I just received my order of plugs from Coffey Distributing, and they sent me BR9EYA instead of the BR9ES that I ordered.
My question is , will I blow anything up? are they safe to run in place of the BR9ES ,? In all applications?
I called them about it right away and All that I know is that they told me it is a better plug as well as a antifouling plug, and they said it is ok to use them. ???

i think that br9eya is only a cat plug it to hot for polaris not sure about doo's

They are the exact same heat, and are a far superior plug at preventing fouling IMO.

the eya is a anti-foul plug and for any brand

Yep, that's what I run in my Skidoo.

If I'm not mistaken the R means resister, the 9 is how hot it runs and the EYA is anti-fouling. Therefore, they're both 9's, they'd both be the same temp.

I haven't noticed an improvement w/ the EYAs, so I'm back to the ESs. I don't recall what the price difference is.

BTW, it figures that Coffey's would send you the wrong parts :D :angry:

I buy my BR9EYA's at Farm and Fleet for $1.60, and they have the solid top, not the screw on ones.

The EYA's will not cure a fouling problem but are know to cut down on it.
Just like back in the late 60's early 70's when Champion brought out the anti fouling plugs for oil burning Fords, helped em to run longer before fouling but of course didn't make em burn any less oil............they needed a miracle for that. LOL

:nervous: thanks guys, I guess I'll run them instead of shipping them back, the season could be over before I got the others...
Thanks again Rodney.. :sly:

They are supposed to be an antifouling plug like stated above. However there was an article in a sled mag last year, saying that even though they are both rated as the same heat range, the eya's actually run a little hotter.
I don't think you will have a problem. They are more of a cat plug, but shouldn't be an issue. However I'm surprised you can't fine BR9ES, they are sold everywhere in Ont.

Canadian Tire, Walmart, Home Hardware to name a few.

You might want to check NGK's website, they also have some good info.

I've heard the same thing there FishHog but since its rated the same don't understand how it could be, maybe I'm missing something. I have however substituted them for some time now in different make sleds with no issue.

Isn't the only differance between the two that the EYA is a v-groove plug and the ES isn't?

go to the home page of this site and there is a explantion of the numbers on the sparkplug/
here is a link, hope this answers your questions.

Yes, V groove on the center electrode.

The v-groove on the electrode is not the only difference between the two plugs. If you hold them side by side, you will notice that the electrode sticks out about 2 mm higher on the eya plug. If clearence is very close on some machines this could be a problem.

What is the difference with the br9ecs? That is what my summit takes.

The reason they state that they are non fouling or will help with the problem is because of the solid tip. When a standard screw on tip is used it can get loose and cause fouling. With the solid tip this will not happen.

Fishhog, it isn't that I can't get the BR9ES, it is that they are selling for 4.49 plus tax .around here and if i get them from Coffey they end up at around 2.50 each tax incl.
Anyway, I am going to try the BR9EYA in my STX and if the guys that I ordered for dont want theirs, I'll just send them back... ???

$4.50 each is a little steep.
I don't think you will have any problems, but from what I have read, they burn about a half a step hotter than the es.
If you do a search on this site, you can find some of the old threads which discuss this topic.

I tried to find the original article, but no luck. I think it was in SnowTech, about a year ago.

This is right off of this site:

i wouldn't use them ....if you melt down i dont wanna say told ya so :(

since iam the only one saying not to use them CALL your dealer and ask

keep us posted!!!! iam courious :D

still running?

no update?

How come nobody #####es about being told to use NGK plugs?
Then you can start asking why you can't use $3.99 Champion plugs in your SDI.

I posed the following question in the 'doo section but haven't gotten a reply:

Does Champion or any of the other spark plug maufacturers make a equivalent plug for the BR9ECS? the plug has been around for awhile, so just curious.

To kind of answer my question, I checked what Champion recommended for the '99 SRX which used BR9ECS plugs.

Here is what I found: "Super Class" Powersport Plug #8902 (copper core w/ small center electrode) @ $6.29US

"Regular class" N2C or RN2C @ $2.24US

I am in no way recommending this plug, I was just checking to see what is out there.

For those of you who haven't seen the BR9ECS, this is what it looks like.

I gotta try some EYA's in my XLT. It likes to foul its plugs just to #### me off i think. :lol:
