I read that one of the options for a Black Top SR is to use NGK Iridium Spark plugs BRK7EIX. I thought that was the plug I ordered but I got home and noticed that they gave me the wrong plugs. The gave me BRK6EIX. I am assuming that these have a "6" heat range - meaning a hotter plug?
I will be running stock boost for now with all the normal mods for a swap. Will these plugs do the trick? Or should I return for the 7's? WHat are the drawbacks about using a "hotter" plug?
Thanks
Spark Plug ?
You'll be fine if you are staying stock. and yes the 6 in NGK part numbers indicate heat range. Heat range 6 is stock for the engine. If you plan on upgrading in the future I'd have those returned to get the 7s...those plugs are pricey, I also just bought a set.
In your case no drawbacks, but later on (high boost pressure your driving; harder you drive its better to have the 7s) it can cause the plug to get too hot causing preignition/detonation or the plugs to melt. But it you are stuck in traffic a lot and don't see a whole lot of revs and high loading, the 6s should do you fine until a serious upgrade (the 7s will foul easier).

what type of upgrades are you talking about? For the next 6 - 9 months I will be running stock boost with they typical upgrades
FMICKoyo Rad.downpipe, test pipe, exhaust
This car is NOT my daily driver so it really only gets use on the weekends if it is nice.
I guess I'll just exchange 'em, still a couple of weeks away from completing the swap.

more like power upgrades, particularly if you start running more boost.
The only real way to tell, is buy a set of either heat range and then read them after driving "normally" (ie like you normally would drive the car) for a couple weeks. If they are fouled you need probably need hotter plugs. If they are clean you could try and step up to a colder one and see how that goes. If drivablity starts to dive, (misfiring, hesitation at low end) then go back to the hotter plug.

Get some Bosch F5DTC plugs. They are great plugs, made specifically for a turbo application (copper electrode, deeper insulation jacket, .028 gap, etc). Porsche uses them OEM in their turbo cars. I had to order mine from Bosch, because the local parts stores did not carry them.
