How to replace Audi spark plugs?
Replacing an Audi spark plug after every 40k miles is standard. To do the replacement, you will need a new spark plug and ignition coils, spark plug gap tool, flat head screwdriver, ratchet with extension, T30 Torx screwdriver, anti-seize, and 5/8” spark plug socket.
Step-1: Disconnect the ignition coil electrical harness First, open the vehicle’s hood and remove the engine cover—start pulling the plugs located at the bottom of the harness. You’ll find the harness is attached to the engine body. So, remove the Torx screw to detach it. Now you have to push the clips on the coil plugs and take out the ignition coils.
Step 2: Remove the ignition coil and spark plugs As you have already taken out the harness, you can easily take off the ignition coils as well with a little wiggling. Now at the bottom, you’ll find the spark plug. Take the rachet with an extension and attach it to the plug. With the extension, you’ll be able to loosen and pull out the plug from the engine.
Step 3: Install new ignition coil and spark plugs Now, carefully install the spark plug by checking out that they actually fit the engine. Tighten the plugs using your hand and ratchet. Neither makes it too tight nor too loose. Finally, put back the ignition coils and harness in the same you had taken them out. And you’re done!
Best Spark Plugs For 2.0 TSI Buying Guide
After reading all these reviews, you may start to feel confident about buying a spark plug for your vehicle. But it’s better to be entirely sure about what you actually need and what to consider for a spark plug before making the final decision!
Considering the material is very important while buying a spark plug because spark plugs are related to creating sparks through ignition. The process can damage the plug and then the engine if the material is of low quality.
If your vehicle’s engine represents a low-voltage ignition, then plugs made with copper will be the right choice. But for modern and high-voltage engines, platinum and iridium will be more suitable. However, try to choose the plug that is specified by the manufacturer of your vehicle.
Size is another vital factor to consider because different vehicle suits different sizes of spark plugs. You can’t just buy any size and expect to make it fit into your engine. Some standard sizes of spark plugs are 10mm, 12mm, 14mm, and 18mm.
- Heat range
A spark plug can either be classified as hot or cold. A hot spark plug means it can insulate better heat. On the other hand, a cold spark plug means it can produce extra coldness and lower the temperature. Generally, the heat range is specified by the manufacturer. However, if the range will be hot or cold varies from brand to brand.
- Gap style
Spark plugs must have a certain amount of space between the electrode of each spark plug and the center. A gap of 0.6mm or 1.8mm is typically considered as ideal, and the amount of gap depends on the types and brands of the vehicles. However, you can also adjust the gap by using a plug gapper tool.
Durable and long-lasting spark plugs are always preferable. Because without a spark plug, the engine won’t start, and the vehicle won’t run. So, if the spark plug you use gets damaged or worn out frequently, then it’ll be extra trouble for you, especially during emergencies. That’s why always choose the spark plug wisely by being sure about its durability. Even though if the spark plug has gone bad, you can make it reusable.
No matter what you think, or what people say, brands do matter. Most of the time, the overall quality depends on the brand. Even though a spark plug is a very tiny piece of equipment, still the brands have a crucial impact on it. We have tried to shortlist some best spark plugs for 2.0 TSI from the most renewable brands. So, you better consider the brand first and then make the purchase.
Always consider and research the price no matter how small a product you buy. It’s never wise to pay the price for something that is not worth the amount you pay. Generally, the cost of spark plugs ranges from $1-$15. Although it can also vary based on the brand and features.
Is the 2.0 tsi reliable?
Yes, 2.0 TSI or Volkswagen (VW) engines are reliable with a high-reliability test score. However, there is always some weak point that exists. Some models suffer from early engine failures, produce loud noises, and rough running, and create vibration, water, oil pump leaks, etc. Often it makes the car stop and acts as a dead engine in the middle of the road. But these bugs are prevalent and can be solved easily unless something serious happens. But besides everything, usually a 2.0 TSI provides outstanding performance, and many people prefer it,
What spark plugs do Audi use?
Getting the right spark plug for Audi isn’t very difficult. But as an Audi vehicle is costly, everyone struggles much to find the most suitable one. So here is the list of some spark plugs that Audi uses and you can use them without any worry.

How long do NGK iridium plugs last?
The lasting capacity of NGK iridium plugs varies within the models and constructions. For instance, an Iridium plug of NGK with a traditional nickel ground electrode is expected to wear out faster. They have an average of 40-50k miles of capacity. However, it can also change depending on the motor modification and driving condition. With these alterations, a spark plug with a nickel ground electrode can last for 60-80k miles.
On the other hand, iridium spark plugs of NGK with platinum ground electrodes last longer than other ordinary plugs. They have an expected life of 80-100k miles.
What’s the difference between 2.0 TFSI ultra and 2.0 TFSI?
The 2.0 TFSI supports sporty driving. With the new A4 Sedan, you can sprint up to 100 km/h in just 5.8 seconds. There’s also an electronic limit on the top speed, which is 250 km/h. With the Sedan and S Tronic, this engine needs only 5.7 liters of fuel for each 100km, and the CO2 emission is 129g/km.
On the other hand, 2.0 TFSI Ultra provides an agile performance by accelerating 100 km/h within 7.3 seconds. For Sedan and Avant, the top speed is 210 km/h within 7.5 seconds. Also, for 100 km, it needs 4.8 liters of fuel, and the CO2 emission is 114g/h.
Should I use a hot or cold spark plug?
The difference between a hot and cold spark plug is, that the hot plug has a hotter tip, and the cold plug has a cooler. If your vehicle has a high-performing engine, then you should go for cold spark plugs. To ensure high performance, the engine gets very hot, and the spark plugs must control that heat. The cooler tip then balances the heat through the engine’s head.
On the other hand, if your engine doesn’t provide the heat you need to start the engine or have a better performance, then a hot spark will save your day by producing more spark and transferring it to the engine. It also depends on the weather and which plug you should use. On a cold day, go for a hot plug and vice versa.
How can I clean my spark plugs?
It’s needless to explain the crucial role of a spark plug to run your vehicle. And every critical thing requires extra care. However, it’s better to replace the spark if it seems very old, dirty, or worn out. Keeping it clean will definitely buy you some extra time until you manage to get a new one. So, here is how you can clean your spark plugs.
To clean the spark plug, you need to remove it first. Follow the replacement procedure we have mentioned above to remove it. Now, use a brush to clean any liquid-clogged dirt. You can also use a spray-on plug cleaner. If the dirt is too stubborn, then use a pocket knife and carefully take out the disposals. However, while cleaning, make sure you don’t damage anything else inside there.
Spark plugs make us realize that even a small item can cause trouble when deciding to buy it, especially when it bears great importance. That’s why we have tried to sum up some best spark plugs for a particular engine with all of our knowledge, understanding, and expertise. We hope that the reviews above will be helpful to you, and that you’ll be able to choose the spark plug that perfectly suits your vehicle
