surface discharge

[psbarham]

anybody had any experence with surface discharge plugs on a road car , i've just got a set for my v6 , retail cost for the public version is £50 each , but because i have freinds in high places i have now i my possesion a set out of a works honda (sorry for the swearing) touring car ,total cost to me £0.00 , they have only done one 20 min race and are as good as new , they are the full race version and as such are not listed on the NGK website but working out the codeing they are a colder running plug , i can't imagine this will cause any problems with these lean burn engines but if anyone knows different let me know soon before i bolt them in

I was going to recommend a visit to the docs, until i read on!!

What is the difference from normal plugs?

[psbarham]

i'll post a piccy up asap , basically they spark off all sides of the electrode giving a more consistant spark and burn

[Wodjno]

Wheres the Piccys ??

[psbarham]

you are just so impatient , if you bl00dy city dwellers had kept your sodding tornado , i would have had more time to take photos instead of clearing up this mess

[psbarham]

piccys at last , the things i do to keep some people quite(glen)

[psbarham]

right , at last some progress on this , i've finally got round to doing the plugs , and all i can say is WOW what a difference , smoother, better throttle response , better pick up , more mid range , the lot this is me after the test run , if any body else want some then i'll see what i can do ( no promises ) but what ever i can get hold of i'll bring to santa pod

Would these plugs be suited to a turbocharged application?

Would these plugs be suited to a turbocharged application?

i would say they would be ok , if they can cope with a fully tuned honda touring car engine then the mild tune of a vr4 engine shouldn't be a problem . and i refer to my earlier answer of don't hold your breath

[zentac]

yes please, they are on my shopping list for the new engine.

[psbarham]

right i've been to my supplier today to get some more plugs , well the bad news is that they didn't have any , the good news is they had one set of iridium tipped DTM spec plugs , these will be given to the first person at japshow that polishs my car . if i get any more sets then it won't hurt for 2 people to polish her

whats the code on the surface discharge plugs?

[psbarham]

NGK 10 , i don't think there was anything else , i would go and look at one but as they are burried deep inside the cylinder head its a bit difficult at the mo, as soon as i get a chance i will find out if there is anything else on the steel portion

[psbarham]

whats the code on the surface discharge plugs?

the code on the iridium ones is R7435-10

[zentac]

[zentac]

Nah, I would like the plugs, but I would rather buy them than polish someones car.... hell mine only gets polished about twice a year!
