Best spark plugs for B18C7

[benson]

we run $4 plugs. It works.

[tinkerbell]

the reason for the use of platinum and iridium is not because the work BETTER...

it is because they work the SAME for 10 to 20 times LONGER duration...

[hebe]

I was told that the k20a2 used Denso iridium plugs as oem... cant remember who by though

If you want to know what the stock plugs the K20A2 uses then just look in the manual, it tells you.

(just so you know, platinum and iridium are "elements".

alloy has nothing to do with them...)

an alloy is a combination of different elements (usually metals).. a metal this is a mixture of platinum and iridium is an alloy.. that's what i meant.

I did Yr 12 Chemistry.. i know what an element is

[tinkerbell]

oh, right, well, to answer your previous question, no - it seems they are not an alloy, the plugs seem to be 'tipped' with two elements, one on each side (center iridium and ground platinum)...

correct me if i am wrong...

sorry for bring a old thread up but if i was going to go i/h/e + kpro would i need to use a cooler rated spark plug ?? or the stock 1 would b fine ??

are you suffering from deonation or pinging at high RPM?

do you circuit race it?

do you spend longish periods at high rpm under load?

your tuner might suggest it anyways... check with them too - even if you are not going to race it...

Just ask tuner (i assume it's Adrian) if you need it

[supersteve]

just as a side issue related to plugs i was running octane booster on std ngk plugs platinum type and racing at phiilip island got 20k out of them before replacing , this is what my mechanic seemed to think anyway

[tinkerbell]

is that good or bad?

i avoid octane booster at all costs.

[l3vnd1]

I'd assume thats bad as platinum plugs are designed to run a lot longer than 20K

Why do you aviod octane booster Dave?

[fatboyz39]

We just use $4 plugs in our engine. FFS there spark plugs, wont gain blardy 10kw with em.

Octane booster very bad for plugs!

Alot of people dont realise that the exotic plugs maintain their gap for extended periods opposed to $4 plugs running well to begin with, but then the sparks wears away the poles it needs to arc across causing the spark gap to become larger over time causing you grief, if changed often then performance wont be affected with these cheaper plugs.

OEM use the exotic plugs for reduced maintenance, better emissons, performance, and fuel ecomony over a longer period of time, 100k for example with those plugs.

There is plenty of info on the net regarding them if you wanted to learn abit more about it.

[tinkerbell]

yeah, you gain nothing with exotic plugs, but ohhhh so much to lose with $4 dolla plugs...
