Spark Plugs

[calais24/7]

I am changing my plugs at the moment and noticed that there are two differant types listed for the vl. In NGK it has BKR6E-11 and BCPR6E one was on the computer the other one was listed in the book?. Which one is best? And i took the BCPR6E's out of it when i changed them and put the BKR6E-11's in.
Cheers

i use the BCPR6E S11 <------- 11 meaning the 1.1 Gap

[nasty1]

i used the 11s but re gapped my plugs to 0.8

[calais24/7]

Cheers guys, was their an improvement when you re gapped them?

[nasty1]

is your car turbo?i gapped mine to 0.8 so when my cars on boost it doesnt blow the spark out.

other ise just leave them at 1.1 or 1.0

[calais24/7]

Nah its N/A, I'll just leave them be they do the job

sorry to bump but its better than a new thread

what are the best spark plugs and leads i should use for a n/a auto vl?

[detox_nath83]

BCPR6ES11 plugs
and go any leads for the rb30.... bosch leads super sports inductive core 590 i think
nothing crazy for the N/A

The BKR6E-11 are slightly shorter in body length (not thread) than the BCPR6E and apart from that there is NO difference...

The recommended plug is BCPR6ES-11

NGK ARE the best!!!

NGK are shit unless you get the iridium ones, there the only plegs i use or platnium plugs for n/a cars

[nasty1]

platinum and iridium are a waste of $$ in my opinion.

cant go past ngk bosch is poo

[Nackerz]

no platinum and iridium from ngk other wise there stock one are shit....bosch ha there even worse lol

[nasty1]

ive never had problem with stock ngk's

my mates 300+rwkw r33 had those plantnum shit things in it.it wouldnt run good we gapped the stock ngk's to 0.8 and it never skipped a beat.

yeah i have heard bad reports of the iridium and platinum plugs from various sources saying dont waste your time,,,,
i guess its personal preference, just like rims :P

An insight

"The newer elements used in plugs are for longevity, not performance. They'd have you believe they increase performance but in reality, they decrease performance as a tradeoff for longevity. The most conductive element used in plugs today is STILL good ol' copper. But, guess what? Copper wears out fastest of all elements offered today. Platinum lasts longer but at the expense of performance. Platinum is less conductive than copper which will yield less spark, all other things being equal. Iridium is somewhat more conductive than Platinum, not as conductive as copper, but lasts longer than copper.

So, you have a list:

Copper - short life, best performance (and mileage)
Platinum - long life, worst performance
Iridium - long life, performance between copper and platinum (hence their pricetag)

I run copper in all my vehicles because I don't mind changing the plugs every 20k miles or so. If I ran plat or iridium, I'd run them 40k or so miles at the expense of slightly reduced performance.

In reality, most people will never notice the difference in performance, so the longer lasting plugs are very popular. I notice it a little but I'm very in tune with how my vehicles run. Most people would never know the difference unless they checked mileage, then they might notice a mile or so increase with the coppers.

As for the arms, well look at it this way - only one arc can happen at a time. That basically means that only 1 arm can be used at a time. Funny, eh?

As for too hot, well that can happen with any type plug if it's the wrong heat range and/or wrong gap."

I find it very difficult to change the plugs so would go for longer life plugs

[nasty1]

unless you have a custom plenum hehe

[detox_nath83]

haahh i have no probs at all as long as u have an extension/spark socket/ratchet and universal joint its easy all out in 5 mins.....for bow down well all out in 1:30 :P
