What is the spark plug model for the Hongqi H7?
4 Answers
The spark plug model for the Hongqi H7 is ILTR6J8. The purpose of the spark plug is ignition, and during use, the spark plug's electrodes consume electricity through spark discharge from areas prone to discharge. The Hongqi H7 is a high-end sedan from a Chinese independent brand, with body dimensions of 5095mm in length, 1875mm in width, and 1485mm in height, and a wheelbase of 2970mm. In terms of appearance, the Hongqi H7 features dual-tone rear taillights, with lines running from front to back that echo the design of the front headlights. In terms of power, the Hongqi H7 is equipped with two engines, the CA6GV and CA4GC20T, both independently developed by China FAW Group, offering excellent performance and fuel economy.
I've been driving the Hongqi H7 for several years and remember the spark plug model clearly—it should be NGK ILFR6T11, specifically designed for the 1.8T engine. That time when my car had ignition issues, the mechanic diagnosed it as a spark plug problem. After replacing the whole set, the engine ran smoothly again. I suggest checking your owner's manual or the label under the hood to avoid buying the wrong type. Worn-out spark plugs can affect fuel efficiency and power output, even causing engine misfires, so regular inspection is crucial—I check mine every 20,000 km. If replacing them yourself, avoid over-tightening to prevent engine damage. For safety, it's better to have a professional workshop handle it; they can also inspect the electrical system while at it.
After working in the auto shop for a long time, I've noticed that the Hongqi H7 commonly uses NGK ILFR6T11 spark plugs for its 1.8T engine. I've seen many owners choose the wrong parts, leading to difficult ignition after replacement. Although spark plugs are small, they significantly impact performance; when aged, they can weaken power output. Be cautious with torque control during replacement—over-tightening can damage the cylinder head. I recommend purchasing OEM or equivalent Bosch products instead of opting for cheaper alternatives. During routine maintenance, I also remind everyone to check the gap to ensure ignition efficiency. By the way, if there are signs of oil leaks, it might affect spark plug lifespan, so comprehensive maintenance is essential.
When I first drove the Hongqi H7, I didn't know the spark plug model either. After asking the salesperson, I found out it was NGK ILFR6T11. You can directly check the vehicle manual, which clearly states the specifications. Never buy the wrong one and replace it, otherwise the engine will have trouble igniting and the car will be bumpy and difficult to drive. It's best to go to a 4S store for replacement or confirm the model yourself before doing it, so that the car runs smoothly and saves fuel.
