Spark plugs

[Nismo_line]

i bought the BCPR6EIX-11 and everyone is saying that the iridiums the tip will blow i just put mine in a ran great with them put 100km on them just wondering if i should change them to coppers or leave them ??

[markc32]

u know what from all thats been said id stay away from the iridiums....im using the ngk vpower coppers atm...bcpr6e-11

well i just spent 40 bucks on plugs and some say they are fine some say they are bad anyone have issues with them if so what plug should i run on my 92 gts fmic turbo back exhaust intake and 1 bar of psi??

[markc32]

i bet some1 will say use one heat range cooler and gap to .8mm instead of the 1.1mm and use copper..i dont suggest using the STANDARD copper coz it wont last long...dont use champion plugs coz they seize on the head....so if it was my car i say use

ngk vpower jis bcpr7e or iso bkr7e both are .8mm gap and cooler.....does the gts use a stock heat range 6? if so 7 is cooler good for one bar boost

or some1 correct me

platinums niridiums are marketing and for ppl that dont want to replace plugs 2x a year or 3....but its proven for turbo cars like ours....plats irid are useless

A bit contradicting no?

NGK Vpower, both JIC and ISO versions (BCPR7E + BKR7E) are standard copper plugs..

Stock plugs are PFRA5-11, platinum. Alternative plug was the FR-5, Std copper.

Heat range for a stock GTST plug is a 5, 1 colder would then be 6 and so forth.

Copper plugs will last a season, but tolerances change more rapidly than iridiums due to their relatively low wear resistance.


Heat range of 6 is better for stock application. Runs cleaner and has no break ups on hot / high revving applications.
7 is good for a car that is running considerably more boost thus higher temps.
Plug gap should be .8, regardless of the stock being 1.1.

Do it next time. They'll be fine for a season depending on engine mods, but im assuming youre running stock right now so i wouldnt stress.

We know. But this has been discussed NUMEROUS TIMES. Avoid iridiums, for both reliability and price.

PFRA are basically BCPR E and BKR E but the S (std) version of these. Also, PFR's are platinum, also not GREAT for boosted applications..

Copper.
