What brand of spark plugs does the Audi Q5 use?

ACDelco Iridium Spark Plugs. The replacement interval for Q5 spark plugs is 20,000 kilometers. Here is some information about spark plugs: 1. Function of spark plugs: The function of a spark plug is to release the pulsed high voltage sent from the high-voltage wire (spark plug wire), break down the air between the two electrodes of the spark plug, and generate an electric spark to ignite the air-fuel mixture in the cylinder. Main types include: standard spark plugs, extended insulator spark plugs, electrode-type spark plugs, seat-type spark plugs, pole-type spark plugs, and surface-gap spark plugs. 2. Working principle of spark plugs: Under the effect of high voltage, the air between the center electrode and the side electrode of the spark plug rapidly ionizes, forming positively charged ions and negatively charged free electrons. When the voltage between the electrodes reaches a certain value, the number of ions and electrons in the gas increases like an avalanche, causing the air to lose its insulating properties and forming a discharge channel in the gap, resulting in a "breakdown" phenomenon. At this point, the gas forms a luminous body, known as a "spark."
As a friend who has driven several Audis, I think the spark plugs for the Audi Q5 are quite particular. NGK or Bosch brands are generally recommended, especially the laser-welded series from NGK, which is used as original equipment on many Q5 models, such as the 2018 and 2020 models with the 2.0T engine. When choosing, it's crucial to check the spark plug specifications to match the engine model. Audi has strict requirements for this; getting it wrong can cause misfires or affect fuel consumption. It's recommended to inspect them every 60,000 kilometers or so. If you notice the car shaking or slow acceleration, it's likely time to replace the spark plugs. If you're replacing them yourself, it's important to buy genuine products. Don't cut corners by going for cheap alternatives. NGK spark plugs are not expensive, costing just a few dozen yuan each at auto parts stores, and they're more reliable, saving you the hassle of future repairs.
I've worked in repair shops for over 20 years and have encountered plenty of Audi Q5 models. For spark plug brands, I generally stick with NGK or Bosch, depending on the engine year. For example, 2015-2020 gasoline models often use NGK IRIDIUM IX series, while diesel versions might come with Bosch's bimetal type. Always check the manual or consult a professional shop before replacing to ensure compatibility—getting the wrong model can cause issues. Spark plugs typically last around 50,000 to 70,000 kilometers. Worn-out plugs can lead to engine shaking, increased fuel consumption, and compromised performance and safety. DIY replacement is possible if you have the right tools, but be careful not to force them—stripping the threads could mean costly repairs. Proper maintenance keeps your Audi running smoothly, saving you money and hassle in the long run.
As a car enthusiast, I've tried replacing the spark plugs on my Audi Q5 myself and found that the original ones often use NGK or Bosch brands, with NGK being particularly common in the 2.0T engine, such as the model IZFR6J. When choosing a brand, make sure it matches your car's year, otherwise you might experience issues like difficulty starting or a sudden increase in fuel consumption after installation. Generally, they should be replaced every 60,000 kilometers. If they're worn out, performance drops noticeably, so don't overlook this for safe driving. Just buy genuine parts yourself—they're not expensive. NGK spark plugs cost less than 100 yuan each on Amazon.
