What do you recommend on a stock motor? Would I see any benefits running a 1 step colder plug or should I just stick with OEM specs?

If you are running boost levels>stock, you may benefit, otherwise stick with the factory heat range.

10-4, thanks for the input.

Followup question: Which brand? I hear good things on this forum about NGK and Denso so I assume they're both comparable?

It looks as if people are slowly moving to NGK because of some recent findings of cracked porcelain on the Denso's.

The NGK will need to be regapped because the out of the box gap is a bit large for the ms3.

I hate to say it rob, but the matte black wrap you have on your car looks DOPE..... how much did it end up costing you?

I have NKG and gapped to .030, I will be running 19.5lbs when I retune.

@rfinkle2 answer my question mang

Only use plug gapper tools to open up the plug gap; not to actually measure the gap. Use a set of feeler gauges to measure gap properly.

From reading the thread, since I currently only have a cobb sri and I am running stock boost levels should I go 1 step colder or just stick with the stock heat range. Also have the denso problems been worked out? Thanks

if you had read the thread, you would have read, a whole bunch of times, that stock boost=stock heat range plugs.

maybe it is time to work on the comprehension part of reading?:loveweed:

thanks for your input. but also some of the people that are on stock boost are running one step colder and was hoping to hear from them on there opinions of how the car is running with them. i do comprehend reading thru posts and searching before I post. that is the reason that i donated to help the forum stay up and running for me to gain knowledge as everyone else. fyi...:loveweed: ..has never been in my system.

I'm currently running ITV-22's while I'm in between tuning solutions at the moment.
I am currently still on stock tune and boost and it runs fine.

@speed0450 you want to run the hottest plug you can without pre-ignition.
