Spark Plugs For 750hp..?

[GreeceS13]

What spark plugs I must put for my R32 GTR with T04Z?

[R31Nismoid]

NGK coppers

[r33_racer]

ice cold spark plugs for operating temps and then ambient temp ones for when its cold and missing like a bitch

[PM-R33]

BKR7E or BKR8E possibly?

[GreeceS13]

I bought the engine with Greddy 8 iridium but second hand unknown condition...

BKR8E are the cheap or the ididium?

Better to use iridium or the cheaps and replacement very very often?!?

[R338OY]

Use the NGK coppers (cheap), get a heat rating of 8 or 9 i'd say.

You change them every 15-20,000kms. Earlier if you're worried

[GreeceS13]

They are so cheap that I will replace them every 3000km... and yes I am worried!!

Nothing better with iridium spark plugs?

[R31Nismoid]

Nothing other than the price

[PM-R33]

Iridium and platinum last longer, thats about it. For normal every day types of cars they are perfect because you never have to worry bout them and just keep them in there forever. In a modified car which usually fouls up plugs quicker than a standard car would, putting in coppers every 5000-10000km is the most ideal thing for performance and it works out a lot cheaper.

Agreed!

NGK R-5671A-8

good plugs

[GreeceS13]

Hmmm... service manual says NGK PFR6A (platinum) so the replacement is BCPR6ES

So the plugs I need are

BCPR8ES

or

BKR8ES

Also how much gap?

[PM-R33]

Keep it set to the standard 0.8 gap and see how she goes. If your ignition system is up to scratch it should be fine. If it starts missfiring badly try gapping them down bit by bit.

[GreeceS13]

Thanks!

But which plugs?!?

[PM-R33]

Start at a BKR7E at its standard 0.8 gap and see how it goes, if it breaks down gap it down a bit. If you still have dramas with this try going a higher heat range but i think your main concern is going to be the ignition system, maybe look into a HKS twin spark system if you have spark break down issues.

[GreeceS13]

7 heat range?

Noway! I need 8 or 9 but I don't know yet which spark plugs use the rb!! BCPR or BKR??

[robots]

BCPR for RB26. BKR for rb25.

[r33_racer]

grab a set of both 8's and 9's. Tune and run car on 8's, pull them out and have a look how they are running and how the engine is running and if you need to go colder then try the 9's. I wouldnt think you would need to goto 10's though.

[GreeceS13]

Yes guys but the next questions is where to find BCPR9ES??

Very rare plugs

[jantolis]

Bursens were the only place i could find the BCPR7ES in my area. Maybe try them.
