The 1988 Champion Spark Plug 400 was the 19th stock car race of the 1988 NASCAR Winston Cup Series season and the 19th iteration of the event.

Taking advantage of a misfortunate Bill Elliott, Ranier-Lundy Racing driver Davey Allison would manage to lead the final 23 laps of the race to take his third career NASCAR Winston Cup Series victory and his first victory of the season.

It is known as a "sister track" to Texas World Speedway as MIS's oval design was a direct basis of TWS, with moderate modifications to the banking in the corners, and was used as the basis of Auto Club Speedway.

Michigan International Speedway is recognized as one of motorsports' premier facilities because of its wide racing surface and high banking (by open-wheel standards; the 18-degree banking is modest by stock car standards).

Bill Elliott, driving for Melling Racing, would win the pole, setting a time of 41.157 and an average speed of 174.940 miles per hour (281.539 km/h) in the first round.
