Review: Excellent Product, Worth the Price? - Don't notice great performance gains. Question is, is it better to go with standard champions at a lower price/change more often, or buy more expensive and try to run longer? Not sure the value is there.
Review: removed the miss and fixed the check engine light - I purchased these plugs for my fathers 2000 mercury gran marquis. it only has 70000 miles on it and he was getting a miss and check engine light. I replaced the plugs and reset the engine light. We have had no more problems with his car. I have not checked the fuel mileage but I am sure it is getting better mileage without the miss and hesitation. I would recommend these plugs.
