The 3.3 Traxxas engine is a .20ci displacement. The 2.5/2.5R is a .15ci displacement. The Novarossi will outlast a Traxxas engine and will be less temperamental. The 3.3 has a habit of snapping (really they split down the middle usually) a conrod if broken in too cold. Standard glow plugs seal by means of the copper washer. Turbo plugs have no washers - they seal against the head button along the taper on the plug. Turbo plugs make more power because they don't interrupt the combustion chamber shape like standard plugs do. Novarossi Direct sells Nova turbo plugs for about $7 each.
I'm not a fan of OS. Their stuff is so overpriced it's not even funny.
