Thank you for that outstanding bit of mechanical knowledge, it has proven most helpful to me and to others on this board I'm sure. I think most people would agree that a set of plugs and coils is what is commonly referred to as a tune up kit for those of us not as technically proficient as the previous poster. I have found several of these "non existent" kits on line which vary in price and content. I've already replaced the air filter, fuel filter, and oil filter earlier this week when I did the oil change. I'm mostly concerned with finding a set of Motorcraft plugs and coils (Motorcraft or otherwise) at a decent price. Most kits include Motorcraft plugs and some kits have Motorcraft coils but most use after market. I've owned every body style of truck since 1975 but this one is the most sensitive one I've ever owned which is why I'm seeking knowledge of anyone who has experience with any of the different kits out there, particularly brand of coil. I only need plugs and coils at thispoint but if I find a good deal on a kit with all these items, it wouldn't kill me to buy it and save them for later use. Thanks to anyone who can give some helpful input.

when you say you have an 04 FX4 truck, I am going to assume it is a new body style with the 3 valve engine.
while there is no tune up kit per say, I am sure some retailers will bundle the required parts and sell as a "kit"
From my personal experience, Motorcraft plugs seem to work the best and last the longest.
Regardless if you have a 2v or 3v engine, I see no need to replace the coils as regular maintenance. I do however recommend replacing the coil boots when replacing the plugs, along with a moderate dab of di-electric grease on either end to prevent corrosion.

My apologies for not being thorough. Yes it is the 3v and I don't have much experience with this cop set up. I have a 98 that I owned for 5 years so far and only replaced plugs once last year and 1 coil because it was running like crap. That truck seemed to have so much more power than this one so I was thinking it might have a weak spark or something. I'll try looking for a bundle deal with just those items. If you know where to get a good deal please let me know. Thanks for the input.

There are several ebay sellers who bundle Motorcraft plugs and coils for around $100, usually with the ad copy worded so the casual reader doesn't realize the coils aren't Motorcraft.

If it's a 3 valve, you should also invest in a spark plug extraction tool. If the plugs have never been replaced, you will probably break one or two and the broken part will remain in the head. I take my 06 5.4 to the dealer to change the plugs because I can't afford the down time to extract a broken plug and the dealer has the tools and know how to do it.

You can do a search on e bay, amazon, or a Google search. Several bundled "kits" pop up. Some include air filter, fuel filter, pcv, plugs, coils, or a combination of these items. I can get you links of you need them but the are quite a few which is why I was hoping someone here had used one and could offer some insight on their experience and where I could get a good deal on them. I have received some good input so far and I'm leaning toward just replacing new Motorcraft plugs and the boots. If anyone has a good source for a set, I'd appreciate it. Thanks for all the replies.
