Spark plug NGK 3961 : Review and evaluation
Have you ever bought this product from AUTODOC: NGK Spark plug 3961?
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.
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.

W.K.: Good morning,
Please confirm the NGK 3961 BR8ES has a solid top, not removable.
I have allways used these solid top spark plugs in my Rotax 447 air cooled and 582 Blue Top premixed fuel 2 stroke engine in my microlight aircraft.
