Product: 1.8 Pcs Car Ignition Coil Wiring Harness 7mm — for Chevrolet Avalanche, Camaro, Tahoe — No.19297035 Ignition Cable for Car Engines Key benefits Restores reliable spark and smooth engine operation: replaces aged or damaged ignition wiring to stop misfires, rough idle, stalling, and increased fuel consumption. Durable under heat and pressure: housing is made from high-temperature resistant plastic and the inner coil resistance is stable for consistent performance over time. Lower maintenance and operating cost: recommended replacement cycle is 40,000–60,000 km; routine cleaning is usually sufficient to prevent oil and water contamination. What it is Function: ignition coil wiring harness / ignition cable designed to transfer high-voltage from the coil to the spark plugs. Size: 7 mm conductor diameter. Compatibility: specified for Chevrolet Avalanche, Camaro, and Tahoe. Part number: No.19297035. Quantity: 1.8 pcs (as listed). Materials and performance Housing material: smooth, high temperature resistant plastic to reduce thermal aging. Electrical performance: stable internal coil resistance ensures consistent spark energy and helps maintain engine timing and combustion efficiency. Durability: designed to resist aging in high-temperature and high-pressure engine bay environments, extending service life. Why this matters A worn ignition cable reduces ignition efficiency, leading to misfires, loss of power, jerking, and higher fuel use. Replacing the harness restores precise ignition timing and combustion, improving fuel economy and cutting emissions. Stable resistance and heat-resistant housing mean fewer failures and longer intervals between replacements. Typical use scenarios Routine tune-up: replacing old ignition wiring during scheduled maintenance to maintain engine performance and fuel economy. Troubleshooting misfires: when a vehicle shows intermittent misfire codes, rough idle, or poor acceleration, swapping this harness can diagnose and resolve ignition-related faults. Post-repair replacement: install after ignition coil or spark plug service to ensure all high-voltage components are fresh and compatible. Care and installation notes Professional installation recommended if you are not experienced with ignition systems. Incorrect installation can affect engine performance. For daily maintenance, wipe clean of oil and moisture; avoid prolonged exposure to fluids that can degrade insulation. Recommended replacement cycle: 40,000–60,000 km, or sooner if performance issues occur. What it solves Eliminates ignition cable aging-related faults that cause poor combustion, jerking, and increased fuel consumption. Provides a reliable, heat-resistant connection between coil and spark plugs to maintain consistent engine operation. Compatible models (as listed) Chevrolet Avalanche Chevrolet Camaro Chevrolet Tahoe OEM/reference: No.19297035 If you need consistent ignition performance and a durable replacement cable for the above Chevrolet models, this 7 mm ignition coil wiring harness (No.19297035) is designed to restore reliable spark delivery and extend service life with minimal routine maintenance.
