Hello, I received my order today, but all 4 spark plugs are missing. Only the empty boxes of the spark plugs arrived in the package. This is a serious issue. Please send the missing items immediately or issue a full refund without delay. Thank you for your prompt response.

How the star rating is calculated

Customer reviews and star ratings help our customers learn more about a product and decide whether it is worth buying. A complex algorithm is used to calculate the star rating, taking into consideration how long ago the review was made, whether the item was actually purchased in the AUTODOC online shop, and whether it was returned or not.

How we verify reviews

The tag "verified purchase" allows you to find reviews from customers who have actually purchased the item in question from the AUTODOC online shop. The "verified purchase" label applies to reviews of items purchased from the same account the reviews were submitted from. We still consider reviews without the "verified purchase" tag to be important, but we can't guarantee that the items described in such reviews were purchased in the AUTODOC online shop.
