BRISK PREMIUM LGS SPARK PLUGS

http://www.brisk.cz/en/pro1c.php



any chance anyone has even heard about these or know where they can be had in the usa???

I really like the idea of the holes in the side so fuel can flow through and the 360 spark is neat. lets it go in any direction but still with plenty of sharp edges.







Unique patented spark-plugs


Completely new spark-gap shape
Higher output
Better acceleration
Better fuel energy utilization
Spark gap is extremely deep in the engine's combustion chamber
Slide spark with maximum length (almost 3mm)
Integrated side electrode that improves heat removal from the active part of the spark-plug and provides optimum function.


Ionisation and spark-over occurs automatically together with an optimum composition of the fuel/air mixture. The spark gap is not shielded by the side electrode, so the mixture has unlimited access. Better mixture ignition, and thus higher combustion speed, and faster flame front spread, especially at the beginning of combustion, allows better fuel energy utilization. The subsequent increase in medium effective pressure in the engine cylinder and balancing of values of medium effective pressure during individual working cycles contribute to increased engine power.

this place has them but 1o bucks each and in Canada.

looks like a waste of money to me. and that picture that shows the 'purple' spark coming from all around is total .. they just seem crappy to me but i guess they are the same as the Bosch 4's. just looks like they would foul to easily. but that is just my opinion..

looks like complete BS to me...stick with regular old AC Delcos and you'll be all set.

I just think that all those "special" spark plugs are crap. unless you have a realy high tech engine, like a BMW or Mercedes or something.

brisk is a very old company use to be called PAL, they had a super Pal plug that would last years without being replced. this is there new top of the line plug.

Another interesting spark plug company.
Personally spark is spark. The major factors are voltage and current (depending on resistance). No matter what you change in the engine, there will only be one path of least resistance and that is the path the voltage will take to ground. The best thing you can do is index the spark plugs and gap them as wide as possible without mis-fire around redline. If you've got a crappy coil and high compression (more resistance in the chamber because of the compression) then gap smaller. If you haven't changed anything, gap larger. Oh yeah, and the whole multispark MSD box's are also a lot of . If you understood that typical ignition systems keep voltage going accross the spark plug for a longer period of time at lower engine speeds then that whole "multi-fire" excuse is just that! CD is only good if you've got a real fire breather of a motor. Do you honestly think that the 60's muscle cars would have been faster with an MSD box, lol, I just laugh when I think about it and how often people mistaken bad plug wires, plugs, coils, etc. for needing an MSD 6 box.
I guess there will be people buying these things just like those that bid on ebay electronic turbo's.

FYI
Good Plugs.
$9.25 for good plugs is fine.
In Canada exclusive distr. for North America.
BMW riders used those plugs.
BMW RT discussion Board
Even MiniVan will fly if ignition system is healthy.

Thanks

I head about them on the VOC mailing list.

"When I was racing, I replaced my NGKs every race
without thinking twice about it. When I switched to PAL plugs, I
didn't change them for the next two years, but I think the company is out of business now."

Sorry Gumby,

I didn't get it. Which company is out of business now?
Brisk?
No. If so, then it's incorrect information. How far I know up and runing well.

BRISK Spark Plugs for "tuning and tuners"

Gumby

The guy thought pal was out of business, they kinda are as now they are called Brisk.

Gumby

I was just looking for some feed back on the brand, I really have no intentions to use them in my bird, but I may get a set for my bike.

Good for Bike and worse for Bird!
What's wrong with Car?
The plug has unusual design but actually made for "The engine of internal combustion"

Gumby

Nothing wrong with the car but that would cost a bit. I stay 3 bucks n under on plugs for the car.

The bike I have it tuned for once it heats up, being a twin and it has two cabrs betwen the cyls. once at operating temp it needs to be a tad richer from heat. Not a big deal or a problem but at startup it easy to foul out a plug.

Its also them Hitachi carbs, [not the best in my book]. The idle and pilot circut is a tricky, picky bastard that is the little gremlin that fouls out the plugs. The pilot circut has to be set rich so the transition from pilot 2 main jet is not embarsing once the bike is warm.

allowing fuel mixture into that part of the plug would more than likely promote fouling on a carbureted engine...and in extreme cases seems as if it would be prone to detonation
