brisk racing plugs

has anyone used brisk racing plugs and do they really perform as advertised

Racing plugs are, typically, a much cooler heat range than stock (note the number 12, instead of 8). Unless you are constantly running 8K to 9K rpm, you are not going to be happy. As a matter of fact, even if you are running at that rpm range, that is a big heat range difference.

Agreed...... these are waaaaaay too much money, plus you not likely to notice any performance increase of their claimed "horsepower" increase or fuel efficiency. It's all good in theory and OK for the purist, but you can run standard plugs or perhaps iridiums (which will last longer) at much less cost. You'll end up changing them at a shorter interval anyway, because spark plugs do break down over time. Interesting they say 20,000 mile..... not worth it.

PHD --

Brisk brags about these plugs producing 3 sparks per impulse. Problem one is that the energy delivered to the plug remains the same so that energy is divided down three times producing weaker sparks.

Problem two, only one spark at a time can be initiated so there will be three weaker sparks delivered in succession instead of one highly energetic and hot spark.

Problem three is a question; is your FJR suffering from ignition misfiring? If it is not misfiring, there is nothing to fix. Once the fuel charge is ignited the flame front is self sustaining in the FJR's cylinder head. There are some cylinder head/piston combinations and massive nitro-methane charges that may quench the flame front, but the FJR's cylinder head definitely is not one.

There is basically no plug that works any better than the NGK/CR8E, DESO/U24ESR-N. An iridium plug does not work better, it is just made with tougher materials that last a bit longer.

A spark plug with ("made with tougher materials") electrodes that don't erode as quickly (select/expensive metals) may work better -- over time?

There always seems to be a new wrinkle coming along for spark plugs? Sandia Labs. "E3" has been one of the more recent (a neighbor offered an unsolicited endorsement of "E3s" recently).

The BRISK patent reminds me of the 'surface gap' plugs of decades ago that needed a mongo ignition source to fire them -- but were OEM from some manufacturers.

Words and terms sometimes vary between different fields. In my field, when something retains quality over time it is referred to as reliable. To split very small hairs, I would say that the iridium plug has better long term reliability over a conventional plug.

When new and fresh from the box, an iridium plug is not better than a regular plug because the center electrode is not quite as conductive as a standard plug but the differences would only show up in a controlled lab test. Both the conventional and iridium plug would work virtually equally well initially; over time the iridium plug would continue to deliver more spark energy over a worn conventional plug. Technically, a plug isn't really bad until it starts to cause misfire. Practically, with fresh plugs the coil's job is easier and the spark energy is higher so flame front ignition occurs as early as possible.

Dare I say this is edging its way to NEPRT?
