This is a very common problem on these cars, and you should have it looked at before something goes...BOOM...
If you search around these forums, you'll see that about 50% of the engine failures are due to the #3 piston losing it's upper ring land because it was running too lean.

Not trying to scare you, but if it were me I'd want to get that looked at.
FWIW, here's my observations on that same plug:
http://www.focusfanatics.com/forum/s...ad.php?t=86929
I made sure all the intake to head hose clamps were tight, ran a can of injector cleaner through it, and had the tune adjusted slightly.
Haven't seen a lean problem in that cylinder since then.
WOW, will be checking mine tonight.


Is there any gains with a COP set up on the SVT?

edit: I gapped it at 60.
This isnt from ware , there is a lean issue in #3 from what I am seeing but my guess is something entered the combustion chamber and broke the plug , the wire is bent closed (gap) much more then the others and the tip of the electrode is gone this does not happen from ware or heat with this type plug

Ok there are so many posts in this topic...

I know the Denso Iridium plugs are the best for the SVT but I still have 2 questions...
On Denso's site they list a gap of 0.40 for '04 and 0.50 for '03 on the SVT. So is that a misprint? And if so it is supposed to be 0.50?
What are the BEST wires for the money--or should I just spring the $$$ for the absolute best.

and post up answer's to the more commonly asked questions.

Do I need to upgrade my coil?

Simply put.... No
Stock coils will provide enough spark to support over 700whp. The average 4 tower coil will put out between 36-40k volts most aftermarket coils put out only 42k MAX. You will not see any gains what so ever by swapping out a working stock coil for an aftermarket one.

Do I need to go with those really expensive plugs?

Again.... No

Unless you have a HEAVILY Modded (MORE THAN BOLT ONS) engine there is no need to use any other plug than STOCK. You CAN re-gap the stock plugs to .060 (in most cases) and you will get a smoother idle and the overall running of the car will be improved... but just slightly. When you open up the gap it take MORE voltage to jump the gap and make spark.. therefore wider the gap the hotter the spark.

Now if you are running Nitrous of Forced Induction then yes you can benefit from changing plugs. I highly recommend the MotorCraft AZFS22C f4 sparkplugs. They are copper cored (which is one of the BEST conductors of electricity.. better than Iridium) and will provide a wider,stronger spark. They also work VERY well with NA engines,and at $8 a set you cant go wrong.

Should I change plug wires?

Yes

Changing your plugs wires is problely the most effective ignition upgrade you can do on a Focus. Any descent low resistance wire is MILES beyond the stock wires... I can not say how much I despise stock wires for there inability to carry good voltage. Remember the bigger the wire the better... smaller wires will heat up internally and heat greatly reduces their ability to conduct electricity.


Well thats your basic ignition questions covered... feel free to ask any questions that you have.

Now taking the first post into context.

I have seen a few COP set-ups on SVT's one using 300M coils and another using duratec focus coils.

What is the max out out for those coils, since the line of resistence is shorten due to the coil being on top of the plug?

Can someone tell me what would be the best plug for a SVT JRSC with BBk? I'm replacing my copper plugs, before i get the s/c installed.

I was looking at these from CFM, mr should i just get another Copper set?

Hey guys I've been checking out this thread (not all 30 pages) but my car has 92xxx miles on it and it seems to be idling a bit rough..especially when its warming up and I'm thinking of doing an entire overhaul so are there any reccomendations as to plugs, wires, or even coils. I only put about 5-7,000mi on it a years if that's a factor.

300m coils are good for around 40k (which is about the "norm" for most oem coils)

airFS in your case I would still recommend a wire upgrade (taylors, FordRacing or any other good wire) stay away from MSD wires.... unless they have changed lately their wires only work with the older design coil... or their coil.

As for plugs stock plats gapped at .060 should do great.
