Copper plugs are cheaper but need to be changed more often. Plugs with the heatrange of 7 should be good for boost levels of 25 and below. If you're running more than that, you should probably go for heatrange 8.

Id buy the BR7ES and the BPR7ES. Try them both and decide which you think your car runs better on.

BR7ES - Non Protruding Tip
BPR7ES - Protruding Tip

I used to run the BPR I then tried the BR and found the car to like non protruding a bit more. I wouldn't switch to 8's until you gobigger turbo

The 7's = Stock heat range
The 8's = A step colder
Incase your were confused

You can go to NAPA auto parts and get the NGK BPR7ES copper plugs. They are like 2 dollars each and work great.

I think my BPR's knock less than BR.. it may be subjective... but theory goes that the closer the spark to the center of the chamber (with projected/protruding design) — to ignite the mixture from the center — the better the results/burn. If it's burning from the middle the process should happen faster (good for power and knock prevention). Non-protruding/projected tips were designed for smaller clearance chambers to avoid the piston hitting the plug tip.
It's also thought that BR is a half step colder than BPR..
All above, FWIW...


Oh and this:

^ Thinking about it that does make a lot of sense. I did run the BPR's for a while like I said though the car seem to run a bit smoother from the BR's. This was on the stock heat range with full boltons.

Now I'm big turbo and switched to the 8's. I immediately just picked up the BR's as I ran them in the 7's.

I'm going to grab BPR8's and see if I can feel any difference good or bad from the BR8's. I'll put the car into various situations and log each (Not sure that I'll see anything).

I def see where the theory of the protruding tip should produce a more complete burn.

thanks for the help

There is another school of thought which contends that a protruded tip, such as that of the BPR's is more prone to preignite the air/fuel mixture than the BR's recessed tip is. In this scenario, the hot, glowing tip, protruding further down into the combustion chamber, auto-ignites the air/fuel mixture prematurely, before the piston reaches TDC on the compression stroke, and before the sparkplug fires.

You can also pick these plugs up at Pep Boys in Raynham or however you spell it. They had them in stock a couple weeks back when I got them.
