3.5 L sparkplugs

[RJC109]

HI

I know it seem early to think about spark plugs, but I was wondering about putting in better that oem. I believe that you have to take off the intake manifold to get to the rear plugs. Has anyone replaced the plugs and might know of an 'easy' way? I have 30,000 on my 2008 Edge Limited and no problems. I think the chrome plastic wheels on the limited cheap. I will add new wheels when the tires wear out.

If there were better ones than the OEM plugs don't you think Ford would have used them? Just use the OEM replacements. I wouldn't worry about them until at least 75K. Technically you can wait until 100K but you don't want them to seize up.

Sorry for just now seeing this thread. You have to remove the intake manifold for the RH side plugs, yes.

 

 

LH side

 

1. Disconnect the crankcase vent tube quick connect coupling from the valve cover fitting and position aside.

 

 

RH side

 

NOTE: The upper intake manifold must be removed to access the RH spark plugs only.

 

2. Remove the upper intake manifold. For additional information, refer to Section 303-01.

 

 

Both sides

 

1. Disconnect the 6 ignition coil-on-plug electrical connectors.

NOTE: When removing the ignition coil-on-plugs, a slight twisting motion will break the seal and ease removal.

 

2. Remove the 6 bolts and the 6 ignition coil-on-plugs.

NOTICE: Only use hand tools when removing or installing the spark plugs or damage can occur to the cylinder head or spark plug.

 

NOTE: Use compressed air to remove any foreign material in the spark plug well before removing the spark plugs.

 

3. Remove the 6 spark plugs.

Might want to rethink the 75k miles replacement time line!

 

The manufacturer is not always right to say the least, lets look at lots of manufacturers and their supposed 90k spark plugs (BS), or lifetime transmission fluid because the transmission is " SEALED, " um no, that does not work either. Don't trust me, well wait till you have to replace and AUDI, BMW, Jaguar, or other manufacturer transmission with LIFETIME fluid, or have a blown engine due to spark plug failure WAY before the 90k suggested replacement.

 

Just replacing my spark plugs now at 40,850 MILES and glad I am to be doing so as they are at .57 for gap (out of the allowable .52-.56 rage) and the tips are very worn, and the electrode CRISPY from running hot! I highly recommend every Edge owner to replace your plugs ASAP if you are anywhere near even supposed HALF life for these platinum plugs.

 

After all things wear out, just like you or I will someday if we don't take care of ourselves, so why not take care of our cars like we should be taking care of ourselves too.

 

- BTW I am sticking with Motorcraft plugs, just because it is a good design for a plug and is truly a fine wire platinum. Normally I am a NGK, or Champion Double Platinum FANboy, used to be a BOSCH fan boy for all my EUROs back in the day, but they suck supremely now in EVERYTHING.

In shade tree mechanic terms would RH stand for the front or back side of the motor?

And will there be any gaskets to replace?

I ask because at 53K miles this is working it’s way up my todo list.

 

Thanks
