Glad to hear it. Also makes me feel better about installing the Champions soon. What did you use to clean the MAF?

 

I got MAF cleaner at pepboys. If you can't find it, you can get electronics cleaner and it works the same I think. Lots of people use either one. It's kept on the shelf near the carb/brake/etc cleaners at the parts store

I usually have this issue every time I reoil the filter

 

how much for a new filter? I don't want to have the same issues and I don't drive my car around that much so it would be worth it for me.

 

jlt filter is 50

 

You can also look into the Amsoil filter, check the link in my signature. It is a dry filter, no oil, and you can clean it with a vacuum or shop air. I have it and like it a lot. Just another option for you.

 

would need a retune?

 

Amsoil filter would not need a retune. I asked Amsoil about this and they said that as far as airflow was concerned, it was very similar to the stock JLT filter made by S&B.

 

Not sure if anyone has asked yet, but has anyone tried Seafoam first? That stuff worked really well for removing carbon buildup in my rangers 4.0l. When I pulled the plugs they looked like they just came out of the box.

 

Hey guys, I just want to throw it out there that Summit is now charging $15.99 a plug. Still cheaper than other places, but certainly not cheap like the first people who found the deal!

Darn.

 

good now i don't feel so awful for spending 17

 

For your information guys

I just spoke with Superchips Technican, so guys which supply my tune and they suggest to re-gap the Champion spark plugs to 0,054 like Motorcraft standard gap as this is what the tune and the engine was designed for.
On lower gap they expect some problems like i.e. irregular /uneven engine work on low rev.

I think I will re-gap them to 0,054 immidiately when I got them.
What you think?

 

I thought the motorcraft standard gap is .045? where did .054 come from?

 

.054 came from Ford, I think thats been the factory gap since the 4.6 came out in the '96's.

 

Go MotorCraft website part catalogue

chose Mustang GT 4,6 chose spark plugs and you will get a spark plug with 0,054 gap

BTW AUTOLITE Part # HT1 is also 0,045

 

I been running the Champions for a couple weeks at the .045 gap and my take is that the car starts faster and runs as well, if not a bit better than with the stock plugs
I pulled out at 11,000. Low rev/high rev, cold engine/hot engine, these plugs are working smoothly.

Now I have no idea if this will hold up long term over 1,000's of miles, but the plugs are working satisfactorily right now.
I sure don't see any reason to change the gap, it meets the specified range in the owner's manual (which I found the stock plugs
sure don't with .054 being about what I found).

 

hmm you are right Manual page 224 Spark Plug Gap 0,040-0,050

Here is a link to the new Ford TSB 08-7-6 (April 1, 2008) and pic of broken plugs.

It should how to remove the porcelain by gluing a rod in place of the electrode. This is going to increase the plug replacement bill. ...

 

One probably should follow the recommended gap by Ford.

I believe the gap has a strong influence on the discharge energy produced by the coil. I believe it takes more energy to jump a bigger gap. This does not mean that more than specified gap is better, but less than may result in less spark energy.

I am glad I stumbled on this thread. Pretty incredible the design got this far considering all the prototype testing Ford must have done before putting this into production.

I wonder how much influence the gasoline we use has on this problem with the carbon buildup.

It sounds like it is prudent to follow the TSB spark plug removal procedure, no matter the miles on the engine. Who would have thought you would have to go to such extremes though for such a simple procedure?

 

Wow, finally a TSB pertaining to the Mustang on the spark plug issue.
