I changed my spark plugs for the first time today and it could not have gone smoother. My neighbor (who is a mechanic) came over and set up a carbon drip that plugs into a vacuum line. It dripped about 20 minutes. It breaks up the carbon that builds up around the electrode. Once the drip is completed you pull the coils and the plugs. The plugs didn't even squeak upon removal, they came out as easily as the new ones went in. You pull them with the engine still hot. If you can set up this drip I think it will decrease your chances of breaking a plug.

I have also only ran 91 octane Chervon gas in my car since the install of my CAI, which might have helped with controling the carbon build up on the plugs.

My car runs so smooth right now, it feels kind of strange!

 

Sounds good ,I'm thinking of doing the E3's next time ,,did you go back stock ones or up grade to a different spark plug ,,I also only burn 91-93 octane because of my tune for the last 4 years now ,,but car only has 22500 miles on it today and its a 2007 .

 

I went with the original equipment plug.

 

man I have to do this soon 65k here

 

Agreed, I am scared, very scared to do this in my 07.

 

Sounds like the drip is the best yet.

You drips

 

I would very much, as a lot of others might, be interested in how this was done, with pics and the magic cocktail that was used. I completely understand the concept, but would love to see a diagram or such to ensure I don't screw up... And also get the right concoction.

If possible. I'll undertstand if not... I'll just... well... *shuffles off*

/Fantastic news though. Perks me right up about maybe gettin' mine done now.

 

I will get the set up from my neighbor and re-enact the process with some pics and the fluid that was used to deal with the carbon. I Should have done it in the first place. Check back tomorrow.

 

many have posted that theirs came out with out problems. So I.m not to worried about it.

 

Pic 1 Is the kit that I used. Granitize De-Carb Part# AD44, Granitize Tune-up which is fuel treatment, and Granitize Air Intake System Cleaner which is the throttle body cleaner.

Pic 2-3 is the delivery system.

Pic 4 connects to the vacuum hose.

Pic 5 shows the hose that we connected to.

Pic 6 is where the drip is regulated.

Once the system is connected you run the car for about 20 minutes which should empty the bottle. Based on the miles on the car this should be repeated. 60,000 one bottle, 100,000 two bottles, over 150,000 three bottles.

Like I said, this process worked very well for me. However we were prepared for the worst if a plug broke. I hope this helps someone.

Here the link for the DE-Carb, but you can find a useable product at you local autoparts store. http://www.granitize.com/index.php?pageId=333

 

Kewlness. Thanks for the info!

/gonna happen soon on mine.
//81K... probably needs to be sooner than later now...

 

So does the drip consist of the decarb and tuneup bottles combined?


Also I've read that you're supposed to remove the plugs cold not warm because the heads are aluminum. Although I've heard both cold and hot so which is it?

 

No, just the de-carb, the tune up bottle goes in the tank. I see the tune up bottle as just another fuel injector cleaner like Seafoam. (Seafoam is really good stuff though).

If you search the subject on this site you will find opinions and arguements for both side about hot and cold removal. My neighbor the auto tech said to remove them while the engine is still hot. I know removing them hot worked for me, so I lean to the hot side.
