VG1238080015 is the premium Howo/Sitrak truck parts ignition solution engineered for extreme durability and flawless spark delivery. This OE-grade ignition coil assembly directly replaces the original unit, restoring engine power, reducing misfires, and improving fuel efficiency across all Howo and Sitrak heavy-duty models. Whether you operate a fleet of Howo dump trucks or Sitrak long-haul tractors, this VG1238080015 ignition coil ensures consistent combustion even under high-vibration, high-temperature conditions. With precision-wound copper windings and a robust epoxy encapsulation, it withstands moisture, dirt, and thermal shock – delivering reliable starts and smooth acceleration mile after mile. Our VG1238080015 coil is tested to meet or exceed OEM specifications, making it the smart choice for workshop owners, fleet managers, and independent mechanics who demand zero-compromise quality.
The ignition system is the heart of any diesel or spark-ignited heavy-duty engine, and the VG1238080015 coil assembly is designed to keep that heart beating strong. Unlike generic aftermarket coils that fail prematurely, this Howo/Sitrak-specific unit features a high-energy silicon-steel core and secondary winding ratio optimized for the high compression ratios found in commercial truck engines. Every VG1238080015 coil undergoes a strict four-stage quality check: resistance testing, insulation voltage breakdown, thermal cycling (-40°C to 150°C), and vibration endurance. The result is a component that delivers a consistent 40kV spark, even when the engine is lugging under full load. Operators report up to 12% improvement in cold-start reliability and a noticeable reduction in unburnt fuel, which directly translates to lower emissions and better MPG.

Moisture & vibration proof
Direct replacement, no adapter needed
Reduces unburnt fuel waste
Optimised for electronic ignition
Howo and Sitrak trucks are built to conquer the toughest terrains – from mining roads in Australia to frozen tundras in Siberia. The VG1238080015 ignition coil assembly is engineered with the same relentless spirit. Its housing is made from high-temperature PBT plastic, reinforced with glass fibre to prevent cracking under constant engine shudder. The primary and secondary windings are copper-wound and vacuum-impregnated with a special varnish that eliminates void formation, a common cause of internal arcing. We also add a ferrite core that stabilises inductance over the entire RPM range, ensuring that spark energy remains constant whether you are idling in traffic or climbing a steep grade at 2100 RPM. Over 500,000 on-road test miles have validated the VG1238080015 design, with zero coil-related breakdowns reported in the trial fleet.
This VG1238080015 coil assembly is the direct OEM replacement for numerous Howo and Sitrak engine families, including the MC07, MC11, MC13, and the WP series. It also supersedes older part numbers such as VG1238080014, VG1238080016, and various aftermarket codes. The connector is a standard 4-pin Delphi type, with terminal locking that ensures a vibration-proof connection. The mounting holes are precisely machined to match the cylinder head bosses, and the included O-ring gasket provides an oil-tight seal. Always verify your engine serial number and original part number, but in most cases, the VG1238080015 is the universal upgrade for all post-2015 Howo/Sitrak 6-cylinder and 8-cylinder engines.

Replacing the VG1238080015 coil is straightforward for any experienced mechanic. Ensure the battery is disconnected, then remove the electrical connector and the two retaining bolts. Clean the mounting surface thoroughly – any dirt or oil can cause improper seating. Install the new coil with the supplied bolts torqued to 12 Nm. Reconnect the harness and use a dielectric grease on the terminal to prevent future corrosion. After installation, reset the engine control module (ECM) to clear any stored misfire codes. A quick test drive will confirm smooth acceleration and stable idle. For best results, inspect the spark plug boots and replace them if they show cracks or carbon tracking. The VG1238080015 coil is maintenance-free for the first 300,000 km under normal service, but periodic visual inspection of the connector and housing is recommended.
If you experience any of these symptoms, the VG1238080015 coil is the direct, premium solution that restores your truck’s performance immediately.
Every VG1238080015 ignition coil assembly leaves our facility with a certificate of conformance. We employ a 100% final test that includes: high-potential insulation testing at 45 kV for 5 seconds, inductance and resistance measurement with a precision LCR meter, and a functional spark test under simulated engine conditions (using a variable reluctance sensor and ECU signal generator). The coil is also subjected to a 30-minute thermal soak at 120°C while continuously firing a 20 mm spark gap – this ensures no degradation in energy output. Our in-house laboratory follows ISO 16750 standards for environmental compliance, so you can trust the VG1238080015 in any climate, from the humid tropics to arid deserts.
Yes, this coil is designed for 24V truck systems (common in Howo/Sitrak) and includes an internal current-limiting circuit to prevent overheating during prolonged dwell.
Absolutely. The VG1238080015 is backed by a 12-month or 100,000 km warranty against manufacturing defects – whichever comes first.
While the connector and physical dimensions are standard, we strongly recommend using it only with Howo/Sitrak or engines that cross-reference the OEM number, as ignition timing and dwell parameters are optimized for these ECUs.
