The best spark plugs on the market. This is the plug I use and let me tell you it makes all the difference.

Dyno Testing Videos

Call Tom at Light Speed Performance (713.896.0577) he keeps them in stock and has a plug for any application. If not he will get it in a day or two. Give Tom the NGK plug # and he will get you the Brisk plug that matches. Also please post any questions about the plugs and I will relay them to the Brisk Rep.

What application would I need for a high hp 350Z? As in, what would the p/n be and how much would it be for a set of 6?

I would have to assume this is a turboed car. Makes a big difference as to what plugs you go with.

Brandon@Forged

Yes, turbo.

Are these plugs only for FI and Nitrous applications or can they be used NA?

They have plugs for any application. NA, Turbo, and Nitrous. And for cars, trucks, and bikes.

I just watched that whole 18 minute video and those numbers they are getting are crazy. Up to 30 lb-ft torque more and 20 rwhp more from just the one step colder plug. It sounds too good to be true, but it is hard to argue with the proof shown in the video. Craziness.

Hard to believe it . Would like to see some one get these and do a before and after dyno

I know Light Speed has done some before and after dynos. I will see if I can get the info from them.

Brandon@Forged

As I mentioned, turbo'd.

I will ask Tom at Light speed for the part number of a plug that will be good for a turbo car making 500whp. I will let you know tomorrow.

Brandon@Forged

Thanks. Do you know if I would need different plugs for higher hp? I was planning on doing three maps: 530 - 550 on 93 octane, 650 on 93 octane, 750 on race gas.

hmm a test on a mustang? hmmm

NGK works well with imports but may not work well with others. Just like bosch plugs work best with european cars. and maybe this brand works best with american cars.

also, were both brands BRAND NEW when they tested it?

I can't even read the numbers on the dyno sheet since it's such a bad quality video.

for me, I would need to see results from people that bought it for the 350z instead of the shop that sells this plug.

Brandon@Forged

I've never seen a tip design like that, looks pretty cool. As far as the video, at least you can watch it, everytime I hit play it shuts down whatever program it is playing in (Internet explorer, AOL).

I heard of these plugs - I had heard that they're great when they are new and working, but they tend to be more prone to the tip breaking off leading to potential engine damage.

Not trying to knock the product, just heard there are cons that go with the pros.

If the original plugs were old or fouled, you will gain massive power on the dyno. I swapped plugs (and also a plenum), and made some serious increases...about 30-40 across the board.

McDuck also changed fouled plugs and noticed a very big gain on the butt dyno.

I am not trying to poo poo on anyone's parade, but I am always skeptical of very high HP gain claims with sparkplugs. In practicle situations, you just rarely see it.

I'd like to see a back to back with brand new NGK's 1 step colder vs. these brisk plugs...and on a dynojet so the numbers cant be manipulated as readily.

Sorry, the skeptic is getting the best of me tonight.

a 500rwhp or so Supercharged '03 Cobra tested these on my dyno and found no gains. Thats the only time I seen these in use.

mcduck

what GQ said above... replace the current 1 step colder plugs with NGKs (or something else someone is using now), dyno, put in these Brisk plugs, dyno, then compare results.

I don't think I got more power when I put my new plugs in. I think my old plugs had just worn enough that it had degraded over time and the new plugs put me back to where I started. Same thing probably happened here.
