Spark Plugs, What To Get?

[phat_man]

i need to know what spark plugs to get, i did a quick search but didnt get the info i wanted.

atm my rb20det doesnt have many mods, its running 10psi boost, and that should go up in the not to distant future.

what i need to know is what gap to get, and what plug... iriduim, platinum, or copper?

thanks in advance, issa.

Most people just use coppers as their cheap, I use BCPR7ES with a .8 gap, my car missfires with anything else, I also change them every 2nd oil change.

yup i asked the same question here about 3wks ago.

consensus is......iridiums are good for longevity etc,....but are about $20-30 each.

but coppers conduct charge better, but need replacing more often. so when u change the plugs about 4 times... it adds up to about the same price as a set of iridiums..

go coppers

BKR7E 0.8mm gap

BKR7E 0.8mm gap

is .8mm gap to small of a gap for only 10psi, i dont plan on going past 10 untill i get a fmic, that could be in about 1 or 2 months.

also what cold rating. thanks.

i was running 10psi for a while and that gap is fine. BKR7E are 1 heat range colder than BKR6E.

NGK iridiums made a big difference down low on my RB25DET. Much more low end torque.

Had HKS ones before, now I use NGK Iridiums / Platinum. Plus I got Spitfire Coil Packs and a Di (Direct Ignition) bridge.

Standard NGK coppers, BCPR6ES.

They are already gapped at 0.8mm so put them straight in!

+1, thats what i used on my 32, and didn't have any pinging or spark problems.

i've got a set of NGK platinums for sale (PFR6A-11) for $100. They're normally about 20 each

so just go coppers then ay?

my 32 starts to miss a lil bit at round the 4800 rpm range so think i need new plugs and will then need splitfires.

Yep, I just put a set in my car again.

Getting it ready for a tune now.
