i will go another 100k miles in between changes and they were readily available at the local parts store.. The spark plugs are a bear to install. I suggest to anyone doing the job to go ahead and install new valve cover gaskets at the same time.You will need to be very patient as this is a time consuming and tedious job.

Just saw in the past that somebody said ngk are crap...for any future browsers research them. Used in many high performance cars and motorcycles because of their reliability. Its all I've ever used in a 305, 350 tpi, 400, 5.7 hemi, 5.4 ford, 5.7 ls1, 6.2 ls3, gsxr750, and gsxr1000. Never had 1 problem with a plug.
