What Spark Plugs For R34gtt Neo ?

[BASHO]

Like the title, what spark plugs for R34GTT NEO ?

I've searched here, Denso and NGK and come up empty with plenty of info on plugs for everything else and the fact that some owners change the plugs either at service time or because the have a slight miss only to have the coil packs shit themselves 5 minutes later.

So please if you know post what --or a link--

seriously, learn how to search. this topic gets covered nearly everyday. the NGK website will even put up a part number for both platinum and iridium plugs for the r34 (as well as all other skylines), and it isn't even in a hard to find place.

i would post up the part number for the copper plugs which i would recommend, but since it has already been covered so many times over the past week or 2 i think you need the practice to improve your searching skills.

Thanks for--well --SFA , if this topic is going up every day I would suggest that finding the answer is not quite straightforward .

The part No on NGK is not for the R34 GTT NEO the part Nos for NEOs only start in 03 /01 2 years after my car was made and is a much different part No than anything preceeding it.

If the copper plug part No that you have'nt wanted to give is BCPR6ES I have it and as to whether it's suitable or not is the information I don't have, however, I wouldn't be paying much attention to a know all frak all answer comming from you.

I shall in any event phone NGK and post the result perhaps it could be included in the service information for R34 GTTs where everyone can find it easily.

omfg ok if u want 2 be 100% shore take out the old ones and get a mate to drive u down to the local auto 1 that way u can be 100% shore ur getting the right part and u will also be able 2 see if u need a hotter or colder sparkplug done easy stop being a bitch

mad082 is on the money u should learn how to search

this is from a sticky in the forced induction thread. definitely worth a read. i went through the same thing myself recently with my gtt and posted what i did at the end. good luck

Thanks mighty for that it's a fair cow when theres no workshop manual available and the service manual assumes that you will automaticly just 'know' stuff like what spark plugs.

i don't think you were reading the right thing. i think you just saw NEO and then didn't read what followed it. the NEO listed on the NGK parts finder is a VQ25DD (which is the V6 from a v35 skyline). had you looked at the one above that that said

5/98 - 6/01 Nissan Skyline 2500 Turbo RB25DET

then you would've found the right part number.

as for the BCPR6ES being suitable or not, well considering that probably atleast half of the skylines on this forum are running it, or a variation of it, then i would say yes, it is suitable

This does not specify this is suitable for the NEO engine yet the latter for the Vs do therefore you assume this is the right one along with the assumption that the BCPR6ES is good just because it's commonly used.

The sight is littered with post of vehicles with missing and ignition problems usualy coil and plug related.

If you can't see a possible correlation between correct plugs and potential problems thats fine.

For me--well-- near enough just aint good enough.

And you still didn't answer the post topic--brilliant--

[mad082]

99% of missfire issues is caused by old and worn coils and not the spark plugs, and you will find that if you talk to anyone who has fitted new coils that their car runs brilliantly. the people who are changing their plugs and then having the coils shit themselves 5 mins later, the coils letting go weren't because of changing the plugs. they changed the plugs because the coils were starting to shit themselves and they were just hoping they might be able to bandaid the problem with new plugs. but then after a little while the coilpacks get worse and they are forced to replace them. or they way that they have handled the coils has made the problem worse, in the same way that picking up a glass with a crack in it may make it fall apart.

as for the year model not specifying it being a NEO, considering that ALL of the RB motors in that age were NEO motors, it's pretty safe to assume that they have taken that into consideration as there weren't any massive changed between the NEO engines and the non neo engines.

saying that just because the plugs are used commonly doesn't mean that they are right is pretty stupid. half of the code of the part numbers of spark plugs refers to the physical properties of the plug, such as the thread size. so lets take the codes for both the copper plug and the iridium and look at them.

first, the copper. BCPR6ES. the BC means that the threaded section has a diameter of 14mm. this means that any copper plug starting with A, C, D, E or DC won't fit as the thread will be a different diameter so it either won't screw in or will just slide in and out. then there is the E after the 6. this means that the threaded section is 19mm long. so this determines how far down into the cylinder the plug goes. too short and you won't get very good combustion. too long and you may damage the pulg. using this info you can see that you can use either a BC plug or a BK plug as the lower dimensions are the same. all that varies is the top half as the BC plug is a taller plug so makes better contact with the coil.

now lets look at the iridium plug. BKR6EIX. again the BK tells us that it is a 14mm plug. the E tells us that the thread is 19mm long. the remaining letters and numbers tell us the heat range (in the case of both plugs, they are heat range 6), the R says it is a resistor type plug (which they both are). resistor type plugs have a resistor built in to reduce electromagnetic interference which can effect sounds systems, phones and even the ECU signals. the IX tells us it's an iridium plug. in the case of the copper plug the S says it is a standard plug. and the P in the copper plug refers to the shape of the insulator.

so using that info you can work out that the BCPR6ES copper plug, the BKR6EIX iridium plug and the other common copper plug BKR6ES are all the same dimensions where it counts, just that the BCPR6ES plug sits out of the top of the head a bit more, which isn't a bad thing.

so i think it's time for you to grow a pair and stop being a whiney little bitch and see that the advice i am giving is accurate, and that the BCPR6ES plug is a plug that is commonly used because it works, and any problems arrising with coils after changing plugs wasn't caused by the plugs, but by the fact that the coils were dying to start with and they changed the plugs hoping that it would go away. a good analogy would be someone with a vibration through the steering wheel when they put the brakes on. getting a wheel alignment and balance may help with the problem (more than likely not though), but if the rotors are warped the only way to properly fix it is to get new rotors.

The rest of your appoplectic rantings I don't realy give a rats ass about , I've already told you anything you might have to post is irrelevant as far as I'm concerned you're a ffff---uckwit.

However the above insult is-well- an insult and warrants a response.

I realy shouln't be bothered but with nothing better to do ATM and out of sympathy I feel obliged to point out that you obviously know nothing about "having a pair" as you obviously sit down to piss, you also undoubtably think that accuracy is irrelevant and prefer to refer to hypothosis as fact, I sumise that you are probably also a lifetime subscriber to Hot Fours.

You obviously have the right of reply , if you mum will let you of course. I await with baited breath for the next deluge.

Just FYI----I phoned NGK---and I'm still waiting for an answer.

[mad082]

you can think what you want. you obviously don't want to take good advice and would rather sit around sucking your mumma's tit until someone hands you the answer on a silver platter, in which case unless they can give you a garantee from the nissan engineers who designed the RB engine you won't believe them either. if you are so worried about spark plugs, why don't you just go buy some from nissan. you may as well leave the forum as pretty much all the advice on here isn't going to meet your astronomical expectations, since it is all tried and true methods, and things that have been proven to work still but won't satisfy your questions.

but hey, you're right. what would i know? i've only but the BCPR6ES plugs into a few different RB engines and never had problems with coil packs, and neither would any of the hundreds, or even thousands of other people running these plugs, as well as the large number of tuners who would also be using these plugs in cars they have worked on.

spark plugs are extremely simple items and work off a very simple principle. as long as the heat range is correct (or close enough), the thread is the right size and they are tall enough to contact the coil, then it doesn't even matter what material they are made out of. infact you would run 3 copper plugs, 2 iridiums and a plantium all in 1 engine, and you could have all 3 different temp ranges and they will still all work fine. it would be no different to having the tyres on the front of your car different to the ones on the back.

this is what i use in my 34;

BKR6E (0.8mm)

or

BCPR6E (0.8mm)

BCPR6E (1.1mm if you're running stock everything)

Cheers for a straight forward answer,

It aint my mothers tit I'm sucking on----- and I always heed good advice-- when I get it .
