Greddy Vs Ngk Iridium Plugs

[r33cruiser]

hi guys. i was at my local autobarn today and spotted some GReddy plugs for $60. now not sure if it is each, or if its the total price for 6?

anyhoo i am having trouble finding info on them. atm i am using the standard plugs for any line owner= ngk iridium tips, $24 each!

anyone use GReddy items?

what is so good about them? are they better than ngk iridiums?

what are the chances the greddy ones are just ngk rebadged? are they iridium too? id say its $60 for 6. theres only so much you can do to sparkies yes no?

[r33cruiser]

yea fanny. found out they were $60 EACH!!!!!

all i have read is that they have iridium tips. and some silicone coating that dissipates heat.

was just wondering if anyone has used em, and if their worth the price?

Copper is a better conductor of electricty then Platinum or iridium.

Have you considered using the $4 copper ones for better performance?

[r33cruiser]

REALLY. wow that blows my mind....

was always told to go iriduim tips, for longevity and performance.

well if greddy's are just iriduims, will just keep using ngk's

(iridiums are meant to be better than copper/nickel ones)

not better (spark) they just last much longer

[funkymonkey]

I'm firmly of the belief that shorter life copper sparks are better performance as they are a better conductor. You just have to change them more often. Anyone who upsells you on expensive sparks made of unobtainium is just after a better profit margin.

not sure if that's sarcazmic or not....

yes.. iridium do last longer.

copper provides better spark but needs changing more frequently.

but the 100,000km change period listed on iridiums is a crock of crap.

especially in skylines using stock computer with mods.

they tend to run rich which fouls your $25 plugs or your $4 plugs.

lol na gtst, no sarcasm, thats how u spell it BTW.

well if u guys are using copper ones and getting good results.

i will have a look at em'

cheers

[frozenwaffles]

copper all the way!

[r33cruiser]

yup. i will chuck in a copper set for the east coast customs dyno day.

hope they work. but will gap them correctly of course.

is there a specific brand that is the best?

eg silly sollies brand or ngk copper ones?

[funkymonkey]

we use NGK BCPR6ES copper's on almost all the RB's that come thru the workshop as part of regular service. They're gapped at 1.1, although if you're running high boost then you'd probably want to go down to a 0.8

Also you can get different sparks if you're having troubles with a cold engine etc, but in general BCPR6ES's are the ones I use... coppers are great if you have the time and patience to learn how to change your own sparks... takes about 20 mins.

[TTT]

takes about 20 mins.

not the first time it didn't.. lol...

[funkymonkey]

true, but if you have coppers its something you do every few months, so you'd get used to it.

copper ngks are the way to go iridems ect ect we put in the back bank on v6 magnas and camrys cause there a prick to get to. 60 bucks a plug your paying for wank value and bragging rights . i would spend my money on copper ngks and a set of indexing washer;s and still be plenty of bucks in front .:-)

misfire under load with 2 sets of iridiums even @ .6 gap,went to copper plugs and wow no misfire and the iriduims always looked black and sootie,but the ngk coppers looked light and like they where burning well.
