P-RZ7HC/T10 Sparkplug P-RZ7HC

The Champion P-RZ7HC spark plug is designed for the high-revving, small-displacement fours of the mid-80s. This plug is the correct fitment for the 1984 Suzuki GSX 400 FWS, D, and E models, as well as the 1985 Japanese-market GSX-R 400. Champion’s engineering expertise, honed through decades of involvement in racing and aviation, ensures that these plugs can handle the rapid-fire ignition demands of these classic sportbikes. A fresh set of plugs is key to maintaining the sharp throttle response and smooth power delivery these 400cc engines are known for. By choosing Champion, you are opting for a brand with a legendary history of performance. These plugs are sold as a pack of ten, providing plenty of replacements for multiple service intervals.
