Steve's Miniature Sparkplugs

Home of the worlds smallest production sparkplug

Steve's Miniature Sparkplugs is a very small business dedicated to building quality sparkplugs for the model engineering community. All our plugs are hand made in small batches. Every sparkplug is made using steel bases, Corian for the insulator, and brass for the cap. These materials are widely used by model engineers for the making of sparkplugs. They give a good quality and long lasting alternative to production ceramic plugs.

Shipping

All our plugs are packed in a foam lined plastic box for protection then inserted into a bubble lined envelope for further protection. They are then inserted into an addressed envelope for shipping. I can send them just about anywhere in the lower 48 for a reasonable price so shipping will be $6USD to the lower 48 and $14 to Canada. Any where else shipping will be $1.50 + actual shipping to your door. I don't want to make money on shipping I just want to cover the cost of the packing material.
