Used to use OS8s in my hobao mach28 powered monster truck. Tried these and never looked back. Engine starts better and responds to tuning better. Great plug. Fabulous service from modelsport too, as always!

Great item, one of the most important parts of the engine, bad glow plug just make running these car a nightmare. Fitting a plug like this make them a joy to own and run. Thanks ModelSport
