Spark Plugs
I plan on installing my plenum spacer soon and while I am donig that I want to change out my plugs. I know I dont need to but I dont like leaving plugs in for that long. I am at 34k now and I have to do it.
My question is this, are there any plugs out there that are proven to be better that I should buy(NGK iridium, Bosch +4, etc.), or should I just stick with the ones the manual tell me to go with.
Thank you.

Search the forum, there are many talked about it.
My research showed that the denso iridium is good, the right part# is IKH16
for 350z, some use one step colder which is IKH20.
You can go to denso's web site for detailed.

It depends on where you do the majority of yuor driving. The plugs from the factory are figured as 50/50 split on highway/city driving. If the majority of your driving is in the city, you can go one way, highway the other, but I can't recall which.
