NGK spark plugs

I have a 03 Ranger 3.0 with 35,000 miles. Would it be worth it to replace
original plugs with NGK. Seems I have heard some good thing about NGK.
Thanks.

I won't tell you the NGK plugs are no good. I have used
them for years in my motorcycles and imported cars. My
experience with 20 or so personally owned Fords over the
years has been that the OEM Motorcraft or the Autolite plugs
perform best. They are readily available and less expensive
than the NGK in most cases. If you go away from the
original spec plugs, you are experimenting on your own
nickel. Also, I didn't think the Ranger required a plug
change until 60K miles like the Taurus/Sable. The 3.0 in my
Sable developed a misfire at about 65K miles. Good as new
with a set of Motorcraft OEM spec platinums. Part of it's
problem was a stuck IAC which cleaned up nicely.

Re: NGK spark plugs

Thanks. Was wondering since at idle I can feel a roughness and took it to
the dealer who checked it out. Supposedly did a diaganostic on it and said
there were no problems that showed up and that the roughness was normal.
Called it a characteristic of the 3.0, something called powerback.

Re: NGK spark plugs

The 3.0 is normally smooth enough that it is not noticeable
idling. Ford IAC's tend to gum up and get sticky. This can
and usually does result in a bit of roughness at idle
because of it's inability to be correctly controlled by the
PCM. The fact that it did not show up as a problem at the
dealer is common as it rarely produces a fault code just
because it is in need of a good house cleaning. They
usually behave best when warm with the most noticeable
proble being a bit stubborn just after a cold start since
they cannot bring the cold idle speed up to where it should
be. It is easily cleaned with throttle body cleaner. The
best way to clean it is by removal so you can get at it's
internal area directly. IIRC, you will need an 8mm wrench
or socket to remove it. It is located on the side of the
throttle body. Your throttle body and MAF sensors also
probably need cleaning. An old tooth brush is a major help
with the throttle body. The MAF should be cleaned with a
non residue electrical cleaner to remove any oil
contamination. It should be located in the air tube between
the air cleaner and the throttle body. I would take care of
these items before screwing around with the spark plugs. It
may just take care of your problems and is probably due
anyways.

Re: NGK spark plugs

Funny one, there... My '02 Taurus developed a misfire. Turns out it was
the #2 'terminal' of the coil pack. I had already replaced the plugs,
wires, fuel filter, etc. I first put in Bosch Super Duper double platinums
(center electrode, 4 grounds) and the misfire still occurred. Some cars
aren't happy with Bosch plugs, so I put in the d-p Autolites. Still had the
problem. Next step was more than likely the coil pack, and since we already
had an appointment with the local Ford dealer, I took it in for them to
diagnose. I told them my story, and the service tech (older gent) asked if
I still had the plugs, and was interested in the #2. When I pulled them,
the #2 had a bit more gap than the other 5, but looked exactly like the
rest. Coil pack was changed, but the tech had some advice... Get rid of
the Autolites. They'll cause problems of their own. The plug wires? Not
worth having! Buy them from the Ford dealer!! Yeah, right! Car runs fine
with higher $$ plug wires from Auto Zone (lifetime warranty) and standard
Autolite d-p's.
