spark plug gap

yeah, i just took the autolites back cause i dont think they are even close to the ngk's after some further research. also having trouble finding the ngk at the local stores???????????/
 
I had trouble too as these plugs apparently aren't stock issue on any cars. I read somewhere that one of the plug types were stock for a motorcycle?
Anyways, read the NGK extended Reach Plug thread in the FI section posted by Linux Racer. All the part #'s are there.
For example, the BKR7E's are NGK part #6097.
 
Just order them from sparkplugs.com. They even send you a nice little sticker :).

hey MS MSP, if you want a JoeP FPR, I'll give you mine. It's never been installed ( i chickened out) and I have full instructions on installation.

Rawyzf, does that website ship to Canada?
 
Im in MN, so I'm not sure. I am as close to Canada as it gets :).

They do however have a phone number for customers outside the US, so I would guess that they ship to the frozen tundra.

This is from sparkplugs.com:

Turbos and Blowers

Whether using a supercharger or a turbocharger, both have the effect of increasing the mass airflow into the engine which increases engine displacement. With the additional displacement comes not only an increase in horsepower, but also an increase in firing tip temperature, thus requiring a colder heat range spark plug. If however, you have added extreme boost or a combination of boost and other modifications, changing heat ranges may not be enough. Tip configuration may also need to be altered, as there are a variety of firing tip choices, it would be wise to consult your engine builder or performance tuner specialist for input.

I think they do ship to Canada, and thanks MazdaDryver, I have a FPR already waiting to be installed.
If you still want to "give it to me" though, i'll pay the shipping !

You can get the plugs from anywhere as long as you have the NGK part #. Even the monkeys at Canadian Tire found the 6097's for me. It took a while, but they found them.

So far I'm very pleased with my new NGK's - I had the BK... but since changed to the
ZFR7F-11, part #2975, .30 gap (I had to pull out my notes for exact name and part number - don't keep up with that crap) - I'm also at 10+ psi w/other 'stuff' ;) so I'm not exactly stock.

Anyway, the new extended reach ones make the car definitely feel smoother than the BK's - thanks Discreet, Linux and everyone else offering input regarding this - (2thumbs)
 
Well I checked that website, the cost of the plugs with shipping was rediculous. Canadian tire cant help me here either. I called Partsource in Ottawa and they are going to try and track it for me.

MS - pm your addy and I'll send you the FPR. Dont worry about the shipping cost,it couldnt be more than a couple bucks and I'm just glad you can use it.

I also have these plugs which are the same size and 2 heat ranges colder from our stock plugs. I have them gapped at .030, and they run smoother than the BRK7E which everyone was recommending when I first joined the forums. Any auto parts store will be able to get them under the NGK PN 2975, and they are only a few bucks a piece. It seems like a no-brainer to me that these would be the correct plugs to run at higher boost considering the only difference from the stock plugs is heat range (copper).

On sparkplugs.com it says the gap is 14MM for the ZFR7F-11 plugs. What does the equal? .030?

Actually, or stock plugs are ZFR6F, so your new ones are 1 heat range colder, not 2.
 
Not to keep the wagon going in circles, but don't you want to buy plugs that are already gapped right, or the center spark or whatever can be off?

Supposedly there are Denso's that have the same specs as the ZFRF's that come with the proper gap for our cars.

Yes. I have the Denso equivalent. I have the KJ22CR-L8 which are the equivalent to the ZFR7F-11. They are pregapped to .8mm which is about .032" I believe. I got them at www.sparkplugs.com. Paid a little more since I had to pay for shipping but, oh well.

Can you run colder plugs at stock boost ?
Will they perform as well as the stock one ?
Also, I heard that they would wear faster... True ?
 
Copper plugs will wear faster than the stock platinum's., but copper is better for F/I.
It depends which plugs you run.
So, you will have to change the coppers more often, but they are cheaper than the platinums.

Yep... I just put mine on yesterday. Car definately feels smoother... now on to the mbc @ 10psi! Probably do that today.

What about irridium ones !? Will they be OK (stock and higher boost) and last longer ?
