ALL Formulas still Dawned the WS6 Package, with the power Bulge hood & the Trans Am's Aero Spoiler.
1988, only a few changes were made to the Formula, Exterior wise it was almost identical to an 87. The most noticeable difference the Convex Turbo wheels were now available on 88 Formulas. The concave wheels which were used on 87's were available, but it is unknown whether the new convex wheels were an option, or Pontiac decided to use up its supply of 87 concave wheels before using the new convex wheels. There are some pictures with the 87 concave style wheels on 88 Formulas.
The Engine Compartment received a new, more efficient, 170hp Throttle Body Fuel Injection, The LG4 was dropped for the new LO3 TBI, making 1988 the first year for a complete Fuel injection lineup for the F-body. The Engine also received a new upgraded cold air system, and a new serpentine Belt system.
The interior remained basically unchanged, except for a new 120Mph Speedometer replaced the 85 mph one in 87, and a new 4 spoke steering wheel, instead of the 3 spoke "Formula" Steering wheel.
