What spark plugs are used in the Haval GW4G15B?

[VanTessa]

Haval GW4G15B uses Champion spark plugs. The Haval H6 is the flagship model of the Haval brand. On August 25, 2011, the Haval H6, positioned as an urban intelligent SUV, was grandly launched at the Great Wall Motors Tianjin new factory, offering Mitsubishi 2.0L gasoline-powered models and Green Power 2.0T diesel models, divided into three versions: Urban, Elite, and Premium. Below is an introduction to the Haval H6: 1. Body dimensions: The Haval H6's body dimensions reach 4640×1825×1690mm, with a wheelbase of 2680mm. 2. Exterior: While retaining the rugged and masculine style of an SUV, the Haval H6's exterior pays more attention to detail design, incorporating more modern technology, fashion, and luxury elements, giving the entire vehicle a handsome and elegant appearance.

The original spark plugs for the Haval GW4G15B engine are standard nickel alloy type, commonly the Torch brand K7RTI3 model. But honestly, I'd recommend upgrading to single platinum or double iridium versions, as this 1.5L naturally aspirated engine runs at relatively high temperatures. During my last maintenance, I switched to NGK BKR6EGP plugs - the throttle response became noticeably sharper, and fuel consumption dropped by 0.3L. When purchasing, make absolutely sure the heat range is 6, thread length is 19mm, and use a 16mm socket - last time my friend forced in wrong plugs and ruined the cylinder head threads. Nowadays e-commerce platforms can match exact models by entering vehicle year. I suggest checking electrode gap every 30,000 km.

As a frequent tinkerer with older Haval models, I've removed and installed the spark plugs for the GW4G15B engine over a dozen times. The factory-equipped nickel alloy Torch K7RTI3 plugs only last about 20,000 km. Later I tried Denso's IK20 iridium plugs - cold starts became remarkably smooth, though they require adjustment with a 0.8mm gap gauge. For hassle-free maintenance, just get Bosch FR7KPP33W plugs with platinum tips featuring anti-carbon-fouling coating. Pro tip: Always perform spark plug replacement when the engine is cold, and remember to apply dielectric grease to the seals - otherwise high-voltage leakage will make your car shake like a massage chair.

For the Great Wall GW4G15B engine used for five or six years, spark plug selection must focus on three key points: heat range must be 6 or 7, thread specification M14×1.25, and thread length 19mm. The OEM nickel alloy plugs cost just over ten yuan, but for high-end models, Torch's K7RTI iridium-platinum plugs are recommended. There's a misconception to correct: more expensive spark plugs aren't necessarily better; for vehicles frequently used for short trips, double iridium plugs can actually lead to more carbon buildup. During replacement, keeping the torque at 25N·m is safest—I've seen apprentices shatter ceramic insulators using pneumatic wrenches.

Just replaced the spark plugs for my wife's Haval H1, same GW4G15B engine. Studied the repair manual - this engine requires resistance below 5kΩ. The OEM part is Torch K7RTI3, but dealerships now recommend NGK 3656 platinum. Personally tested Denso VK20 iridium with best results, but note post-2017 models have modified ignition coil connector shapes. DIY is simple: disconnect battery negative before unplugging ignition coils, use magnetic sockets to prevent dropped screws, and apply anti-seize compound for easier future removal.

Friends who are into Haval modifications should know that the spark plug selection for the GW4G15B engine directly affects power response. The stock nickel alloy plugs feel sluggish during acceleration, so I swapped them out for NGK Racing R7434-9 on track days. For daily driving, I recommend using Bosch FR7KPP33W with a heat range of 7—the iridium platinum electrodes can last up to 80,000 km. A key point is gap adjustment: carbon buildup in the combustion chamber of older cars can lead to excessive gaps, so new plugs should be adjusted to 0.7-0.8mm with a feeler gauge before installation. During my last maintenance, I found that oil seepage from the ignition coil connectors can also cause misfires, a common issue with Great Wall engines.
