I recently replaced my old ignition knock sensor with the General Motors 10456288, and I must say it has made a significant difference in my driving experience.

\n\n

The first thing that struck me was the ease of installation. The sensor slid right into place, and the connector pins matched perfectly with those on my existing wiring harness. I appreciate the fact that GM provides an OEM part like this – it means there’s no guesswork involved when it comes to compatibility.

\n\n

The sensor itself seems to be well-built, with a durable housing and sturdy connections. It feels like a quality product, which is exactly what you’d expect from General Motors.

But the real test came when I took my car out for a spin. The engine ran smoothly, without the persistent knocking that had plagued me before. This sensor really does seem to be effective at detecting and reducing detonation, which can save wear on the engine over time.

However, there was one minor issue I encountered. The sensor did emit a brief, high-pitched whine when I first started the car after installation. But this noise subsided after a few minutes, and hasn’t returned since. It’s possible that some debris got trapped in the sensor during installation, causing the initial noise.

\n\n

All in all, I’m impressed with the General Motors 10456288 Ignition Knock Sensor. Its ease of installation, high-quality build, and effective performance make it a worthwhile upgrade for any GM vehicle owner experiencing detonation issues.
