Volvo 140 » Spark Plugs
The first suspect in a poor-performing engine seems to always be the plugs.
On the B18/B20 engines the plugs will take quite a beating especially if the engine is a little on the worn side. These engines will usually require a check up and tune about twice a year. Contaminants like oil and incorrect fuel mix will shorten the life of a plug dramatically.
We have been using and selling the NGK spark plugs for about 30 years because they have been the leaders in copper core technology. Copper is a great conductor of electricity and heat and so they perform quite well under all extremes and have a large conductor tip for maximum spark area.
