Ngk Bcp6es

[letemlaf]

hey guys

i was recommended the NGK BCP6ES spark plugs.

i rang a few auto stores and they only have NGK BCP6E which they rekon are the same plugs, but i was told to watch out to make sure its the NGK BCP6ES with the S on the end.

anyone (in perth?) know where i can get hold of them?

[jonn]

Try Coventry's.

[letemlaf]

ok ill try them tomorrow

is that where you get them from?

[BHDave]

you want bcp6res for .8mm gap or bcp6res-11 for 1.1mm gap (which is the factory recommended gap), repco has em in stock all the time.

BCP6ES or BCPR6ES

BCPR6ES, which are the ones I think you mean, should be very very common, if you cant find them at any marlows, see if they have BCPR6ES-11.

The difference is the 11s are gapped to 1.1mm, so just regap them to 0.8 and all is good.

[Zahos]

difference is

BCPR6E = copper, resistor, V-groove

BCPR6ES = copper, resistor... (no V-Groove)

The V-groove helps produce a better spark as there are more edges on the electrode. I would prefer BCPR6E over BCPR6ES....

[Busky2k]

Ditto with Zahos. The V-Power plugs are the way to go!!

If i could tell you one thing it would be this. PLEASE buy the BCPR7E(S) and gap them to 0.8mm if they aren't already.

If you run more boost than stock (or intend to) you'll be much better off. They're the same thing as the plugs you mentioned but one heat range cooler. They are no more expensive.

Hey Adrian,

I found I was worse off with the 7 heat range. For a daily driver, they fouled a-lot quicker before I got my SAFC than the 6 heat range would. The standard heat range for an RB25 is 5, so 6 is one cooler. I would disagree with getting the 7's unless you got quite a few mods 200rwkw++, and stick with 6's for basic mods, and 5's if completely stock...

If you run more boost than stock (or intend to) you'll be much better off.

Like I said.

yeah i installed the 7s yesterday and they seem good, the only thing that sucks is the plugs i pulled out of my car where HKS spark plugs, does anyone know if these are better then the ngk

[letemlaf]

well i got the 11's and gapped them to 6.

put them in today, and it was amazingly a big job for something so simple.

took about 2.5hrs

guys, if you've ever tried calling NGK for a recommendation, they have actually told me to sell BKR6E plugs to skyline drivers if they want a cheaper copper core option to the more expensive Platinum and Iridium tip long-life plugs (only differerence is the greater resistance to fouling)

Reason behind the "K" instead of the "CP" is that the "CP" is a projected tip type plug and NGK have discovered that the "K" recessed type plug seems to complete combustion more effectively due to the shape of the cylinder head "squish zone"....

that will add more discussion to your thread (adding to the numerous hundreds of other spark plug threads on here) Oh, and yes totally agree with the gapping and heat range advice above. Buying NGK plugs without the "-11" should give you the default 0.8mm gap.

sweet i just bought new plugs on saturday, and I got bcp7's was stressing cos i thought maybe i should have got the 6's. i feel better now though

[Black_CSR]

I pulled out my BP7ES and they were black and fouled.. running 370HP @ 20psi. I'll go down heat range and go with 6. My tuner told me to stay with 6 so it can get hot enough to clean itself and not foul.
