V6 Spark Plug Holder V2.0

thingiverse

Spark plug holder made by me, designed to securely hold my plugs after they've been gapped and replaced, with the firing sequence for a Buick Turbo V6 engine. The holder allows you to gap your plugs and then protect them, and when removing an old plug, flip it upside down so you can examine its condition. There's a small notch at the bottom of each hole where you can grab the terminal and keep it in place. The holder is carefully crafted to fit snugly around AC Delco R42TS plugs. Feel free to modify! - I've added a version without the firing sequence. - I've also added a version with neither firing sequence nor direction.
