what are the drawback of installing the "colder" spark plugs

[chris_nyc]

So here it is: bought the new spark plugs LFR6AIX11; I was supposed to get the nitrous - last minute I cxled the installation after getting the full picture of possible issues..

now I haVE end with 6 nice spark plugs that are colder lol )
Can I install them anyhow? what is the damage?

thanks,
chris

if there too cold you may see spuratic misses, not so likely though if you just went one step colder, you won't hurt anything if that's what your worried about

 

[chris_nyc]

lol thanks this was a major concern
will the performance suffer?

probably not, as long as it doesn't start getting high miss counts your fine, one step colder is not so much really

One step colder is fine. I have been running them for over 85k miles.
