Specs At A Glance

Good To Know

Q: How do I know if this gasket needs replacing? A: Symptoms like rough idle, lean codes, or a whistling sound at the intake often point to a failed throttle body gasket. Inspect for cracks, flattening, or oil saturation before reusing.

Q: Can I reuse the old gasket after removing the throttle body? A: Reusing a compressed gasket risks vacuum leaks, so fitting a fresh one during reassembly is the reliable choice. This gasket matches OEM 420950792 for a proper seal.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
