I want to buy spark plugs that are one heat range colder. I'd like really good ones as I've had some stumbling issues on cold days in the morning. Can I buy these at auto zone? If so what's the model number or name. If I can't get them in a store like that can someone give me a link. Also what's the best material? My car only has 35,000 miles on it. Do I need to change coil packs or and wiring? I'm going for Manic stage two and I'm only a catless downpipe away from getting it.

 

Get the ones listed in my signature (it is what Manic recommends). And typically you cannot buy these at your local auto parts store.

 

Thankyou but I don't see any signature. Any chance you could copy paste it here?

 

ngk ilkr8e6

 

You might want to gap them down a little depending on boost

 

What would you reccomendation for that? Also what would be the benefits of doing so vs not doing that? Also what kind of tool would I use?

 

A good gap Is 0.6 mm

 

So I'm about to order these plugs. Is anyone else using them and reccomendation them? I'm really close to the manic tune and I want to address this before I get it. They said to make sure my ignition system is good to go and I stumble on cold mornings a little bit. Now that it's warmer I don't have any problems though. So pull the trigger? Advanced auto parts has autolite ones that are the same specs. I feel like I should get these though since these aren't the stock plugs and Imore taking your guys word. I don't know much about plugs but if you run and reccomend them ill go for it

 

Don't use the autolights. Use NGK or the MiniOEMs. Don'e mess about with "off brands". See my thread here

NGK ILKR8E6 --- aka NGK 1422 (the stock number). Manic recommended them for my stage 4 too. Apparently these plugs are good for most of their stages. I'm still on OEM coil packs and these plugs are a big improvement over the OEM version. The "6" in their part number translates to "0.6mm" (or 0.024") gap. The "8" indicates it's one range colder than the OEM version --- ILZKBR7A-8G (heat range 7, gap at 0.8mm).

Be advised that you'll need a different spark plug socket --- ⅝" hex and thin walled, for the NGK 1422 --- hard to find. I got mine from a Snap-On truck --- cost as much as a set of the plugs. My plug source was Amazon --- big selection of vendors.

 

oldbrokenwind is correct about the 5/8" socket. I went to Walmart and found a cheap Stanely ($5) that was thin walled enough to fit. Kobalt from Lowe's would not work nor would a Craftsman.

Whatever you do, do not force the socket down into the hole. It can get stuck. If you feel resistance, stop and remove the tool.

 

Hey guys thanks for the help. I'm about to order them right now. What is the socket for the regular ones?

 

14mm thin wall (12 point)

 

If not too late....go with the Brisk 8 or 12.
Burning fuel properly and efficiently is important and given my personal test results and the fact that silver conducts the charge with 580% more efficiency, the Silvers just make sense to me.

 

Brisk MR14YS is equivalent to NGK heat range 7 --- OEM.
Brisk MR12YS is one heat range colder --- equivalent to NGK heat range 8.

I could never get the 12's to work at high RPM's. Tried different gaps --- nothing but misfires.

I've also read that our ignition coils are designed for Iridium, and may not perform properly with a silver plug. Contradicts Indimanic, but my results indicate NGK 1422 is worth keeping.

 

I use these https://www.amazon.com/gp/aw/d/B00UDK59F8

Gap .022

Burger tuning gives the recommendation but are cheapest at Amazon. I did buy their custom socket since it is good price and magnet.

I used these plugs on many MINI. Worked well on all N18 turbo engines. I read they work on all N14 and N54 and N55 as well.

 

Interesting the Brisks gave you some issues. I've read that silver is some 500% better at conducting electricity with way less resistance.
Logic would say that OEM coils would like that.
I do run the IP coils though.
The only issue I had w/ Brisk was the center electrode would melt

 

If people are having issues with silver then I'll probably stick with the NGK. I found them online for $40. No stores around here seem to have them though.

 

NGK 1422 seems like the way to go. Just installed mine. So far, so good. 30k miles later, we shall see.

 

The 1422 never gave me an issue but I feel the throttle response and power was noticeably better and with my tune I felt they are worth it.
When a driveability issues does arise, first thing I do is install the 1422 to rule out secondary ignition problems
Cannot go wrong with 1422 for the average Mini

 

I run the Brisk QR12LS not the MR as recommended by Brisk
Great smooth power delivery.

 

Yeah I'm sold on the 1422 plugs. I just sold my JB+ since within the next month or 2 I'll have manic stage two so I'm using that money for that. I'd imagine it's still safe to go with Colder plugs though right?
