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

Oh, and they’re less than $13/plug so no more gouging by the dealers/tuners!

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.

Gapped mine to .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.
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

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

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
Hope this helps
The bosch plugs have now a range of 5. Better to upgrade to the ngk 8´s?
