Car question:


Whats an equivalent spark plug for BCPR7ES or something that is a decent copper plug that can suit up to 400rwkw (including 400kw).

And can I buy them off a shelf.
If so, where. All info seems to have disappeared about 2012 re: Spark plugs and none of this stuff is on shelves anymore and I want to buy them on the weekend, in Melbourne.

Bkr7e but try R and E auto parts on centre rd springvale. Next door to repco. They usually have stock of bcpr7es. If you get stuck I have a set of 6 that I've only used for 50km. Replaced them chasing a misfire that turned out to be something else.
  • Like 1

I have some iridium 8's that were $75 a plug and were scheduled to last a lifetime. They haven't given me an issue but I do get misfires at 20psi (380+kw).

So I thought to stop using amazing super plugs, and wanted a basic plug that is known to work, as its cheaper to try that first than replace Splitfires (which are now getting on in age, almost 10 years).

I got a misfire at idle that went away, and I'd like to have plugs in my hand ready to go should they be needed instead of looking ages later when I have a car running on 2cyl or some shit.

I was using bcpr7es plugs at 394rwkw.
So I would just get those.

Guess I'm headed to RE Autoparts then!

They seem harder to find than most, these plugs, figured people would have found some other alternative on a shelf. Good to know the BKR7E is usable if in a pinch

I get my BKR8's from Springvale Autobarn. or Bursons. i cant rememeber. I got a box of em.

Everyone stocks 6 heat range but not many have 7. Greg also give bursons a call if r and e has no stock. So are you planning a track day this weekend ?

Nope, just had misfires at 20psi and a random one at idle today so wanted to have something on standby.
$80 plugs you use "forever" I don't trust to actually last forever :P

Nothing lasts forever, especially plugs. I got sucked into iridium's once, never again on a modified car. Copper for life. Like birds, I buy them in bulk. Last couple of times through spares box, where about $4 each and free delivery on overs over $50.

How the f**k did you research plugs on SAU and then buy iridiums expecting them to last?

There has to be at least a hundred threads telling you not to bother and just use BCPR7ES

Iridiums aren't a total scam per se, they do last for many times longer than normal plugs do...but the assumption made by the marketing claim is that they aren't going into a high performance car. A daily driver can use iridiums and will probably not notice a degradation after 50,000km etc. because performance decreases aren't as obvious nor are the plugs performing in an extreme environment. Iridiums wear like copper plugs do, but will retain say 70-80% of their performance after 10,000km, unlike the latter. This is useless in a high performance environment where you want plugs to be delivering 95%+ and as Iridiums can't do that any better than copper, better off saving your money.

I didn't research here. I spoke to Trent @ Chequered while my car was literally being tuned, and asked him what plugs to recommend for my setup at the time, taking in account my timing, ease of change, desire to not have it blow out and for it to last forever.

What he recommended did just that, I never had spark issues until I took a lot of timing away, and took a lot of boost away.

So I was asking on a more common setup, which is closer to what I have now, and the BCPR7ES work really quite fine, no misfires at all and I'm really happy with that, and really not that hard to change or check. The old plugs really were going strong but not suited to what I am doing now (they were also too cold a range, looking at them out of the car)

