It never pays to clean the old ones

It may cost more money to clean and re-use the old ones. Engine peformance may suffer and decrease gas milage.

Four spark plugs only cost less than $30 and can last 3 years or longer. Why bother with cleaning?

think about it average car uses cost $1500 on gas, if your engine suffers 5% due to old plugs, it cost you more.
