Spark plugs at stage 2

[rtd]

Just out of interest has anybody upgraded their OEM spark plugs when they've gone to stage 2

[leet]

I'm interested in this too as am about to replace them in preparation for tuning. Everything points towards stock though

[Ungjaevel]

I don't see the need.

When you say "upgrade" - what exactly do you mean?

Exactly that upgrade the OEM plug to a different one

[Ungjaevel]

Ok, sorry I'll specify: What exactly do you wish to achieve with an upgrade?

I take it he means like ngk do one step colder plugs for some cars although I'm
Not to sold on them to be frank

[Ungjaevel]

AFAIK there is no need to go colder on a Stage 2 map.

If you go beyond; hybrids, ICs etc then that's a different story.

Or by all means if you had any other goal in mind - do share!

yes essentially that - was interested to know if any owners had upgraded their plugs to a better preforming plug to aid the map however, it seems the OEM plug is more than efficient at stage 2.

OEM NGK

If you want the final answer I would ask Classba. He had the most Bhp c6 on this forum. I'm stage 2 standard plugs no issues

[Ungjaevel]

Yeah but he had (way) beyond Stage 2.

Just go with OEM plugs, they're fine.

He did and he would have an informed answer for the OP

What ngk spark plugs for rs6 c6?? Any in particular? Codes? Help please

[Fatneck73]

I’m stage 2 I ‘think’ (QST call it stage 3) with standard plugs...no issues at 749bhp/938lb/ft

TBH you be nuts to run std heat range on stage 2 plus (below is the premium option but std plug but one cooler is fine),

we use these in all our in house tuned cars (modified stage 2 plus);

DENSO IK01-24

or NGK

R7434-8 (i use these in my own car at 645hp at all 4 wheels)

Both have the better electrode design, which reduces the chance of det damage and is a few heat ranges cooler.

STD setups or stage 1 or 2:

DENSO IK01-22

or NGK

R7434-7

Better tip design but only one heat range cooler.
