Darren B from Tiverton, RI said, "Received in short amount of time. Product was packaged with all required gaskets and new bolts for lower collector. One lower collector bolt required shortening to prevent contacting header before tightening. Installed header allowed good access to all mounting bolts except one, could only reach with open end wrench, unable to use torque wrench. Intake manifold requires removal allowing excellent opportunity to inspect fuel injector tips and clean intake runners. This was also a good time to replace a broken motor mount that was found with everything out of the way. This header was installed on a 1992 Jeep Cherokee with 275,298 miles. Throttle response and torque has improved."
