Base on specs, those should work, but honestly the car runs amazing on the 8's I listed that I would recommend them. Can't see why you would not run them, other than long term fouling potentially.

Oh, and I'm running meth but just for cooling.

If you ever decide to add timing for the meth, you are covered with 8's vs having to swap for the 7's. If you don;t mind doing the work yourself, then go 7's. If you only want to do it once for the forseeable future, go with the 8s

Is there overall improvement in throttle response and how consistent the car runs with the 7 heat range NGK plugs? What are the differences between oem and these?

I don’t plan on tuning for the meth. Beyond a basic tune, this platform just hasn’t respond well enough to mods for me to justify trying to get any more performance out of it.

Just an update on anyone wanting 1 step colder NGK plugs. So far the NGK 95770 ILZKBR7B8DG are working flawlessly. Great performance, smooth idle, and no blowout gapped down to .024. I’m tune, turbo back DPs, no cats/resonator, UPD intake, and 50/50 water/meth for cooling.
Oh, and they’re less than $13/plug so no more gouging by the dealers/tuners!

Sub'd. Great info, all of you.

Final update:
I’ll be running these plugs from now on. Performance is definitely up. Ran my quickest ETs and 60ft times consistently last night. I do have the meth a little more dialed in but that’s still only slightly helping the top end. The only thing I can possibly contribute the initial off the line performance gains to is the plugs.

I am @ .022 just cause its a pain to take them back out and re gap should you still have blow out. No real harm in going lower to avoid extra labour later. Use a feeler gauge and electrode bender not the slide gapper and tapping method if doing yourself.

I've recently ordered some of the NGK plus as well. Is there any downside at all to gapping the plugs to .022 vs .024?
In my case I have a biturbo E550 that only has the OE tune Stage 1 on it. Thanks.

A narrow gap may give too small and weak a spark to effectively ignite the fuel-air mixture, while a gap that is too wide might prevent a spark from firing at all.
.022 should be fine, as long as it burns fuel efficiently.

The is no real difference between the two. I go lower simply because it's a pain in the *** top change the plugs and I don't want to pull them out to regap if the are still blowing out. Tune only your not running enough boost to worry too much. Run the 7s at .022 and don't look back

Hey guys,
Just an update. Was doing some digging around as I'm shopping around between Renntech, Weistec, and Eurocharged for ECU flash. Noticed that Eurocharged & Weistec both sell colder plugs. Called both of them and confirmed that in fact they DO NOT make their own plugs but use NGK 97506.
You can find them at Rock Auto for about $108 shipped which is a steal compared to both companies selling them for $25-35/piece
https://www.rockauto.com/en/parts/ng...park+plug,7212
Interesting enough these are the same plugs people with upgraded/tuned BMW's run on the N54's.
I am planning on swapping out my OEM plugs for these. Does anyone else have any experience/feedback using the 97506's?
Cheers

Another update:
Just called NGK tech support team and spent 20 minutes with a nice gentleman.
Given the OEM specs of the stock plugs, he confirmed that the NGK 97506 will fit perfectly and that they're one step colder (8).
I know there's a few people wondering if there will be any engine harm for people just running a stock setup, he mentioned that only going up one step from 7 (OEM) to 8 (NGK 97506) it wouldn't hurt the engine at all. He suggested that maybe going up 2 to 3 steps there might be some challenges for the plugs to clean themselves since they wouldn't be getting warmed up enough.
Also from calling around a few tuners who resell the NGK plugs, they recommend for every 75-90 horsepower gain that you go up in step to a colder plug.
I will be purchasing the NGK 97506 from Rock Auto sometime next month because I am putting in different performance mods at a time to see if I notice any difference rather than all just putting them in at once.
I will report back with any feedback.
Cheers

Another update. Spoke to another two tuners and they're using HKS M45XL which are a lot pricer than the NGK and should be the same range.
Hope this helps

hey guys I am driving a upgrade turbo E63 780whp (860hp crank) with the BOSCH ZR5TPP33-S plugs and I have misfires after 4th gear pulling.
The bosch plugs have now a range of 5. Better to upgrade to the ngk 8´s?
