What is the spark plug model for Tiggo 5x?

[VonAyla]

The spark plug model for Tiggo 5x is LDHDIPZU, and its brand is Leidun. The spark plug is a crucial component of the gasoline engine's ignition system. It introduces high-voltage electricity into the combustion chamber and generates a spark by jumping across the electrode gap, thereby igniting the combustible air-fuel mixture in the cylinder. The spark plug is installed on the side or top of the engine. In earlier models, spark plugs were connected to the distributor via ignition cables. However, over the past decade, most car engines have been modified to connect the ignition coil directly to the spark plug. Working principle of spark plugs: The ground electrode of the spark plug is connected to the metal shell, which is then attached to the engine block through the cylinder head threads. The insulator primarily serves to isolate the metal shell from the center electrode. The terminal nut is the part of the spark plug that contacts the high-voltage coil. When current passes through the terminal nut and the center electrode, it breaks down the medium between the center electrode and the ground electrode, generating a spark that ignites the air-fuel mixture in the cylinder.

I've run an auto repair shop for over 20 years, and changing spark plugs for the Tiggo 5x is extremely common. The naturally aspirated 1.5L engine usually comes with NGK DCPR7EIX iridium-platinum spark plugs (heat range 7), while the turbocharged 1.5T version mostly uses NGK SILKR8A7S. I remember one customer who arbitrarily replaced them with ordinary nickel alloy spark plugs, resulting in violent cold-start shaking like a sieve - it only stopped after switching back to OEM-spec plugs. Recommended inspection interval is every 40,000-60,000 km. During replacement, use a 16mm magnetic socket for installation/removal, and applying anti-seize compound on threads is advisable. For vehicles older than 3 years, have your mechanic measure the ignition coil resistance values too - simultaneous failures aren't uncommon.

Last year, I just replaced the spark plugs for my Tiggo 5x after thorough research. The 1.5L version comes with NGK DCPR7EIX as standard, and you can find matching options on e-commerce platforms by searching the model year. Key reminder: buy the resistor-type ones to avoid interference with the car radio. For DIY, prepare a spark plug wrench and torque wrench, and don’t yank the wiring harness when removing the ignition coils. The most reliable method is to check the part number in the maintenance manual, as there may be variations between batches. For my replacement, I chose Bosch FR7HE2+ with copper core, costing about 30 yuan per piece, and saw a fuel consumption drop of around 0.3L after replacement. Disconnecting the negative terminal of the battery before starting is a life-saving step.

Auto parts market veteran advice: To check spark plug model, directly provide the VIN. Tiggo 5x commonly uses NGK DCPR7EIX or Bosch FR7HE2, with iridium tip diameter of 0.6mm. The 1.5T model must use the specialized SILKR8A7S, which has a higher heat value of 8. NGK or Denso brands are recommended, as off-brands may easily melt the electrodes. When replacing, ensure the thread lengths of old and new spark plugs match, as even a 1mm difference can potentially damage the valves.
