Store's Description

If you are looking for spark plugs for vintage or veteran cars, you've probably come across the Green Spark Plug Company. This company specializes in vintage and veteran spark plugs, including period-style plugs and modern replacements. Founder Tim Green has been an avid fan of vintage Morgan three-wheelers since his teenage years, when he had one of his own. Although he eventually switched loyalty to JAP-powered Morgans, he still maintains several cafe racers.
