Genuine OEM 18875-08085 Spark Plug 4 PCs Set / 1887508085 for Hyundai Sonata 2020-2021 Kia K5 2021 1.6L L4

Bought these for my 2021 kia k5 gt-line 1.6 literally and they were gapped perfect already. Dealership wanted over 300 to change my plugs. I bought these and did it myself in about 30 to 45 minutes and saved over 200 bucks. Engine runs smoothly, just like when it was new. Very easy to install and the quality and perfect fit made doing it myself so easy.

No issues here. Put on my car that has 100k miles on it.

Purchased for a 2021 Kia K5 GT

Spark plugs are the correct type for my 2023 Hyundai Tucson Hybrid, even though the model description does not list it. The part number is consistent with Hyundai info. When they arrived, I confirmed the part number match. All good.

These are the same sparkplugs that are on my Hyundai vehicle. Yes they are iridium plugs and should last 100k miles but I like to change them much sooner as this does not cost a lot of money and can help car last longer. I change them every 4 years. No errors codes and no misfire reported. Great sparkplugs...

2021 Kia K5 LXS.Went in perfect and was already pre-gapped.

Bought a set of 18875 08085 spark plugs for my 2021 Kia Sorento hybrid before the price went up.I don't need to use them yet, but my owners manual says to replace them at 42,000 miles.(Seems too soon as most plugs these days are good for 100,000 miles.)Just to be safe, I bought them as I now have 29,000 miles.Unboxed the four plugs and they appear to be well made.Checked the gaps - three allow .25 wire through but not .30.Owners manual does not state exact gap, but I suspect it to be .28.HOWEVER, one would not allow .25 to pass through and had to be adjusted.NOTE: Irridium is very brittle. When making gap adjustments be very carefulthat NO pressure is applied either to the irridium electrode or to the ceramic insulation.Both can be easily damaged ruining the expensive part.Requiring gap adjustment is why I awarded 4 stars.Keep in mind that I have not installed the plugs.UPDATE: On 02/17/2024 I replaced the original plugs with these at 40,665 miles.The original plugs looked good with a small buildup on the bottom of the side electrode.I sanded the originals, checked the gaps (which needed minimal tightening) and put them inthe just-emptied boxes. In 40,000 miles or so, I'll swap the plugs again. Looks to me like the two setsof plugs have me covered for 200,000 miles. Usually I follow the owner's manual, but they mustbe allowing for harder vehicle use than mine experiences. (Broken is as recommended, driven gently, rarely exceed 65 mph - while returning 38 mpg.)

This is a set of 4 Spark Plug , Greta quality , this pieces are for my car ,good quality , easy to install.
