Plugs for DC2R

[Zilli]

Hey all,

Damn its hard finding plugs for my car. Couldnt find anything at any parts shops.

No iridium substitute, unless i got the 1.1 mm and regap it to a 1.3. Not too keen on that to be honest. No one even stocked the platinum one in the correct gap.

Even Honda was closed today, dammit and i was g'd up to change.

Anyone have any advice, as the listed plug for the c7 is 23 a peice, i dont mind paying but i want the best i can get, is the iridium really better? and if so anyone have an idea of a subtitute plug?

NGK Platinum PFR6G-11

don't have to worry about regapping the plugs and it is the recommended plug for DC2R.

i have tried platinum and iridium before on my previous GTR and it did not make much difference at all imho.

the book states the PFR6G - 13 is the right plug

what is your source?

I've got some NGK Iridium IX here at home. They were bought ages ago. Code is BKR6EIX-11. Would these also fit the DC2R?

page 185 of my owner's guide and heaps of thread in ozhonda.

hmmmm

i wonder why the NGK book says 13

[hebe]

Read your user manual for the DC2R...It lists the NGK model code.

That's how I bought mine and it was readily available at Autobarn as well.

Great stuff!! i never thought to go to my user manual!

ok, now the 13 plug didnt have a Iridium substitute, i think the 11 does, butt my local auto shop doesnt have them in stock.

Quick question, im still got the factory plugs in the car, ie they are about 7 years old, is there a time limit on the plugs in terms of there effectiveness? or is it just 100000kms?

i fitted IRIWAY7's to mine, $25 each from Active Auto Sportique, Lidcombe...

need to gap them manually though... (dunno why book says 1.3 gap? seems pretty high)

[TOU93]

PFR6G-11 and PFR6G-13 are the same plug but the number on the end denotes the gap 11 = 1.1mm and 13 = 1.3mm

heres the confusing part, my car is due for its serives and i was goin to do it today, i like denso iridium plugs(you can get from any toyota spare parts) but for the JDM engine(B18CR) it says use a gap of 1.1mm gap and for aus engine(B18C7) it says use a 1.3mm gap.

seeing as the engines are 98% the same, i dont see the need for the bigger gap in the aus plugs?

[Zilli]

hmmmm interesting.

I dunno...

You'd want to run the largest gap that your ignition can cope with.
Problem with high revs is that the coils sometimes cannot keep up making it harder to spark across the gap, hence a smaller gap.

A larger gap would potentially give you more efficiencies if your ignition system can keep up.

Maybe the Japanese ITR revs higher than the AU variant?

the australian manul dictates an 1.1 mm gap
