I have 2 questions about cop(coil over plug):
1. Has any one used the Accel cop yet?
2. As, I can only find the ones to fit the 5.4L motor, Can the 5.4 cop be used on our 6.8L?

Thanks for your input.
Tommy

 

I can't tell you from my own experience, but what others have told me the Accels were a good replacement.

And yes, the COPs and boots are the same for each engine.

 

Granatelli Motorsports has replacements as well. I'm using them and haven't had any problems thus far.

Seems like a good product from the info they provide on the link. However, I would imagine that all 10 COP's need to be changed due to the increased spark output. So...and nice upgrade option.

Might have to remember this for the next question that comes in, "How to increase hp/torque on my V10" when asked.

I got a reply from Accel. They also said that the 5.4 cop would work, as long it's a SOHO V-10(6.8L).
Now I have some shopping to do. As, I have some lost mileage, and ruff idle, and the normal things go a long with having 100,000 miles on a 7 year old truck. The plugs were replaced at 65,000. I know that every one has their own ideas about when to replace the plugs, as well does Ford.....
Thanks for the input, and help in the future.

robottommy -- Do you happen to have the Accel Part #? Wanted to look them up...and see what the product claims.

Thanks,

biz4two- Yes at www.autopartswarehouse.com, under accel it's 140034. Listed around 25 bucks.

Just a warning on the COP upgades, and what they claim or MPG or power increases.

Someone, probably Fredvon4, already called BS on these claims.

Why?

Simple reason:

The emissions output of the V10 is SO clean that there is NO WAY any fuel is left over during normal combustion. This is for a completely stock engine in good condition. So, no benefit from a hotter spark on stock motors.

HOWEVER:

If you have a weak COP or two, $250 ($25/each) doesn't sound bad to do the complete set at once, and the hotter spark isn't going to HURT anything and can certainly improve cold-starts in very cold weather.

If the engine is getting marginal in terms of valve and ring sealing, the hotter spark can help cover up the wear.

Notice the MPH and power claims Granatelli has on that page are for a supercharged motor. Meaning, there will (should) be no improvement with a stock motor.

Not downing your choices, or Accel, just trying to bring some realism to the discussion.

 

That's why I went with them.

I am not looking for that magical increase of mileage or horse power. I just want it back to normal or at least some what close. The truck is 7 years old/100,000 miles, and in need of a tune up. And while I am in there changing the plugs and "wires", I wanted to see if there was a good lower cost cop. As, I have already changed one cop last year. The trucks check engine light isn't on, but it's not running the way I would like it, and I have lost 3 MPGs....
So, again I am looking to do a tune up. And this is what go me started asking questions in the first place.

Tom, no argument from me! In your case, the upgraded COPs might be a good way to go.

But before you do that, do all the things we always tell anyone who has had a dropoff in power or MPGs.

Clean the MAF, change the fuel filter, oil, oil filter. If the plugs weren't done yet, do them ... check the operation of the fuel regulator and check loaded and idle fuel pressure.

Even though it makes no sense you would use MORE gas if the fuel filter is clogged, regulator not working right, or marginal fuel pump, it does happen - we've had too many people report back that bad MPGs was a result of a fuel delivery problem (or dirty MAF).

Only then, should you change the COPs.

But that's just my opinion, and being a moderator doesn't make me more of an expert in anything than anyone else here

 

Appreciate the link provided!

15% more would be nice...if a person was going to change all 10 COPs, but still have to think stick OEM if only replacing 1 or 2.

I also agree with krewat about not really needing them for an all stock V10...but still nice to know they are available.

I AGREE!

Just kidding krewat...but the door was wide open for some kind of fun response...

Krewat,
We are all brothers in arms here.... So, there are no arguments... maybe a few disagreements... but, no arguments here. Plus, if some one can stop me from making a costly mistake … I will listen once maybe twice....
Now back to the issue at hand. It could be the “wires” that are giving me the trouble, but like I said, when I am in side there and it’s not to costly, then I will replace the whole she-bang…. As, I have been told it takes about 2-4 hours to change the plugs. And I am not sure, I didn’t do the last time, it was done at the dealers. If, I have to drag out all the tools and crawl up into the engine bay, then I don’t want to have to do it twice or figure out which one isn’t working correctly. With all of them replaced… then if there is trouble, then I can rule out the plugs, “wires” and cops.
