2022/9 NOTE: I will be making edits to all the different Spark Plugs that have been noted in owners manual to this page and then will apply the changes to the other pages in the near future. If you have an Owner's manual that is not referenced below, please take a photo of the (a) cover, (b) then of the inside page that dates the owner's manual, (c) the page that lists the spark plugs. Please send this info to my email and let me know if you want me to credit you on the website. Thank you!

Note: See the relevant service manual or driver's manual for your car to determine which one is correct.
