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)

    • Was there ever a model of the Stagea m35 that didnt have a badge on the grill? I thought I saw that somewhere, some aero edition or something? I cant find it again? davemoto
    • Its a 2002 vr-x four VQ25DET, silver. Coil overs, lowered, polished alloys and sport exhaust. Bit of a project, was sitting in a shed for a while but runs and drives great.
    • I wasn’t able to replicate the sound anymore. It was a one time sound so maybe it was just coincidence but it was like small pebbles being dropped in a coke can.   should I try cleaning the MAF? It could be it’s functioning but dirty? I don’t know.
    • Update 4: Hi all. The car drives again! Haven't driven for long, only to store it in the garage again, but the test drive was successful. The coolant and oil leaks seem to be fixed for now. Temps on the engine were also very good, while moving I never even saw 80C water during the approx. 30 minute drive. Ate up all the coolant in the reservoir though so will have to fill that even more when I go to the car next time. One thing that pisses me off is that the RPM gauge is still f**ked, I even resoldered the board twice and used copper paste on the silly screws that are used as connections. Next time I take it out I'll take apart the board and fit new components, I'll see if I can get a replacement IC for it.  I have an appointment set for 22nd of September for the engine tune to 370hp. Alignment also still needs to be done. My hope is that I can get all the legal stuff over with by the end of this season. Anyone of you have advice regarding intercoolers? Currently there is an APEXI core fitted, one of those weird hybrid ones, 600x270x76. I don't think it's bad but it's not new and now I still have the chance to change it now to legally include it in the paperwork. Only issue is that the only options that would arrive in time are a HKS Type R intercooler or generic Ebay spec intercoolers comparable to a JustJap one. Ideally I'd order a Plazmaman but it takes over a month to receive which would mean making the car legal has to wait until next season. Would love to hear some input on this. Same story for my injectors, the previous owner was a nunce and put ID 1050x on the engine. They work but are obviously not ideal at "normal" power levels. But I don't see a reason to change them unless the tuner says it's necessary. I read online before buying a different exhaust that the top secret style rear diffusers won't fit due to the size of the rear resonators. My buddy and I made it work by slightly "adjusting the shape" of the mounting bracket and making some spacers out of 3d print for the mounting bolts. Fits like a charm. Just putting this here in case someone has this problem. Even the hefty HKS Silent Hi Power rear can fits without hitting anything.
