No. A few years ago when Brisk first came out with plugs for the N14 they had to be gapped. I think I got the first set from Alta at the time. And yes, I was not able to get them gapped correctly or there was some other problem with them. I kept getting misses under a heavy load like accelerating out of a corner.

Fast forward a couple years and now Brisk is producing them pre-gapped. Sneed's happens to carry them, probably because they run them in their own MINIs.

 

The only thing to remember with the Denso plugs is they use a standard 6 point socket instead of the 12 point used by NGK. I still had the socket from when i had my first gen mini so no problems. I gapped the Denso's at .027 and so far no ignition issues or pulled timing with the JB+ cranked up.

 

For $5 I found the 3/8" drive, 14mm deep well 12 point socket from Craftsman works just fine on the spark plugs. I used a beer keg line tube to remove the old and reseat the new plug. Could not see paying up to $50 for a special socket, it looks like I could have jammed the rubber bit from another similar spark plug socket in there, but the tube worked fine.

 

I installed a set of 5992's over the weekend in my 2012 CM All4S with 32k. I gapped them at .024. I do have a JB+ installed at 60% . The idle does seem smoother and my gas mileage seems to have gone up 10%. Both of these could be due to having 32k on the factory plugs... but for less than 1/2 the cost of the factory Beru's the NGK's are doing just fine.

 

Our magnetic socket is only $19...

 

I gapped them to .022 and I definitely notice a smoother idle, smoother acceleration, and I just reset my MPG monitor to see if that went up as well. Overall, the car feels much better just by regapping the plugs. I'm waiting on my local autoparts store to get a shipment of the Denso's and I'll be trying them out and then making a decision on which is best for me.

Thanks everyone for giving their input and I hope this thread will help out someone else.

 

What did you gap these plugs at when you installed them?

 

not trying to split hairs here, but i think both you and ragingMini meant to say 5992s, not 5922s. just wanted to clear that up for anyone else that might come across this thread looking for new plugs.

 

Thanks, I edited my post to correct that mistake.

 

Fat fingered that one.. you are correct 5992's....

 

Had the same problem


Didn't gap, just installed out of the box and she runs amazing!

*edit* these are the same plugs, as OEM E60 M5 V10

 

$23/plug ouchhhh. I still think I'm going to go for the Denso's first since they are colder than these and are half the price.

 

Anyone know why you aren't suppose to gap Iridium plugs?

 

You can absolutely gap Iridium plugs. I gapped my Denso's to .027. You just have to be very careful and close the gap a little at a time because what you can't do is put a screw driver or anything else between the electrodes to open the gap back up if you close it too far. Doing will destroy the center electrode.

 

Who uses a screwdriver to Gap a plug? gheez... the proper tool is under $10. In 45 yrs of driving I have never installed a set of plugs without properly checking and then gapping if necc. with the correct tool. I can only imagine if cars still used points and people had to set dwell what "tools" they would use....a BFH.

 

Believe it or not I used to see guys do it in the pits all the time on dinosaur motors back when I used to bracket race a 68 Firebird. Saw a lot of crazy stuff done or tried back then. What used to crack me up the most was when guys would bring in small blocks running nitrous without forged pistons. Usually never a happy ending... but sometimes the best lessons are the most expensive ones.

Kinda funny now that I think about as I used to have a tee-shirt that read "There's no Replacement for Displacement!"
...and now I drive a Mini

 

Melted a set of the Brisks in my Manic tuned R56JCW running 25psi boost after 3k miles ;-(

 

DOR14LGS? What did you end up replacing them with?

I replaced my R56 JCW plugs with the OEM NGK ILZKBR7A-8G at about 48,000kms 3 weeks later I flashed my car with an Evolve Stage 3 Tune and 2 weeks after that a Coil Pack went out, this was then replaced with an OEM pack. A few weeks later another Coilpack went out so once again replaced with an OEM coilpack, I was pretty fed up so I decided to order the Ignition Project uprated coilpacks. Upon installing them cylinder 3 misfire on the OBD2 showed up so I put the stock packs back it and diagnosed it to being the 3rd Cylinder Sparkplug going out, luckily I kept the older plugs I had previously changed out and all went back to normal, should I be aiming to go for a colder plug?

 

Terry,

The 5992s are they ok to use on a bone stock MCS gapped at .32? (only asking because its a step colder)
