Thoughts on running one step colder spark plugs....
Just doing research on different options for the F and noticed on RR-Racing website that they sell one step colder plugs for track use because the F runs pretty hot in track conditions: http://www.rr-racing.com/Lexus-IS-F-...-p/ngk2309.htm
Here are a couple threads I found from over the years below (they're not that long):

Anybody have opinions either way?? Also does anybody know what heat range that the engineers chose for the 2UR-GSE? And if they were meant to carry the load for extended track day conditions especially when it's hot out??

Yes. Read about what heat range means, then make an intelligent decision about what you need. The most important thing to remember from this tech article:
So running a too cold plug is just as dumb as running a too hot plug.
The heat range must be carefully selected for proper spark plug thermal performance. If the heat range is not optimal, then serious trouble can be the result. The optimal firing end temperature is approximately 500°C (932°F) to 800°C (1472°F). The two most common causes of spark plug problems are carbon fouling (< 450°C) and overheating (> 800°C).

good read and info. Was just curious when I was browsing RR-Racing website and ran across those plugs and it sparked (no pun intended
) my interest in who runs colder plugs in the F?

^^^^^^
Interesting, Let us know what you find out! I wonder if they changed the plug for any reason??

Want to revisit this. Has anyone gone with 1 step cold spark plugs? Just got off the phone with RR and they recommend them for a FBO w/ tune. Just having second thoughts because it doesn't seem like to many people go with them unless you have a Nitrous / SC. Car won't see the track. Just a weekend getaway.
