This replacement uses the same OEM precision electroplating process and corrosion-resistant stainless steel, with atomization hole tolerance within ±0.002 mm, matching original standards for long-term use without clogging or leaking. OEM numbers 12633789/12633784, fits Buick LaCrosse produced after 2000 across all variants (including 2.0L/2.4L engines). Functionally, it precisely controls fuel injection quantity to stabilize the air-fuel mix, preventing idle jitter or acceleration surge. Installation/ replacement difficulty is medium; requires removal of the intake manifold and replacement of the seal ring; performed by skilled technicians to avoid high-pressure fuel line leaks.
