My brother has an 04 F150 and told me all about the nightmare that was spark plug replacement (and coils). He bought everything from autozone and spent $12 per plug and $50 per coil. Now, a buddy of mine is running into the same issue. Same 2004 with 110,000 miles and it started missing on him the other day and our hunt starts Saturday. So I get to reading up on the spark plug change procedure and apparently it's a real PITA. Couple Q's.

1. When I get on Rockauto.com some plugs look like normal plugs and are $2 each and others look like they go on a Star Wars hover vehicle and are $7 each. Do we really have the option to use the regular ole $2 plugs?

2. Rockauto.com also has coils for $10 up to $45 each. Is there a $35 difference in coil quality?

3. What is this tool I keep reading about? Can't seem to find a description or pic.

 

1. Use OEM parts. yes it is a PITA. If you use cheap, aftermarket parts, you will probably have to experience the "PITA" again soon. I used Motorcraft plugs on my '04 at 110,000 miles. Had no problems. Had a bad coil at 255,000 so I went ahead and changed COP's and plugs then.

2. Yes.

3. Lisle part number 65600. "Broken Spark Plug Remover for the Ford 3 Valve". Follow the instructions to the letter.


Best of luck.
