BCPR6ES

i'm wondering,

when exactly do u need to move on to colder plugs?

would those plugs work with higher than stock boost?

[NYTSKY]

For every 50kw gain at the motor get the next colder plug.I have BCPR7ES in mine.Already gapped to 0.8mm out of the box.

7's are really to cold for a street driven car, id be suprised if they came out "clean"

Generally there is no formula for heat ranges, rather you have to read the plug and make an educated decission about whats going to work.

For a mild street driven car 6's are the way to go. I usually run 6's if I drive it around and change to 7's when I know its going to get flogged.

Standard boost = BCPR6ES – 11

12 psi = BCPR6ES – 8

Up to 19 psi = BCPR7ES – 8

Over 19 psi = BCPR7ES – 6

BKR6eix for me

[Risking]

If your gapping down to .6 you have a serious ignition system problem. Im running 2 bar with .9 no worries. I set up all my cars and customers car similarly.

V-power BKR7E

Or BCPR6ES Gap 0.8mm

NGK coppers, the BCP6ES as people have mentioned.

Alternatively a swap of plugs, from the daily driven 6's to 7's for a track day is a better solution again.

Platinums and irridiums are a big waste of money. Don't bother with them.

NGK coppers wont last more than 5000 kms, platniums are ment to last around 30,000+kms depends on what mods

[Risking]

Coppers will last much longer than 5000Km's I generally use them for 10-15K.

And platniums have an expected life of 100,000K's in a "normal" engine.

But coppers make a better spark. Platniums / iridiums etc. are ok for stock or na cars but i'd stick to coppers for anything forced induction or making decent power.

platinum plugs for stock passenger cars and nerdy drivers.

For many years I've used copper plugs for the basic reason that plugs are a tuning consumable and a tuning indicator. When you start into performance tuning even at very mild levels irridium and platinum plugs become a waste of money. Not only that but being coated in a substance that promotes a very clean surface means they are pretty useless at acting as a tuning indicator.

hey how long do your copper plugs last before you need to replace them.

or you notice loss in power.

Just pull a plug at oil change intervals and check the electrodes. If they are worn then replace the plugs.

yes changing oil is alot easier than changing plugs in a skyline lol
