CHENHO Dual Knock Sensor Kit with Wiring Harness & Intake Manifold Gaskets for 4.8L/5.3L/6.0L GM V8 (1999–2007) — 2 Sensors, Tin‑P

Complete replacement kit that includes two knock sensors, a sensor wiring harness, and two intake manifold gasket sets engineered to restore proper knock detection and sealing on GM 4.8L/5.3L/6.0L engines.

This CHENHO kit bundles precision-tested knock sensors, a durable tin-plated brass-terminal harness, and high-grade rubber intake manifold gaskets to deliver an OEM-style fit for many Chevy, GMC, Cadillac, Hummer and related models from 1999–2007. Every sensor undergoes accelerometer vibration testing and the harness uses corrosion-resistant terminals so the assembly can tolerate engine heat, vibration, and road conditions. The kit replaces multiple OE part numbers for a direct swap without system modifications.

Which vehicles and engines will this kit fit?

It’s designed for GM trucks and SUVs equipped with 4.8L, 5.3L, and 6.0L V8 engines in model years generally between 1999 and 2007. Common compatible vehicles include Chevy Silverado, Tahoe, Suburban, GMC Sierra, Yukon, Cadillac Escalade, Hummer H2, and some Isuzu i-Series models. Always verify your engine displacement and year before purchasing to ensure exact fit.

• Fits 4.8L/5.3L/6.0L GM V8 engines (1999–2007 range)
• Common models: Silverado, Sierra, Tahoe, Suburban, Yukon, Escalade, H2, Isuzu i-Series
• Replaces OE numbers like 12601822, 213-3521, 89060413 and others
• Check vehicle engine size and VIN for precise compatibility

How does the kit improve reliability versus a single-part replacement?

Replacing sensors, the wiring harness and intake gaskets together addresses related failure points that often produce knock codes or vacuum leaks. The package approach reduces the chance of repeat failures caused by a worn harness or compromised manifold seal and shortens repair time because you have all necessary pieces in one box.

• Two sensors included for full cylinder coverage
• Wiring harness with tin-plated brass terminals for corrosion resistance
• High-grade rubber gaskets to prevent manifold vacuum leaks
• Prevents common false knock codes from wiring or seal failures

What quality checks and protections come with this CHENHO kit?

Each knock sensor is tested using accelerometer vibration procedures to ensure accurate response under harsh engine conditions. The harness terminals are solid brass with tin plating to maintain conductivity and resist corrosion, while the gaskets are molded from durable rubber to hold seals under thermal cycling. CHENHO backs the kit with a 24-month warranty covering defects or non-functioning parts.

• 100% accelerometer vibration testing on sensors
• Solid brass, tin-plated harness terminals for longevity
• Durable rubber intake manifold gaskets for long-term sealing
• 24-month replacement or refund warranty and support

How difficult is installation and what does the kit include?

Installation is straightforward for anyone with basic mechanical experience and standard hand tools; the kit is intended as a direct replacement that integrates with existing engine management systems. It contains two knock sensors, one sensor harness, and two intake manifold gasket sets so you won’t need to source additional parts for a complete front intake service.

• Complete contents: 2 knock sensors, 1 wiring harness, 2 intake gaskets
• Direct OE-number replacements—no splicing or modification required
• Installation saves time versus buying parts separately
• Follow vehicle-specific torque and routing instructions for best results

Who is this for: Technicians, DIYers and fleet owners maintaining GM 4.8L/5.3L/6.0L engines seeking an all-in-one, OEM-compatible solution for knock sensor and intake manifold gasket replacement. It’s especially useful for addresses recurring knock codes, harness corrosion, or intake leaks where replacing all related components at once prevents repeat trips to the shop.
