They are not only better for that but safer also. Like jwick said, really all fi kits should have them.

Here's the part number for the plugs I got,dilka8a8 ,gtr plugs

Well ..... I didn't get any plugs with the kit I guess I'll plan on gtr ones when I change them out

Either did i, I ordered them from Cody at nissanraceshop.com,great to deal with

Change them as soon as you can. You shouldn't be running stock plugs with force induction!

Jinxx · 02-14-2016, 12:14 PM

What would be some signs I should be looking for with stock plugs ....I run 93 octane the tune is for 91 octane......I don't get any pinging sound and from my data logs btdc is around 20-25 at 6k-7k rpms.........also ...this might be a dumb question but from my 350z I changed stock plugs to 370z plugs (one step colder) and was running 8lbs ...wouldn't the 370z be similar at 8lbs ...as far as plug heat range ?

Don't overthink this. There's a reason everybody who adds forced induction on these cars goes one step colder.

Jinxx · 02-14-2016, 02:52 PM

Not overthinking ......but rather have more details than ....everyone does ...I understand colder plugs help with detonation ....but if the car isn't pulling timing ...then colder plugs wouldn't be needed ......I may be wrong but there has to be a point when colder plugs are needed and when there not needed. Plz correct me if met train of thought isn't right.

tiller · 02-14-2016, 04:12 PM

Every tuner I've talked to so far recommends the gtr plug one step colder,all reasons for it,i myself am still learning,new to this forced induction stuff,I guess I'll let you know how my car runs with these plugs and go from there lol

tiller · 02-14-2016, 04:16 PM

Jinxx · 02-18-2016, 08:19 PM

OK,I got the hard plastic connectors,hoping it works,pulling rail tommorow,just did the spark plugs

TopgunZ · 02-19-2016, 08:42 AM

The 370z has a higher compression ratio than the 350 so it already needs the step down. Then when you toss more heat in there it needs another step.

tiller · 02-19-2016, 09:21 PM

Jinxx did you reuse your injector clips for the fuel rail with your Bosch ev's?
