Just make sure you get all that debris out the chamber after doing. If you don't, that may be a critical mistake. The vacuum method is good for removing the majority, - doesn't always work well enough tho. Specially if the debris was or has been saturated. You should follow up w/compressed air before breaking them loose. A long blow nozzle works best as well.

 

I found using a spark plug socket with the little hole in it at the very top and a 3/8 to 1/4 in adapter with the little ball in it held the extension/adapter to the spark plug socket and the 1/4in extension togeather. I also used a heavy long nose needle nose pliers to get the spark plug socket off when it was stubborn. Got it cheap @ HF. I also had a friend weld a 3/8 short, 4in, extension to a spark plug socket. Suggest obtain a thread chaser for any COP bolts that won't tighten down and new bolt. HF carries cheap SAE & Metric tap/die sets. Around $20. Use a real good thread chaser for plugs, not a cheap one. I also welded a 3/8in extension to my thread chaser. Snap On & Sears carries the longer spark plug sockets for this application. If you run across a plug that was replaced by a NAPA plug kit, plug/insert, one piece, they are 17mm!

 

I just did my plugs and cops on my 2003 F-150 and used the same 1/4" drive 7 mm and ratchet on all but #7...I had to use a 7mm box wrench to loosen and remove that one...And I did have a swivel spark plug socket with a hole in one end for the extension...Even with the rubber insert I never had the extension not pull the socket off of the new installed plug...

Changed fuel filter, plugs and cops in just under 3 hours... Then had a beer to celebrate!!!
