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.

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

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)

    • Absolute f*cking nightmare. I had to take breaks constantly, and I was always pissed off when I got home. The line split in Italy on day 2 (we drove from the Netherlands), lol. Driving any narrow European town was... well, sh*t.   Appreciate it man. Here, I'll just drop a favourite from the load I took on Saturday.   I'll update here when things happen with the car, the thing is, with stock power and almost everything chassis-wise taken care of, there really are no problems. 268,000kms now and counting.  
    • Ah! I actually managed to snag a lightly used set.... that aren't so suitable for me right now. They don't work on a GTT without some cutting or creative heat moulding. I thought about reselling them myself cause I didn't want to murder them, but it looks like I'm probably going to attempt to murder them/melt them because I may as well. @GTSBoy @PranK can somebody close this thread?
    • Hey mate,  I have a set, one is slightly damaged but wont be noticable once installed.  Shoot me a message if your still after them 
    • I couldn't wait But, the black constant tension hose clamps were too thick and there wasn't enough clearance at the T/B and I couldn't get it to seat properly, so I had use a silver one there I also added some 3" silicone over the alloy bit that goes through to hole on the radiator support as it looked like it was sitting on the edge of the hole in the radiator support, I never noticed a rattle or anything, but there was a witness mark It is basicly done, and I can live with the silver hose clamp at the T/B, I will get a black clamp for the head vent though where it is attached to the bulkhead fitting  It never stops...LOL, only issue now with the shock tower brace is it slightly touches the under bonnet liner now, if I leave it it will either wear some paint off the brace where it touches, or damage the liner, so I removed the liner to see what I have to work with, with the liner removed I have about 20mm of clearance, but sadly the middle part of the underside of the bonnet is only dusted with paint and looks crap, so I cannot have that, but.... as I have a roll of Carbuilders premium under bonnet insulation in the garage laying around that is only 5.5mm thick (we were going to use it on the boys Patrol, but he crashed the front of it a few months and it was written off, hence why he now drives my old Honda Accord Euro), I'll use the OEM liner as a template and get the Carbuilders stuff fitted up to cover that dusted paint up
