This kit supplies two pre-calibrated sensors plus a corrosion-resistant harness engineered to meet OE fit and signal expectations for late-1990s through mid-2000s Chevrolet, GMC, Cadillac, Hummer and related models.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this kit restore engine performance?\u003c\/h3\u003e\n\u003cp\u003eThe sensors convert vibration from combustion events into voltage signals the engine control module uses to adjust timing. Worn or damaged sensors, or corroded harness connections, can produce weak or noisy signals that prevent correct timing adjustments. Replacing both sensors and the wiring harness returns the system to reliable signal levels so the PCM can manage knock control properly.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eIncludes two calibrated knock sensors matched for GM V8 engines.\u003c\/li\u003e\n  \u003cli\u003eWiring harness uses tin-plated and solid-brass terminals for strong conductivity.\u003c\/li\u003e\n  \u003cli\u003eFactory-style connector shapes and lengths for direct installation.\u003c\/li\u003e\n  \u003cli\u003e100% accelerometer vibration testing ensures signal durability under stress.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWill these sensors fit my vehicle?\u003c\/h3\u003e\n\u003cp\u003eThis kit supports many common GM platforms equipped with 4.8L, 5.3L and 6.0L engines produced between about 1999 and 2007.
