The EP-1452 is an electronic distributor for compact GM cars and trucks equipped with the 2.5L 4-cylinder and 2.8L V6 engines, covering Oldsmobile Calais, GMC Sonoma, Chevrolet S10 compact pickup, Pontiac Grand Am, and Buick Skylark across the late 1980s and early 1990s. This application represents the compact truck and front-wheel-drive compact car segment of the GM platform sharing strategy.
The Chevrolet S10 compact pickup with the 2.8L V6 is a particularly common application in this group -- the S10 was GM's best-selling compact pickup through the late 1980s and early 1990s, and the 2.8L V6 was the standard performance option over the base 4-cylinder. Many S10 trucks remain in active service as economical work vehicles, making the 2.8L distributor a continuing parts demand.
Verify the OEM number on your specific vehicle's distributor before ordering, as the compact GM platform was updated several times through the production period and the exact distributor configuration may vary by model year.
