12606260 RME582 Throttle Body for Buick Lacrosse 2.4

12606260 RME582 Throttle Body for Buick LaCrosse 2.4

The 12606260/RME582 throttle body is a direct-fit replacement for Buick LaCrosse 2.4L models, cross-referenced to OE numbers 12606260 and RME582. Manufactured to original-equipment specifications with a 58mm bore, it is engineered for stable idle control, accurate airflow metering, and consistent throttle response.

The throttle body regulates airflow into the engine in response to driver input and ECU commands. Carbon buildup, internal wear, or electronic failure can cause rough idle, hesitation, poor fuel economy, and check engine lights. This unit restores factory-level intake control without adapter plates or wiring modifications, and the 58mm bore matches the Lacrosse 2.4L intake system for proper airflow across the full operating range.

Each unit is batch-manufactured with repeatable tolerances, making it suitable for both individual repairs and volume orders where consistency matters. This unit is positioned for wholesale distribution, repair shop supply, and private-label programs, with OEM and ODM cooperation available.
