Good convenient Because it has 2 dimensions. In my car it didn't fit Because it didn't go in all the way so I took a spark plug key and used it as an extension to remove the spark plug.

It's not very convenient. The only good thing is that with these pliers you can solve almost all the problems.

I bought this specific key for changing car spark plugs and although it is of good quality, it is not at all convenient for changing car spark plugs. I do not recommend it for purchase. It does have three small nuts for spark plugs that might come in handy somewhere, but the overall experience is not pleasant

It helps with changing spark plugs, especially for Scooters where access is difficult. It has 2 bolts, one 16mm & 19mm. It fits perfectly with spark plugs for Piaggio Beverly 350 scooters.
