2002 Buick Regal Parts

Before ordering anything for a 2002 Buick Regal, confirm the engine: our records list 2 variants (3.8L V6, 3.8L V6 Supercharged), and many of the 2,478 parts fit only one of them. The engine code is on the emissions label under the hood if you're not sure — then pick a category below and filter to your engine.

Every part carries its brand and manufacturer part number, so you can compare OEM-grade and aftermarket options for the same fitment and cross-reference the number against the part you're replacing before anything goes in the cart.
