Hey guys,

I've decided its time to get some new plugs for my 33 as i can tell the old ones have had it as the car is backfiring alot, now ive read through the forums and stuff but i want to know what everyone recommends. Ive read that RB20DET plugs might run cooler? and what gapping should i get, i will be purchasing iridiums. Thanks guys any advice would be helpful!

Thanks col thats what i needed to know, unfortunatly the coil packs will be comming later on in the year haha

best plugs to run would have to be NGK coppers

BCPR6ES

they are gapped at 0.8mm from the factory

you have no need to run iridiums they are no better than a copper plug and cost $20+ each rather than $3 each for the coppers...

BCPR6ES

To be more specific:

BCPR6ES-8 = 0.8mm

BCPR6ES-11 = 1.1mm

go 0.8mil

From the spark plug thread that I started in forced induction, I learnt that the gap depends on the boost you are running, for stock the gap is 1.1mm if you are running 12psi or above 0.8 is recomended, as for plugs there is no perfomance gain to be gained from any but the life of the plug is greatly increased with platinum (80,000ks) and better still with iridium (100,000-160,000ks) compared to coppers which are recomended to change at 5,000ks although some say they last to 10,000 upto 40,000, if you can change them yourself go the coppers recomended above, I am using iridiums and they have been in there for 60,000ks now and still good, I know because I keep pulling them out when something else stuffs up. Price wise they arent worth it really, I have been told that they are good in motors where changing the plugs is an absolute pain.
