Picture this: you're cruising down the highway in your Chevy Silverado or GMC Yukon when that dreaded check engine light flickers on. A quick scan reveals knock sensor failure—common in 5.3L GM engines after years of hard use. Left unchecked, it can mean pinging, lost power, worse mileage, and even costly repairs down the line.
This dual knock sensor kit with wiring harness steps in as the direct OEM replacement. Sensors match specs for part numbers 12601822, 12589867, and 917-033, ensuring plug-and-play compatibility. No guesswork, no cutting corners—the included harness eliminates brittle factory wiring issues that plague these trucks.
Once installed, your engine runs cleaner and stronger. No more hesitation under acceleration, better fuel economy from proper spark control, and peace of mind knowing you've nipped a major failure in the bud. It's especially handy for towing hauls or off-road adventures where engine stress runs high.
Truck owners rave about how this kit silenced their codes and revived performance without dealership prices. Whether you're a weekend wrench-turner or just tired of limp mode, it's the practical upgrade that keeps you moving. Compatible across a wide range of GM full-size SUVs and pickups—check your model year for a perfect match.
