How Often Should the Spark Plugs Be Replaced on a Volkswagen Tiguan?
2 Answers
Volkswagen Tiguan spark plugs should be replaced approximately every 25,000 kilometers. The function of spark plugs is to introduce high-voltage electricity into the combustion chamber, causing it to jump across the electrode gap and generate a spark, thereby igniting the combustible air-fuel mixture in the cylinder. Taking the 2019 Volkswagen Tiguan 2WD Elite model as an example, it belongs to the compact SUV category, with body dimensions of 4,486mm in length, 1,839mm in width, and 1,646mm in height, a wheelbase of 2,681mm, and a fuel tank capacity of 60 liters. The 2019 Volkswagen Tiguan 2WD Elite is equipped with a 1.4L turbocharged engine, delivering a maximum horsepower of 150PS and a maximum power speed range of 5,000 to 6,000 rpm.
A friend asked me how often to change spark plugs for the Volkswagen Tiguan. It depends on the specific engine. For the older 1.8T Gen2 EA888, it's recommended to change at 30,000 km, but the newer 2.0T Gen3 engine with higher compression ratio requires mandatory replacement every 20,000 km according to official guidelines. My car is a 2020 Tiguan L, and the dealership reminded me to replace spark plugs at the first service. They explained that turbocharged direct-injection engines have high ignition frequency, causing faster wear on the OEM NGK platinum spark plugs. Now I buy the parts myself and hire someone to replace them, saving half the cost compared to dealership service. But you must verify the correct part number - the Tiguan requires 06K905601M. Using the wrong model could cause piston damage!
