Yes but it's not even all about heat range. We run projected tip plugs in boost and NA setups. If you run projected tip plugs on a Nitrous setup around 150 shot and above they can act like glow plugs and cause detonation.

Most don't run Iridium on a Nitrous car because they are expensive and get changed frequently. You have to run colder then boost or NA, plus the non projected tip tend to foul easier.

My opinion would be to run a 150 shot on a non projected tip 7 heat range. Above 200 you really should consider direct port instead of a plate for better distribution.

My best advice would be to call Dave or Brandon at Nitrous Outlet and get some professional opinions.
