If 2 are bad, the rest might be on their way out. Don't waste your money on the ebay seller uneeeek. Those coils are complete crap. I went through a total of 18 coils and plugs from them before I became completely fed up and returned them all.

This guy has them used for $9 each. That's your cheapest option.

That is who I bought mine from, and he works with you. I bought 8 at a discounted rate and so far so good.
Hope that helps.
