Hyundai Sonata 2013 Peace be upon you. Folks, I have a set of spark plugs for a 2013 Sonata. The spark plugs need cleaning only, and they are in good condition, no complaints. The reason for changing them is that I bought a set of sports spark plugs and installed them. The original spark plugs are fine. Selling to the highest bidder. Please contact the number provided in the designated field.
