The complete official UK range of NGK and Champion Spark Plug caps or connectors, sometimes called boots or shrouds. All parts are kept in stock subject to manufacturer availability. NGK caps are mostly made from phenolic resin, a type of plastic similar to bakelite. Champion caps are made from silicone rubber.
We have straight and angled caps, with and without resistor, suitable for spark plugs with solid terminal, removable terminal or exposed threaded terminal. Also some special NGK racing plug caps for use with specific racing spark plugs. A spec sheet is included with the product images for each NGK product.
