Great Plugs
Great spark plugs at the fraction of the price compared to the car dealers or anywhere else for that matter. This was my first purchase from Denso, but definitely not the last.

What can I say other than a Denso product? Great price from CARiD, great customer service. These are the spark plugs for my wife's Honda. Replacing originals after 110K miles. Thank you CARiD!
