1988 Firebird Pictures



Again the 1988 Pontiac Firebird remains basically unchanged. 170hp LG4 carbed 5.0L dropped in favor of new 170hp L03 throttle body injected 5.0L. All V8's receive serpentine belt systems and A/C compressors move to passengers side of engine de-cluttering the underhood area. 1988 Pontiac Firebird Formula gets new high tech 16x8" aluminum wheels with silver WS6 centercaps. The 1988 Firebird GTA wheels were slightly restyled. Convex 16" wheels dropped as all Trans Am's get the 16x8" diamond spoke aluminum rims available in different colors such as white, red, charcoal, and black, in addition to the GTA's gold. 1988 Pontiac Firebird GTA recieves new steering wheel with integrated radio controls. '88 Firebird Trans Am made available with body colored ground effects like the GTA. Optional on the GTA was a new "notchback" hatch. Rather than glass the new "notchback" consisted of a fiberglass trunk lid with a flat vertical glass window. The notch back available in the 1988 Pontiac Firebird also incorporated redesigned rear seatbacks with an integral headrest.
