Hi Guys, just wondering if the rapid fire #5 sparkplugs are equivalent or 1 step colder, or hotter, vs. the plugs that you receive with the gm blower kit for 2000-2002 cars? Thanks
The plugs that come with the kits are one step colder plugs. AC delco R42LTS

i am not sure on what heat range colder they are, i want to say 2, but dont " me.
i am using them for a while now and they work great, many many other 2.4l boosted guys use these plugs with great luck.
killer quad told me about these plugs and he runs 11's on his quad 4 and lots of nitrous.
here is the gm part # 25164643
i will e mail him again and see what the # is for sure. as i know there is a rapid fire #5 platinums.
the #5's i saw on ebay , didnt look like our plugs
they had a washer seat , and not a tapered seat
since then ive been confused about them
ive been running the 4177 ngks' , and im happy with them
