Spark plug for RB25DET - I know it's been done before ...

[Robo's]

Apparenly they don't do the -8 in the iridiums.  Would I lose much power if I am running with .8mm instead of 1.1mm if it could actually handle the 1.1mm.  I'm going to check my coil packs when I replace the sparkies.  Thre is a slight hesitation when boost comes on so I'm thinking either sparkies or coil packs.  I don't know how old spark plugs are....

Some say that the cracks are so small you can't even see it??  I was going o do the araldite trick if I can see cracs in them like what some of you guys have done

Thanks

You can gap them but be careful with the feeler guage, dont force it but it can be done.

I'm using BCPR7ES coppers at the moment, but the BCP and BKR don't get a mention? I've never heard of anyone on these forums use the type PFR before?

I believe PF is the platinum and obviously BCP....X is the Iridium

BCP and BKR are the copper equivalents (equivalent in dimensions and fit)

Of course they are going to try to sell you their most profitable plugs rather than the coppers.
