Questionnaire: How long are your Brisk 2MOR10S lasting?

[AldermanToffee]

From my understanding there’s quite a few people running the Brisk 2MOR10S plug now, especially those that are Stage 3 on 034 / IE tunes.

From a group chat with some others it seems like they are not lasting long.. at all. We’re talking around 2500 miles or so, tops.

I’ve personally just replaced a set after 2700 miles. After removing them I checked the gaps and all six ranged from 0.022” to 0.026” at worst - even though I had only re-gapped them around 700 miles ago.

I know of another person that had gone through two sets at a similar interval, along with a third person who went through a set even quicker.

To add to injury two of the plugs were loose despite following torque recommendations. Last time I changed the Brisk all six were loose. This seems to be a “common” issue across a few different engines with Brisk. I don’t want to over-tighten to risk damaging them.

[AldermanToffee]

Also to mention, these are the same heat range as the OEM NGK plugs despite some people thinking otherwise.

I had terrible luck with brisk on my c7 a6. Twice I had one fail at the track with maybe 500 miles on. Ever since I've run ngkbkr9eix but that's on the 3.0 supercharged engine

It’s odd. Brisk have pretty glowing reviews on the 4.0TT and seem to be recommended over NGK.

I’m not sure why they’re dying so early for people on this platform in particular. I’ve got a different set of Brisk that are a step colder on the way that I’m going to try out, but if not I’ll be going back to NGK.

If the Brisks aren't a step colder, what's the reason for not going with OEM plugs? I've always had better luck with OEM than any aftermarket plug.

A lot of people originally thought they were a step colder, mainly. We looked into it a few weeks ago and realised they are in fact not a step colder.

Other than that being silver rather than iridium provides a better spark in theory but at the cost of plug life.

what's the reason for not going with OEM plugs?

We looked into it a few weeks ago and realised they are in fact not a step colder.

To add some more context; When AldermanToffee and I were digging into this we found a variety of german car parts vendors that had conflicting information. All these sites were saying the 2MOR10S were comparitvely colder, hotter, same, etc... Depending on which website you were shopping you probably got a different interpretation of the heat range. I don't think this was a unique mistake to any one vendor. Plus the OEM plugs take a little digging to match up to the NGK part number (NGK makes the OEM plugs). So I can see how it's easy to get confused on the heat range.

Here is what we found:

Audi OEM Part Number: 06M905606F
NGK ODM Part Number: SILKGR9A7ES

NGK makes both plugs, you can cross reference both numbers, it's the same plug. They're a heat range 9.

Brisk Part Number: 2MOR10S

This is a heat range of 10.

Brisk has a chart comparing the two here: https://briskracing.com/pages/heat-r...eference-table

As you can see Brisk claims their range of 10 is the same as NGK 9. So the temperature should be roughly the same.

EDIT: I have not personally used the Brisk plugs yet on my S4, but just from experience on other platforms I've always been an NGK man. I'm tempted to either get a colder NGK plug or gap down the stock NGK plugs instead of installing the Brisks. I've typically had nothing but issues with other plug manufacturers on other car projects, feels like there is a reason NGK pretty much owns the spark plug market. I can't even think of a car I've bought that didn't have NGK as the ODM (original design manufacturer) for the OEM plug. Most OEMs just white label NGK.

Appreciate you posting that info.

There is a compatible NGK plug that is a step colder which I would be open to testing again. I did try this a long time ago on an SRM GTX3582R but it was misfire central when at moderate load and above. It might work better for my particular use case but I’m not sure it would be very helpful for the current hybrid turbo tunes - ethanol being popular now and burning cooler of course.

Yea I recall you saying :-/, maybe just re-gap the stocks then when I install my hybrid since I will be on e85. I think the silver substrate can make a performance difference for ethanol, etc... just sucks to swap them out every few thousand miles. Takes you back to the fouled copper plug days.

I'll stop derailing the thread though, I am curious how the Brisks are performing, would be great to get some numbers from everyone here.

[flee]

Brisk wouldn’t work for me no matter the gap. They would miss anything over e45 which is when I gave up.
That was on epl and 034 e tunes. Now on IE but will keep my oem’s until NGK offers a colder one.

[Paintedblack]

2MOR10S worked fine for me until about 2500 miles on the 034 stage 3 e60 file, then I started getting random misfires pretty much on all cylinders under WOT above 6k rpm. I just replaced them with stock NGKs and its running smoothly again. We'll see how long these last.

[FromS60toB61.8t]

Has anyone tried the NGK Ruthenium HX plugs on their B9 yet?
I ran them on my built B6 2.1stroker after blowing out the iridium's a few times and they were phenomenal. They were all accurately pre-gapped at .031" as well.
The ones I ran were SKU #FR7BHX-S, ITEM #NGK92400

Edit: after a short search, I don't believe they make rutheniums for our cars yet, atleast not anything past heat range 7.

Thanks for the information!! That all makes sense. Guess I'll be sticking with OEM plugs, as I planned.

Likewise two sets of Brisk failed on my S4 B8 with less than 100km on the plugs. Had 3 crap out in one hit on the second set. Went back to BKR8EIX and it was fine

[AldermanToffee]

R2558E-10 is an option that people have tried before but usually resulted in misfires at partial throttle. They’re also ridiculously expensive. I’ve got a set sitting around somewhere.

[Jose_Escobedo]

Stage 3 tte 710 guys using stock plugs, what are you gapped to? My brisks lasted me about 2500 miles and commenced the misfires. I put the oem ones back but at .028. Should I gap them to what the brisks were or leave them alone at .028?

I would recommend gapping to around 0.022”.
0.028” will likely be too high to be honest.

Ok I’ll pull them back out and make the gap less.
Thanks I appreciate it
