I went to the parts store with the old plug from my rb20 to get new ones before I start my car up for the first time. And they don't have them and can't get them. They called around to some other part stores and no one can get them. The ones I took out are NGK PFR5A 11. Need to know what I can use to replace them with. Looking to get Iridium plugs. Any help would be get, Thanks.

According to all the guys on the Skyline forums in Australia, Iridium plugs are not recommeded for the RB motors, you will get your best performance out of cheap copper plugs, $1.39 each.

I know I had some cheap ones in my Rb25 and it ran great.

 

wow is that really true?
i would of never thought of that
anyone gonna confirm this
i would jus like to know
good info thanks

 

Thats cool, but they said they couldn't even find those. They were using the # off the old plug. So I was hoping that some one would know the # for ones that I could use. Or should I just try the 90 to 96 300zx sparkplug? Hoping to Have the car running in two weeks. So it is broke in by nopi nationals at ALT. Don't want to enter it but want to drive it there with the car club. Thanks,

The Z32 plugs WILL work
