Good but necessary threading

Good product, works as expected after I cleaned the threads with a tap and removed the serrated drill bit before the spark plugs were received smoothly.

Pros
  • Made from high quality CNC aluminum strong and strong enough to last longer
Cons
  • Slightly different

Miscut 14mm thread

Bought the 14mm threaded version. A plug with a 14 mm thread (NGK B8EG) only partially fits. The connector is partially threaded. Had to one tap chase the streams for it to work.

Pros
  • 100% brand new Cosmoska spark plug spacer tool
Cons
  • poorly thought out

Generally good - spark plugs

Good product - nice aluminum body and large knurled knob - wish the screw was steel instead of aluminum or at least 1-2 larger in diameter. A better design would be a shoe that would flatten the tip of the fork instead of flexing it. Now he's bending the tip forward and the faces aren't quite parallel. The shoe causes the tip to be parallel to the tip of the electrode, creating a larger contact area between the spark and the flame. But of course nobody will build such good devices because they…

Pros
  • Universal fits all 12mm thread spark plugs
Cons
  • Compatibility
