inark Posted October 24, 2003 Author Share Posted October 24, 2003 does anyone know if its a bad thing to only replace the 3 dead ones leaving the others in there? or is it best to replace all 6?

GTS-t VSPEC Posted October 24, 2003 Share Posted October 24, 2003 I'd replace them all. Are you sure it's not due to detonation though, that is what normally kills plugs. I ran platinums in my car, making over 400rwhp at 18psi and there were fine. I now run BCP7ES plugs, which seem to be working very well, and there much cheaper:D Link to comment https://www.sau.com.au/forums/topic/27763-3-reasons-not-to-buy-ngk-platinums/#findComment-580412 Share on other sites More sharing options...
Jay95R33 Posted October 24, 2003 Share Posted October 24, 2003 DAMN !! The only time I've seen that happen is when the engine was pining... What boost levels were you running?

predator Posted October 24, 2003 Share Posted October 24, 2003 yowch, hope those didn't snap off into the engine! i think the problem is more due to something else other than just the plugs though. coppers are fine.. i'm glad i didn't get sucked in.. $23 vs $120 Link to comment https://www.sau.com.au/forums/topic/27763-3-reasons-not-to-buy-ngk-platinums/#findComment-580434 Share on other sites More sharing options...
GTS-t VSPEC Posted October 24, 2003 Share Posted October 24, 2003 The bits are normally blown out of the exhaust ports, but may be worth having a leakdown test to make sure they didn't damage the cylinder walls. My guess is serious detonation on the road, have it checked out ASAP.

inark Posted October 24, 2003 Author Share Posted October 24, 2003 yeah it happend at calder... at first i was only running 10psi which ran a 14.08 then we decided to up it to about 13psi to get into the high 13s... this is where they melted down... 3/4 down the strip POP and black smoke... still ran a 15.4 after backing down the rest of the qtr haha nice one sam for now ive replaced them with another 3 platinums as the dipshit at autobarn didnt know what coppers to use and the only thing his book had was platinums... i only put the others in about 2 weeks ago so they are pretty much new... just took it around the block at 9psi hitting 8500rpm around the corners and had no apparent issues... will leave the boost at the level its on incase my guage isnt showing the proper boost levels (only have ableed valve so have to rely on the guage)... looks like its time to take it to the dyno and make sure the guage is accurate.

B-Man Posted October 24, 2003 Share Posted October 24, 2003 What happened to the rest of the plug ?? Did it just melt or did it go through the valve/exhaust/turbo etc - Nasty stuff ! I've seen other threads with other (Unigroup guys) saying that this has happened them numerous times with Iridium plus !!! Damn I'm not gonna let this happen in my new engine !!!

predator Posted October 24, 2003 Share Posted October 24, 2003 NGK BPR6ES - $23 for 6.. Repco.. don't let them ask you what car its for i'll they'll cry. Thats what i've got in mine. Extra heat rating might not go astray it looks like (7ES) if they have them.

puckish Posted October 24, 2003 Share Posted October 24, 2003 Hmmmm Looking at these plugs the mixture looks okay. No clogging soot or leaning out light tan colour. Looks like the piston is hitting the electrode ? If you look at the higher boost racing plugs they have the electrode way deep in the body of the plug and ewither side gap or small gap. These seem not to ? Link to comment https://www.sau.com.au/forums/topic/27763-3-reasons-not-to-buy-ngk-platinums/#findComment-580614 Share on other sites More sharing options...
inark Posted October 24, 2003 Author Share Posted October 24, 2003 gordon - thats not the code of the plugs that were in there b4... i thought i kept them so i could put them in if i had any trouble with the platinums... guess i didnt. this is the first time in over a year of having the car that this has happend... this is also the first time since owning the car ive changed the plugs... the last ones looked like they had been in their for a long time but still looked reasonably healthy. Ive run my car with 16psi without any issues on em... i think i might pop into BMT and put it on the dyno and check the boost levels cause i think my guage isnt working properly... oh well.. it was a costly mystery... probably one which i wont ever find out the actual cause.

West Posted October 24, 2003 Share Posted October 24, 2003 You could try N1 out Nark, they have some Nismo plugs there, might worth a try, after runing at Calder, might car now also sound a bit un-healthy as well.

inark Posted October 24, 2003 Author Share Posted October 24, 2003 yeah i think they have died in the arse again... after i put them in they ran fine... closed off the bleed valve so that it was running "stock" boost and gave it a nice run around the cheltenham rd area and now it sounds like a WRX (very bubbly and unstable.... not smooth like normal...) so more fun for me tomorow pulling everything apart and checking the plugs again. if they have died AGAIN im taking them back and demanding my money back because that is 9 plugs ive gone thru ($180) in less than a month which is bullshit considering this is the "recommended" plug according to them. coppers here i come!! (yet another $60)... think i might try the bosch super 4s out... no need to gap them then.

Busky2k Posted October 24, 2003 Share Posted October 24, 2003 Get the NGK BKR7E. I have a set of them in my car. Very good plugs! NGK Tech said they are a better choice than the BCPR7s because of the V-grooved electrode and also more suited to Nissan heads (something about grounding). Tho the BCPR are still not bad... The BKRs same price as the BCPRs aswell... And stay away from the bosch plugs. Stick with NGK. They make the best plugs in the world..

NismoR34 Posted October 25, 2003 Share Posted October 25, 2003 Just wondering what kind of GAP the plugs had? Have a read through the technical tips here http://www.ngkspark.com.au/ there is some VERY useful info about plugs, gapping, heat ranges etc. FYI, this site recommends Platinums as the standard factory plug for my car, not sure about 32's or 33's though. That site is better than www.ngk.com.au as this one doesnt have any skyline imports listed just the local 31's etc. Well worth a read through the tech tips if you wanna know a bit more about ignition / spark plugs etc. maybe add to sticky list Link to comment https://www.sau.com.au/forums/topic/27763-3-reasons-not-to-buy-ngk-platinums/#findComment-581042 Share on other sites More sharing options...
