Hi, I am just learning about the distributor less coils and I have a 2000 Grand Marquis. I am wondering about what brand would work the best. I dont need anything for performance I just want to do a tune-up and figured while I am at it I will change them as well. What brand do you recommend and about how much is it going to cost for all 8 of them? What kind of spark plugs should I get? I want to do an all around tune-up and want to make sure I dont miss anything. What else do you suggest that I do? It has just over 107k miles on it and I bought it about a year ago. I have done a tranny flush and new filter but other than just your regular oil changes and I havent done much else. Any suggestions on things that I should do would be appreciated. I know the basics about cars but wouldnt be able to tear an engine apart anytime soon.
