Great plugs and great price!
OEM parts always make the job easy and right the first time. These plugs made an instant difference in the fuel mileage and were a great price. Saved $40 buying them through Walmart vice the auto parts stores for the exact part we needed.

OEM replacement at a good price.
Perfect fit for my 2011 Sonata SE. Replaced the original DENSO plugs after 125k of reliable service. Idle is smooth and acceleration is strong. Right plugs at a good price.
