rbs5 .21 and rossi px5 .21???
can you guys please tell me if any of these line of glow plugs are best suitable for these engines. my hobby store only carries these two brands; mccoys and os plugs. a3,a5 etc and not sure which type of mccoy plugs sorry. any suggestions would be very helpful. oh and i run in the midwest and it stays pretty warm out here. thanks so much guys, i'm leaving for a race this weekend and really need to pick some up!
