Great price
Great price for Champion spark plugs. Arrived each in their small factory packaging (small boxes) inside a padded pouch. They work great.

Quality product
Good quality. Gap was not accurate but you can fix that with a rock if you are extra cheap.

Works as expected
Bought these ( one as a spare) to replace an old crusty one in my RV generator. After adjusting the gap, the gen fired right up.
