Hot or cold plug? - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

I accidently ordered the cold versions of the denso irinium plugs.  I was linked off of a japanese site so it assumed I had the 2.0 SRDET engine and not th 2.4.  I was told I could still use them with my 2.4l...but should I?  I heard it could misfire.

I believe hotter plugs are utilized for forced induction engines, therefore, the cold ones should be fine.  Confirm this w/ a local autoparts dealer.  It'll take seconds to answer...provide an update as I'm not 100% sure.

Only run Colder if you have a Turbo or NOS. Oterwise there is no need. The hotter plugs are what you need, even with a car with tons of bolt ons.

If I were to put cold plugs in my NA S14, what would happen? I will be ordering my turbo kit soon after doing the plugs and wires. I want to get the plug that will work best with my turbo, but will it do any harm to put the cold ones in now? Or should I just wait until I get the turbo install done before I buy plugs? Id hate to buy the hot ones now, only to have to buy cold ones later.

Any ideas?
