R34 Gtt Advise

[rgr34]

i have read a few threads about this dilemma of what is best and been left abit confused on what to choose, i am changing the spark plugs after 4 yrs...lol

although the car runs good i assume its running a iridium type long life plug, day to day normal driving, i do notice when driven hard i get the hesitation which has been covered on other threads before.

Car is a r34 gtt has cat back exhaust, boost set at 11psi and pod +cai....

alot of diferent plugs being suggested part numbers bcpr6es,bkr6e1x,pfr6a-11,bkr6eya etc..

i am thinking to try a heat range 6 plug and .8 gap due to the extra boost, does anyone know the ngk part number? i want it pre gapped dont want to be mucking around regapping them....anyone can clarify what they run in there r34 with similar small mods?

im running BCPR6ES - 11 in mine,

turbo back 3" exhaust and boost set to 11-12psi, no issues if i give it a boot full, im sure the gapped version of the same plug is simply BCPR6ES - 8

NGK copper plugs

BCPR6ES is the copper, heat range 6, 0.8mm plug and is the one you want.

don't bother with iridiums. waste of money. cost you 4 times as much but don't last 4 times as long

will be buying trying some BCPR6ES next service..... i decided to check what plugs the car had in it , turns out there ngk iridiums and after at least 25,ooo kms they were still good even the ground looked ok.....

What a pain it is just getting to the spark plugs thou lol.... i read alot of ppl change them every 5000kms, i dont think i can be bothered doing it that often im thinking 10,000kms intervals should be alright?

[mad082]

i changed my coppers at 10,000kms and had no issues.