    • OK, so regardless of whether you did Step 1 - Spill Step 2 - Trans pan removal Step 3 - TCM removal we are on to the clean and refill. First, have a good look at the oil pan. While you might see dirty oil and some carbony build up (I did), what you don't want to see is any metal particles on the magnets, or sparkles in the oil (thankfully not). Give it all a good clean, particularly the magnets, and put the new gasket on if you have one (or, just cross your fingers)
    • One other thing to mention from my car before we reassemble and refill. Per that earlier diagram,   There should be 2x B length (40mm) and 6x C length (54mm). So I had incorrectly removed one extra bolt, which I assume was 40mm, but even so I have 4x B and 5x C.  Either, the factory made an assembly error (very unlikely), or someone had been in there before me. I vote for the latter because the TCM part number doesn't match my build date, I suspect the TCM was changed under warranty. This indeed led to much unbolting, rebolting, checking, measuring and swearing under the car.... In the end I left out 1x B bolt and put in a 54mm M6 bolt I already had to make sure it was all correct
    • A couple of notes about the TCM. Firstly, it is integrated into the valve body. If you need to replace the TCM for any reason you are following the procedure above The seppos say these fail all the time. I haven't seen or heard of one on here or locally, but that doesn't mean it can't happen. Finally, Ecutek are now offering tuning for the 7 speed TCM. It is basically like ECU tuning in that you have to buy a license for the computer, and then known parameters can be reset. This is all very new and at the moment they are focussing on more aggressive gear holding in sports or sports+ mode, 2 gear launches for drag racing etc. It doesn't seem to affect shift speed like you can on some transmissions. Importantly for me, by having controllable shift points you can now raise the shift point as well as the ECU rev limit, together allowing it to rev a little higher when that is useful. In manual mode, my car shifts up automatically regardless of what I do which is good (because I don't have to worry about it) but bad (because I can't choose to rev a little higher when convenient).  TCMs can only be tuned from late 2016 onwards, and mine is apparently not one of those although the car build date was August 2016 (presumably a batch of ADM cars were done together, so this will probably be the situation for most ADM cars). No idea about JDM cars, and I'm looking into importing a later model valve body I can swap in. This is the top of my TCM A couple of numbers but no part number. Amayama can't find my specific car but it does say the following for Asia-RHD (interestingly, all out of stock....): So it looks like programable TCM are probably post September 2018 for "Asia RHD". When I read my part number out from Ecutek it was 31705-75X6D which did not match Amayama for my build date (Aug-2016)
    • OK, Step 3, if you need to remove the valve body, either to replace it, the TCM, or to do a more complete drain.  First, you need to disconnect the TCM input wires, they are about half way up the transmission on the drivers side. One plug and the wires are out of the way, but there is also a spring clip that stops the socket from sliding back into the transmission. On my car the spring clip was easy to get, but the socket was really stuck in the o-ring of the transmission housing and took some.....persuasion. You can see both the plug to remove (first) and the spring clip (second) in this pic Incidentally, right next to the plug, you can see where the casting has allowance for a dispstick/filler which Nissan decided not to provide. there is a cap held on with a 6mm head bolt that you can remove to overfill it (AMS recommend a 1.5l overfill). Final step before the big mess, remove the speed sensor that is clipped to the valve body at the rear of the box.  Then removal of the Valve Body. For this the USDM Q50 workshop manual has a critical diagram: There are a billion bolts visible. Almost all of them do not need to be removed, just the 14 shown on the diagram. Even so, I both removed one extra, and didn't check which length bolt came from which location (more on that later....). Again it is worth undoing the 4 corners first, but leaving them a couple of turns in to hold the unit up....gravity is not your friend here and trans oil will be going everywhere. Once the corners are loose but still in remove all the other 10 bolts, then hold the valve body up with 1 hand while removing the final 4. Then, everything just comes free easily, or like in my case you start swearing because that plug is stuck in the casing. Done, the valve body and TCM are out
    • OK, so if you are either going for the bigger fluid change or are changing the valve body which includes the Transmission Control Module (TCM), first you should have both a new gasket 31397-1XJ0A and a torque wrench that can work down to 8Nm (very low, probably a 1/4 drive one). You can probably get by without either, but I really didn't want to pull it all apart together due to a leak. First, you now need that big oil pan. The transmission pan is 450 long x 350 wide, and it will probably leak on all sides, so get ready for a mess. There are 24x 6mm headed bolts holding the pan on. I undid the 2 rear corners, then screwed those bolts back in a couple of turns to let the pan go low at that end, then removed all the middle bolts on each side. Then, undo the front corner bolts slowly while holding the pan up, and 80% of the fluid will head out the rear. From there, remove the remaining bolts and the pan is off. You can see it is still dripping oil absolutely everywhere...it dripped all night.... I got another couple of litres when I removed the pan, and then another few when I removed the valve body - all up another 4l on top of the 3 already dropped in step 1.
