What is the spark plug model for the 2012 New Focus?
2 Answers
2012 New Focus spark plug model is NGK LTR6GP, 1.0T/1.5T engines use NGK iridium platinum spark plug ILZNAR8A7G. Relevant information is as follows: 1. Touch test: Start the engine and let it idle, touch the insulating ceramic part of the spark plug with your hand. If the temperature rises quickly and significantly, the spark plug is normal, otherwise it is abnormal. 2. Short circuit test: Start the engine and let it idle, use a screwdriver to short-circuit each spark plug cylinder by cylinder, listen to changes in engine speed and sound. If the changes are obvious, the spark plug is normal, otherwise it is abnormal.
Oh, I've worked on quite a few 2012 Focus models during my repairs. The spark plug model is usually NGK ILTR5A-13G, especially common for the 2.0L engine. However, I recommend checking the owner's manual first to confirm the specific configuration, as different engine versions like the 1.6L might use Bosch FR8NPP30W. When replacing spark plugs, I usually disconnect the battery cable first, then use a special tool to remove the old ones. The torque for new spark plugs must be strictly controlled to the specified value—don't over-tighten them. Worn-out spark plugs can cause engine shaking, increased fuel consumption, and in severe cases, affect starting. Regular replacement every 30,000–40,000 km ensures smooth ignition and improves driving comfort. Doing it yourself can be fun, but beginners should be careful not to damage the coil or electrodes to avoid repair hassles. In the long run, maintaining good spark plugs saves fuel costs and keeps your car's engine more durable.
