Spark Plug Cover – Water-cooled Triumph twins 2016 on

We see a lot of miss-fire issues with modern Euro4 and Euro5 Triumphs causing stalling or poor running at low speeds. This can result in fouled or burn out spark plugs.

We now replace the stock caps with high quality ( and cheaper) NGK caps, we also recommend using NGK Laser Iridium plugs (see our other listings for these). In the vast majority of cases fitting these will give a huge improvement to the above issues.

Please note that you will need to reuse the OE cap rubber that fits into the head as this is a special size.

Sold individually. 2 cylinder bikes require a pair, if you’re not ordering as a replacement, please select a quantity of 2.

Please note these come in Black, not Red as pictured.
