from the MSP Aftermarket Guide:
SPARK PLUGS
Stock MSP spark plugs are platinum NGK PZFR6F's. Colder, copper spark plugs would be a wise investment if you're upping the boost in your MSP. Detonation (Pre-ignition, where the air/fuel mix in the cylinder burns before being lit by the spark plug) WILL cause damage to the motor. Why copper? Platinum plugs have a sharp tip and don't conduct enough heat away to prevent detonation at boost levels higher than stock. A copper spark plug has a wider tip that conducts heat much better, and may prevent you from messing up your motor. The factory spark plug gap is 0.028" - 0.032".
Copper NGK BKR7E's (#6097) are cheap (around $2 each) and work well for our car. They are one heat range colder, and are bare copper plugs. You can have your local auto parts store (Pep Boys, Autozone, etc.) special order them for you, or get them from http://sparkplugs.com/more_info.asp?AAIA=&pid=3040 or http://store.summitracing.com/defau...ighlight=NGK+11

BKR7E suk, they are NOT extended reach like the stock spark plugs.
use ZFR7F-11.
here is a link:

$2.44 a piece.

Forget all those copper plugs! Get silver! Even better still: Get BRISK LGS Racing plugs! I just put 'em on yesterday and I just couldn't believe it! One word: (wow) Buttery smooth engine, better acceleration. Feels like there's more power. I was using NGK Iridiums and loved them and I was skeptical the Brisk could be better. But they are, big time!! (bowdown)
Because of their shape, no need to gap and no need to index. They are extended reach and have a 360 degree spark that is also very long. Silver is the BEST conductor of electricity. Great combustion!
The one I put in are stock heat range (they make all ranges), the no. is DOR15LGS

You need a set of 4 plugs
In Canada it is Prenco Engineering who sells them:
http://www.prencocorp.com
The online store is here (that's where I got mine. $63 CAD shipped, via DHL):
http://www.plugs.janmax.com
You can get them here too (I don't know much about this store):

In the US, this is the site but I don't know if you can order them online yet:

I found a supplier in Houston, TX at www.lightspeedperformance.cc I am inquiring now if they do mail orders.
Are these really worth the money, and DOR15LGS plugs, how do you know they are ok for our cars, i couldnt find our car under any of the listings? no gapping required?

On this site http://www.plugs.janmax.com they have a cross-reference tool for NGK to Brisk plugs.
There is no gapping because the way they are made (similar to the Bosch +4).
There is one thing to consider though: I've been testing them for 3 day now and I noticed some misfiring at idle, very occasional though. I was boosting at 7 psi. Now I've tried stock boost (mine is at 5-5.5 psi) and everything is OK, no misfiring (yet). I think that the gap is a bit too wide for higher than stock boost, at least with the LGS. But Brisk also makes a silver turbo plug that is good up to 2.4 bars! (35 psi!). So if I were boosting a bit, I would look at those instead.
Other than that, so far so good. I'm waiting a few more days before I do a visual inspection.

If you have a stock msp. Then stock plugs are the best.

yeah i thought the idea for upgraded plugs was for uping the boost?FlyinMSP said:

The stock plugs are better for stock applications.
Check your plugs, listen to what they are telling you. Climate changes, differences in gas quality, driving habits, overall condition of the engine play a part in what plugs are best suited for your engine.
I agree.
The NGK Iridiums I had previously have been A1 in that respect. I'm waiting a couple more days b/f I check the Bisks and see how they are doing...
I like to try different things, to optimize and all. Spark plugs are quite cheap compared to othe stuff and the results can surprise sometimes. About the Brisk, I don't like the misfiring at idle (will prolly end up fouling the plugs), but they really rip under engine load!
