Select the trim of your vehicle below

The 2003 Cadillac CTS is the introductory year for this compact luxury executive car. It is filled with all of the amenities you would expect from Cadillac, and you still use yours to take your clients to meetings and job sites. When you need new parts for your CTS, you only buy OEM Cadillac parts for exact fit replacement parts that never need modification.

Air Filters – The air filter on your vehicle keeps fresh air circulating throughout the engine, and if the filter becomes clogged, your engine will not run properly. We have filters, hoses and other maintenance parts.
Alternators – The alternator keeps the battery charged, and should this part fail, you may not be able to keep your engine powered. We have alternators, starters and other electrical parts.
Brake Pads – When you press the brakes, the pads are pushed against the surface of the rotor. This causes pads to wear out. Check your brakes for wear and replace worn brake parts like the pads, rotors and calipers.

When you buy your OEM Cadillac parts from us, you get our price match guarantee on genuine GM parts and no hassle returns. Shop now.
