- Another fun time snowmobiling video with Adam Furlong from BYR Back Yard Recreation in Ayr Ontario. No Spark Plug Indexing Tool Required ;-)
In this video Adam, a licensed Ski-Doo Mechanic talks about e-tec Spark Plugs, where to buy Spark plugs for your skidoo, who makes the best spark plugs and more. Adam also lets us know the real truth for whether you should index your spark plugs on your skidoo etech engines and how to properly indexing the plugs. This tip is essential for all BRP Ski-Doo snowmobile e-tec Rev XP, Rev XS, Rev Gen4 engines with a 600 etec, 650 etec, 800 e-tec, or 850 e-tec engine - in the following model years - 2009, 2010, 2011, 2012, 2013, 2014, 2015, 2016, 2017, 2018, 2019, 2020, 2021, 2022, 2023

We love hearing from you guys - leave a comment below - Auta a dopravní prostředky
Nice video! Thanks for helping us out. I’ll be changing mine this upcoming week.
🌟
That’s really good to know!
Jason Campeau yeah, I was surprised to hear that
Always go right to the source for reliable information!
you betcha! Adam is AMAZING!
This guy is not the source. BRP is the source. I'm sure hes a decent small engine guy. And I'm sure his experience has taught him a trick or two. But his information is false on everything he has to say after the intervals topic.(read my comments above) Just remember hes a man with an opinion. It doesn't make him right. I've been in this industry for probably as long or longer than he has. It doesn't make me right either......I'm just pointing out a blatant untruth to the dealer only spark plug portion of this video.
Great information..👍🏼👍🏼
adam is a smart cookie! I learn something every time i talk to him
Good stuff . I'll be taking my Blizzard there for service.
absolutely! not too far for you at all from Burlington
I know that the brp plugs don’t index the same . I had run into this and one indexed at 12:00 and the other one at 6:00 . If you take a plug that indexed properly and look at where the threads start on the plug and find one the same it will index properly, or you can do as some people have posted and bye a pay check worth of plugs.
The BRP index zone is a 270degree area facing the injector, so your 12 and 6 are 180 degrees from each other. Considering thats less than 270, you are likel AOK
I bought plugs at the Dealer Performance NC in Valcourt Quebec where i’m from and where ski doo is made
Well for my 600ace 2011 so it’s from the real dealer so , as told in the video I shouldn’t look at the gap it’s supposed to be good ?
It was cheap 7$ each at the dealer
Good video, I was stuck on the ice in the middle of Georgian Bay 1/2 km from my cottage because dealer failed to index the plugs properly on my PDI......
noooooooo
@@mudbrats yup…. I’ll respectfully not mention the dealer… honest mistake, they owned it, fixed it and all good
Your engine shut off because of the plug index? I call bullshit.
@@DonziGT230 I'm afraid you are wrong, it's well known that eTec sled engines will not run properly if the plug is not indexed.
@@robandrews4925 Yes, I didn't realize this was specifically about that engine.
How do you know what torque should be or is that what the washer does for you?
Ski-doo manual says 20lb ft but good luck getting a torque wrench in there so half an Ugga Dugga just so the washer is set. Keep in mind, the index area is a 270 degree zone facing the injector.
So is there a proper FP of torque for the plug to index properly?
skidoo says all plugs 20ft lb but you are not going to get a torque wrench in an etec - no room. If you still believe indexing is important, know that the window of success is a 270degree area to be properly indexed - the opening will never be exact to the intake and youll likely strip a plug if you try. If its in a 270degree zone of it, youre fine
Can you take the crush washer off the BRP plug be replaced and put it on the cheaper plug and get the indexing to work when tourqued?
i wouldnt as that crush washer is likely flattened out
No, the washer is calibrated to each plug. If you move it to a different plug, the whole idea of having the ground electrode clocked just right in the combustion chamber is out the window.
And you should explain why they have to be indexed
Do you have to index plugs on an 05 ski doo 600 sdi ?
The same theory applies as in this video
So what’s the correct torque value?
oem says 21ftlbs but just enough to seat that washer
For the plugs to always index properly right out of the box, the threads in the heads and threads on the plugs would all have to be nearly identical; this seems extremely unlikely. Have you marked and checked the index on these plugs after installing to verify your theory? Also, which direction should the opening of the ground strap face?
Opening to intake.....The index zone is 270º area so to "Properly index" its a pretty wide area not many people realize, so your theory on exacting threads isnt important - the crush washer is.
@@mudbrats You clearly don't get it. No matter which crush washer you use, the threads will determine where the spark plug lands. I got curious after seeing this and did a little digging, MANY people report their dealer purchased plugs not lining up when torqued.
So are those dealer plugs in the video. The new ones?
Yes - all the way
So you are saying that the PZFR6F (7550) that I have in my hands on my non dealer shelf ......in the exact same box and have installed and sold piles of......originate from a different source than where a dealer gets them from? WRONG!!!!....ill tell you that right now. If that was the case NGK would make 2 different part #'s for your plug and mine........Legally they would have to. I've been doing this parts and service game for a long time. I dont know which dealer is spiffing him for making such false claims but I'm here to tell the public that its BS. As long as you are using that
PZFR6F(1550 old)(6876 new) in the 1st gen 600
PFR7AB(1583) in the 800
ILKR8Q7(93819)in the 850 and new 600
(May be exceptions to the rules above so double check before installing)
And indexing according to the manufacturers instructions you will be set.
