FS: 6 x NGK PFR6G-11 Spark Plugs, NEW

[ouijabored]

My Galant is being sold as the gearbox is dodgy and I am purchasing a smaller auto for my wife to learn to drive in. (I will get a new toy when she passes her test) I have 6 brand new spark plugs still in the boxes if anyone is interested. I paid around £60 inc delivery and I am looking for £45 inc delivery for them. Payment by Paypal.

Brendan, these are gapped to 1.1mm and aren't suitable for the VR-4, which should have plugs gapped to 0.8mm.

They are however highly suitable for the N/A V6!

Just regap them can you not?

[elnevio]

I'm sure that it's not recommended. Not sure of the reasoning, but definitely with iridiums, and probably with platinums, regapping is not recommended. Gapping is fine with coppers, I would have thought. I guess it's something to do with the hardness of the metal in question, and regapping may cause microfractures in harder metals, which I expect wouldn't be good for carrying precise electric charges.

Any knowledgeable ones able to provide enlightenment?

[AlanDITD]

Had a quick look on the world wide web, and you are 100% correct. Didnt know that.

Bloody hell I think I have the wrong plugs in right now... Got to change 'em then

what are the correct plugs for a legnum then?

NGK BKR6EIX or BKR7EIX if you have upped the boost. Gap is 0.8mm

[AlanDITD]

been recommened to me to close the gap to 0.7m with the boost up. Guessing this is to stop the spark being blown out as easily.

Any opinions? i havent done this yet.

I think 0.8mm has been pretty tried and tested here.

Electricity if a funny thing though. The wider the gap the higher the voltage potential that builds up to before the gap breaks down and the spark happens. Sometimes a bigger gap can yield more energy in a spark provided the ignition system can supply it. Surface discharge plugs are awesome in some of our kart engines and they only use magneto ignition.

Even better my alfa uses lodge 2hl plugs which are like surface discharge with flat plates pointing to the electrode. I think they stopped making them now sadly, but they are far better than super 4 plugs etc as they don't shroud the electrode and create some good turbulence right near the electrode. You never gap a 2hl as you cant. I will post a pic later if i can just out of fun as they are an interesting plug.

One manufacturer that really interests me is Brisk Spark plugs. They have some really innovative designs like the halo and the stack plug etc claimed to give better efficiency and power. Apparently the plugs we all know and use are still being made on the same machinery that was built 50-60 years ago so basicially nothing has changed.

Also search firestorm plug for something really weird and wacky that sounds good.

Even pulse plug although these are expensive, they contain a gap inside then and a capacitor to act like a CDI ingnition and make the spark hotter.

I have seen NGK PFR6J-11 recommended for the vr4 is this right?

Read post three above!!

[Dom B]

That post is about pfr6G-11 i said 6J-11, what does the G and J signify???

I am holding the NGK catalogue and they say it is suitable and whats more they are not gapped, the cat says you gap them yourself. The ones that are gapped in the catalogue have the dimension the ones that aren't gapped have an X meaning you gap them yourself.

PFR6J-11 is a copper core plug so isn't really relevant to that discussion about not gapping iridium plugs.

It's all so confusing i could do with a ngk part number decoder. there isn't one in the catalogue unfortunately.

[elnevio]

Get 'em, put 'em in.

NGK make spark plugs, I don't. They know more about spark plugs than me.
