Upgrade from OEM
After seeing a quite ludicrous $403 quote to change 4 spark plugs in a Mazda3 I decided to show my son how easy it is. These were an upgrade from OEM parts. They were gapped perfectly for the car. They took 20mins to fit and work fine.

garbage spark plugs
misfired after 30 minutes of driving cylinder 4 misfire code, left me stranded on the highway with baby in car. “(9621)” at the end of description is a lie, was not compatible with my vehicle even with compatibility test.

Actually works on BMW!
I purchased this after the shorter black fluted tool I bought last year failed me. This thing is way better constructed, fits perfect , and actually works to turn it after you can’t turn it by hand any further. Was able to get torqued down to 25nm no problem finally with ease!