@@alanritchie9620 This is a licensed BRP technician and a damn good one at that - he is not a dealer and has no reason to steer us in the wrong direction so belive what you want - I am buying mine from my dealer and you can buy yours where you want.
@Alan Ritchie Dealer code for an 850 or 600etec for example is an NGK ILKR8Q so you using the PZF is in the totally wrong ballpark, sorry man
Just got two plugs from my local dealer… and they did not index correctly
Same here
Yea, I find this guy's theory to be BS. For it to work as he says, the threads on the heads and plugs would have to all be cut nearly identically, and if they were, the crush washer hardness would make nearly no difference.
@@DonziGT230its the washers thickness that makes the difference
I have bought plugs from the dealer that had to be thrown away because they wouldn't index to the right position.
do you realize the zone of index is 270degrees - they dont have to be exact lined up
@@mudbrats yes I do,, I have had E-tecs since 2009 when they first came out, so i am well accustom to them, and this plug was really off!!
I'm going to have to call BS on that one. I'm completely familiar with indexing and the reason why that is a good thing to do for the best performance but unless the spark plug hole, of every single engine, the hole is tapped clocking the tap exactly the same way there is no way a BRP spark plug can be clocked (indexed) correctly every time. Can't happen!
If you are so familiar then you know the zone is 270 degree area within the gap for proper index spec. It ok to be wrong, we will still love you
I found that they weren't very tight when they were close to proper orientation (marked with marker open side) had to keep going till tight as they'd go! Frustrating.
the zone is actually 270 degrees within the open end to be properly indexed. Doesnt have to exact match up
how can you guarantee proper indexing by using that plug? the manufacturing process on the heads alone would require exceptional levels of detail to exactly tapping the spark plug threads let alone matching that to the manufacturing of the spark plug itself, and manufacturers aren't in the business of creating perfect clean room required built engines for most commercial uses. I'd be interested to see you get a few random cylinder head and torque them to spec and see how they index. no hate, just I just don't believe it at this point in time
Do you realize the zone for a properly indexed plug is a 270 degree area to the intake port? It’s not an exact science by any means.
That's why there 25 bucks a piece
You forgot to mention you gotta use a torque wrench
good luck getting a torque wrench in rhere
@@mudbrats actualy impossible I swear
Sorry, but disagree on dealer plugs will screw right in and be indexed! When motors came out needing indexed plugs it didn’t matter where we got them, MOST of the time we had to index. Also, if dealer plugs were already indexed, how come many times we would try a ‘dealer’ plug in one hole but not work in another. And we were a dealer! And for more info, DO NOT PUT EXTRA WASHERS on them to make them index, try a different plug. You put in a sparky with just the fingers until the washer touches, if it’s exactly opposite, or 180 degrees from where it has to be that one will work when tightened. I/we have already gone through a dozen plugs for a Evinrude Etec V-6 motor just to get plugs that work. Sometimes got lucky and six plugs for 6 cylinder motor, but that was rare.
Adam is a licensed BRP tech and has a decade of experience at a busy ski-doo dealer. He knows what he is talking about
@@mudbrats sorry don’t sound like it!
Plugs shouldn’t be arcing in the boots! If they are, replace your spark plug wires.
Arcing only occurs with loose connections. A spark plug connection is designed to have zero gaps between the plug and connector. Electricity can not arc unless there is space.
Dyno your indexed plugs vs non indexed. Guaranteed there’s zero improvement with indexing.
great tips
It not necessarily performing better, it’s the fuel injector spraying/cleaning the plug so they run longer hence better in the long run.
Yup. And replacing $25 plugs just because the replaceable cap is burnt is dumb.
I bought dealer plugs and they did not index right. Just saying. If your going to replace them Index them probably. You want the gap to face the injectors.
You’re not gonna get it perfectly lined up unless you use spacers. oem specs a 270 degree area For properly index plugs so it’s pretty tough to screw it up unless you have the back of the electrode Facing at the injectors
Show us..prove it.
Well though out thanks.
Trust me.
Thanks!
No offence but that's complete BS ...second time I purchase a set of plugs from BRP dealer here in Sudbury and have plugs that are 180 deg out of index even after playing musical plugs as well as max secondary torque . Just found out about plug shims(30deg) per shim. Thanks, but get the facts straight...hope others can benefit from this info. 90 hp ETEC = 2yrs max on a set of plugs as iridium tip gets eaten and gaps opens to .050". Cheers !
you do realize the index zone is 270 degrees... doesnt have to be exact to the gap. I think a lot of people think it has to be precisely lined up. The 45 degree on either side of the back of the electrode (90 degree area) is the no go zone. So you were in index area if you were within 180 of the opening. Dont call BS on this video when you dont have the facts straight
Sudbury lol. Dont go to BRP here. Go to Sturgeon Falls
Why index the plugs
it places the spark plug gap toward the intake for a better ignition of the fuel. Theres a 270 degree area for best performance. as long as the back of the electrode doesnt face the intake/injectors
You don't throw the plug out!! You spend $6 for indexing washers
Bingo. Great tip!
Sorry bud I call bullshit a spark plug doesn't index it's self. And it doesn't matter where you buy it from they all come from a manufacturer like ngk then go to all the other places just bc u pay more for the same shit lol
👍
Agree, total bullshit.
