Did you know that a bad or poor spark plug can reduce your engine’s performance or even destroy the catalyser?
It often happens that a defective spark plug does not ignite the fuel mix in the cylinder, the engine then runs irregularly and this reduces its power output. Unignited fuel can even end in the catalyser and can irrevocably damage it. It is therefore necessary to comply with the replacement interval for spark plugs and igniters. In addition, it is a good idea to entrust a replacement to experts at authorised Škoda service partners that guarantee you correct installation, tightening torque and replacement intervals.

The quality and design of spark plugs determines the performance of the engine and its reliability. A correctly set spark plug positively influences the combustion process of a petrol engine and thereby the volume of waste products in emissions. A spark plug also has an effect on the starting of the engine, its performance and service life and also its consumption of fuel and the composition of exhaust gases.


Engines of the latest generation are fitted with Longlife type spark plugs in Škoda cars. The special materials and top quality technology used during their production guarantee the best functioning of a spark plug and thereby shift the replacement interval for the Octavia RS model to 90,000 km. The quality and design of spark plugs determines the performance of the engine and its reliability.
