This is an exhaust manifold for DOHC Fiat engines, designed as a 4-2 style. It was originally fitted on 1978-80 Fiat 124 with EGR control.
The manifold has been modified to remove the EGR extension, and to plug the EGR port. The next best thing to a true "1800" manifold. It is an efficient manifold and a great upgrade on all DOHC engines that do not require pollution control.
Excellent condition, all studs are intact. Unit was media blasted, mounting flanges belt-sanded straight. Please note, one or more of the stud holes may be repaired with M8x1.25 Thread-Sert threaded inserts (not Helicoil).
