Buick shares its platforms with other GM brands — LaCrosse and Lucerne with Impala and DTS, Enclave with Traverse and Acadia, Encore with Chevrolet Trax — but Buick trims add their own lighting, trim and suspension packages. A large share of the Buick parts we quote are for 1995–2011 LeSabre, Park Avenue, Century and LaCrosse with the 3.8-liter V6, plus classics from the 1960s and 1970s, so year and engine drive the fitment.
What’s different about Buick engine, fuel and ignition parts
- The 3800 Series II and III V6 uses a coil pack with three coils on an ignition module, plus a plastic upper intake manifold that cracks and leaks coolant on the Series II — the intake gasket and manifold are common orders; the supercharged version adds a supercharger coupler and snout bearing.
- The 3.6-liter V6 (LaCrosse, Enclave, Regal GS) is direct-injected on 2009-and-newer models and is known for stretched timing chains on 2007–2011 engines; it uses a high-pressure fuel pump, six coils and iridium plugs.
- Encore's 1.4 turbo (2013–2019) uses a coil pack and is known for PCV valve failures in the valve cover, and the Regal 2.0 turbo uses a high-pressure pump and coil-on-plug; classic Buicks with the 350, 430 and 455 V8 use mechanical fuel pumps and distributor ignition.

What we need to quote your Buick engine, fuel and ignition parts
- Engine code or displacement (found on the emissions label under the hood)
- Any stored trouble codes (P0300-series misfire codes tell us which cylinder)
- Mileage, so we can recommend the service items due at the same time
- Turbocharged or naturally aspirated — plug heat range and gap differ
