If your spark plugs or spark plug wires are damaging or erstwhile, you will experience poor performance and reduced power. In some extreme cases, your engine will have trouble starting or continuing to run. Worn spark plugs and plug wires can cause clogged catalytic converter or damage to ignition coils and O2 sensors, finest to more expensive repairs.

The price of a new one depends on the type of VW you drive, but check our prevailing service coupons and specials.

If there is excess oxygen in your exhaust system, fuel burns faster and your car will be less direct when it comes to fuel economy. So what happens if I don’t replace your O2 sensor? A faulty sensor can not only affect your miles per gallon, but it can cause damage to your catalytic converter and your 2020 VW Jetta GLI's spark plugs.
