Actually, I purchased 8 Denso plugs because at the time I couldn't find the NGK plugs at a reasonable price.

To me, DLE is not in the sparkplug business and don't need to furnish one at all. But its nice they do so perhaps you can see that the engine runs. Like SuperTiger glow plugs, usually good for one run and then discard.

Modelers need to seek liability for their own actions and the use of any products from themselves. Not the manufacturers. Otherwise there wouldn't be a "DLE" type alternative to us.
