Usually the bolts snap, those manifolds won't break, their pretty heavy cast. But the bolts, - yea, they always snap, specially in the rear by the firewall.
Hello JBrew, I know you were one of the first guys to use the Champion plugs, what exactly happened, they all started miss-firing? Also you mentioned something about heat ....."Yes but Champions can't disburse the heat correctly, therefore STILL a mistake to run in these modulars. Post up when you get your first misfire, lets see how long they last you." ..... I'd like some insight, I've never heard anything about heat-range. Regards, Ed
