We all carry a spare ready-gapped spark plug set with us when we're riding away from home, its almost as important as a good puncture repair kit! But how do you ensure that they dont end up battered to death in your tool kit/luggage?
Spark plugs are suprisingly delicate pieces of kit and from experience I can tell you that after three weeks hard riding if they are not properly looked after they can be less than useful when the need arises.
These spark plug holders are small, unobtrusive, cheap, and will ensure that when you need it your spare 'plug(s) will be as fresh as day they were put lovingly into storage.
(price is for one spark plug holder only!)
