Anyone ever heard of these? I would like to change my spark plugs, as I have not changed them... ever, and I've had my car for almost 3 years. My car is lightly modded and probably has about 350hp. I've got a turbo back, high flow cat, cam gears, and a piggyback. I was thinking of getting BPR8 plugs. I think the HIX stand for iridium. Does anyone know anything about these? Thanks.

Save your money, stick with copper. BPR8ES.

Hmm... Is there a reason the iridiums are frowned upon? I read that that coppers wear out faster?

Thanks for your input.

Mainly the price is the reason. Coppers due tend to wear out faster, but they are very easy to change on our motors....Suby is another story. I personally change my plugs out after every oil change or every other oil change as normal maintenance. 4 coppers = 1 iridium basically.

It's not that they're frowned on, it's just "WE'RE CHEAP"!!

I always run the copper core plugs, just have to change them more often.

I run iridiums in all my stuff, I've found they do better against mis-fires as well, at least in my SR20DET they did better.
I think you need heat range 7 though, and HIX stand for iridium and you should be able to find them for about $40 a set.

Hmm, so far, from what I'm hearing, the iridiums last longer, handles mis-fires a little better, but cost a lot more. I'm assuming that they don't last long enough to offset the cost, vs getting the coppers more often?

Also, heat range 7 is how they come stock correct? For my particular setup, is the 7 range still ok, or should I go to 8?

Thanks for the info guys.

Stick with the 7 heat range.

you get a better spark with copper than iridium. Best conductivity is in this order: gold,copper,silver

Ok, sounds like the majority would go with the BPR7ES. I was hoping that the iridiums would be the same as the coppers, so I could do less maint, but I guess it's worth it. Thanks everyone for the help.

stick with heat range 7 for your application. "We" don't chose copper because "we're" cheap, "we" chose copper because they are the best conducting plugs, period!

Iridium will last longer no doubt, but copper will produce a better spark and more power.
