Hey all,

Just got all 8 of my spark plugs on my 04 fx4 out wihtout any breaking!! The job took about an hour and half and a few bloody knucles..

Here is how i did it with an IMPACT...

- You can use a standard 9/16 deep socket for the plugs. What i did was just take the rubber piece out of an extra 5/8 plug socket i had and cut a slot out of it and it slipped right into the 9/16 socket and worked like a charm.


1) let car sit after driving for about 1/2 hour so it was just warm to the touch.

2) While cooling down, i removed the PCM and the bracket, as well as air dusted the whole engine and all the spark plug holes out.

3) Used 7mm to remove each coil boot and lined up to the side.

4) With engine warm i got my 1/2 inch impact and put it on the lowest setting as well as turned my compressor down to about 60psi and just went at each plug.. Once you push the trigger hold it until the spark plug comes out!!

5) for the back two plugs i used an extension and then a swivel and did the same thing as the front six, but i just made sure to hold the extension and socket straight so that i didnt break the plug or kill the threads.

6) Smiled and sat back for a second knowing that i got all 8 out without any breaking..

7) I used Motorcraft SP515 plugs. I made sure to put anti-seize on the end cap(NOT on the threads) and then installed them each and put it all back together...


So nice to finally be done with it!!

Good job. How many miles on the truck?

 

Jay,

It had about 80,000 or so... I didnt use any type of PB blaster or anything, just an impact..

 

Nice!! My buddy is a mechanic and I will be having him do mine shortly. I have a 06 f150 xlt 5.4 v6 and was wondering which motorcraft plugs to use? I will prob be getting them from rockauto as I hear there the cheapest!

 

There is no 5.4 V6, did you mean V8?

 

Mikey,

I believe as Jay said you meant 5.4 V8?!?! I use the Motorcraft SP515 plugs.. I got them at Orielly auto parts for 7.99 a piece.. I know rockauto has them but whenever i looked they would only have like 1 left or so, plus i didnt have to pay shipping..

 

Good for you. Did mine about 2 months ago. Any difference? I noticed quite a change after.

 

Good to hear and no doubt, a wonderful feeling when all 8 were out!

 

lol Yep I meant v8! I just checked out orielly and there are 2 diff engine models coming up for my 06 xlt. One is 5.4 v8 vin 5 330ci and the other 5.4 v8 vin v 330ci. How do I know which one is mine?

 

I believe that vin 5 is the gas and the vin v is the flex-fuel model.

 

Good to hear! Did you have the Lisle tool just in case? Or did you just go ***** out, yelling "Say hello to my little friend" with the impact gun in hand?

 

Look at the 8th character in your VIN.............

Correct.

 

BAHAHAHAHA I bought the Lisle tool from Rockauto just incase. didnt use it so i just returned it..

 

I just checked my vin and the 8th character is a W that's from the front of the vin.

 

W is a 4.6, not a 5.4.
