Spark plug options

[Sy1100]

So who has changed there plugs, and what did you use? Just wondering cuz 6k on my sho will get here quick and I would like to see what people are using/like.

 

[zblackbeast]

just use the autolites .. the sho seems to looove those..

 

[93rev2sev]

zblack is not realizing this is the gen4 forum.


What's the spark plug interval, anyway? I would have thought 100k.

 

[zblackbeast]

nope.. I just woke up and just clicked on it. ha.. But, i would imagine its the same or motorcraft for an OE fit.. I saw the 6 and thought he missed the 0! ha Sorry for my momentary brain fart!

When did Ford specify ecoboost plug intervals at 6K?

 

[thebigjimsho]

At 6k? That is not the interval. If you think that will help, make sure to do turbo rebuild while you're at it...

 

[thebigjimsho]

Oh, and just use OEM. Spark plugs make no difference unless the quality of said plug is crap...

 

[SHO U UP]

Don't ya mean turbo(s)? :laugh_ti: I was beginning to think someone had racked up some major miles on a 2010 already.

12k and no plugs but my Suburban has 200k and still has the factory plugs in it.

Wow, the electrode has got to be a tiny little stub on those plugs.

 

[Sy1100]

I always change the oil at 3k and the plugs at 6k. I've owend to many turboed vehicles and come to the conclussion that changing the plugs every 6k is good isurance. I didn't ask what the interval was.

Please send me your used spark plugs. I'll put them in my car when its due.

I know but to set fire to a compressed gas air mixture the spark doesn't have to be that big does it?

The explosion is going to occur even if static electricty sets it off, throwing more spark at a bomb ends with the same results, it doesn't get more enhanced by the size of the match.

(my opinion)

What about top fuelers? They're running nitro and they got 2 magnetos. It's not if it will ignite or not, it's the efficiency of the burn. A hotter spark yields a better burn. Even at idle, each cylinder is firing 5 times a second. If you're turning 5K, you want an efficient burn. Anyways, I checked the maintenance schedule and the first I saw of spark plug replacement is 90K. That's under cars and CUVs and doesn't break out a turbo. I think replacing the plugs at 25K would be the earliest for someone **** in car maintenance. I say **** in a positive sense.

"Due to the relatively slow burn rate of nitromethane, very rich fuel mixtures are often not fully ignited"

Plus they only have like a 6.5 compression ratio

The stock plug is the CYFS12F, For another option I would suggest using the AYFS092FEC which is the plug from the SVT focus. might not be a great choice for light duty use in winter, because its a colder plug. but it also has a copper core sidewire and is also double platinum, both good things. it would need to be gapped down to the .035" gap to match the stock plug. use antiseize too, because its a black-oxide shell, not nickel plated like stock.

also I would suggest buying a few sets of the AYFS092FEC now, because they are out of production...

You sure didn't.


I did though. Still waiting for an answer, too.

Your car, you can do what you want - 6k mile plug changes are completely unnecessary with modern Iridium plugs though. I changed my SC'ed Grand Prix's Iridium plugs at 75k miles (25k before recommended) and the spark plug gap had only widened .002 of an inch over those miles (supposed to be .060, was .062). The new plugs and wires made little to no difference in the way the car drove - I could have held out to the 100k mark easily. Older turbo cars like my turbo Talon *do* need plug changes every 10k miles or so because they use copper plugs - they wear out much faster.

After you send wchain your first set of plugs, can you send me the next? I want to **** them off on Ebay. Iridium plugs are $8 to $10 each......

i too dont see a reason for changing plugs in these newer cars till 70-100k
i did change the plugs in my 87 turbo regal at about 1000 miles but that was due to...
they were about a $1.00 a piece, i was running 110 leaded fuel and running about
26-28 psi of boost. the lead would coat the plugs and i didnt want to have any backfires
on the mean streets of detroit at 3 am.!!!
not sure if the turbo guys that ran the alky injection needed to change plugs but i have not seen anyone mention those kits on these cars. (im a newbie here)
