Brisk Premium Performance Plug

[Genie47]

Champion is made by Federal-Mogul group in the US. Pretty much standard plugs supplied to their shops. Pretty run of the mill stuff as with their Autolite brand also from FM that targets the performance market.

Well from the first thread, intent has been to hear out the experience of the users of Brisk LGS. Your case is probably a incorrect choise than a problem of LGS.

 

Almost all users complemented the noticeable improved improvement. Initial downside has been the unreasonably prohibitive local prices (found out overseas prices lower than SGD110 incl shipping). 30000km life is unavoidable if talking of true high energy ignition and not just lower firing voltage of iridium or platinum. But again still good value if compare to the extra $15 on engine oil that serves no noticeable performance improvement.

 

Let's see if there are any genuine cases of bad experience.

[Genie47]

The fuel mixture in the combustion chamber either ignites or it doesn't (resulting in backfire). Combustion energy does not depend on spark energy. Therefore greater horsepower does not come from greater spark power.

 

Everyone here would be in agreement that to get the car going, just get Densos or NGKs. Even lowly SGD2-4 normal BKR6E11 or K20PRU11s will do the job adequately.

What if power improvement is observable in the dyno with LGS, would you like the fund it?

[Genie47]

I won't because I don't want to buy them. I stay way from the "expensive = good" mantra. It ruins my life.

 

BTW, a bigger match causes the same size explosion as with a smaller match in a confined room provided if both the rooms are filled with the same amount of fuel-air mixture. You will not get a bigger explosion.

We are not talking about the usual 80%-90% of combustion but squeezing out the remaining power from the last 3-5% of non-combustion - this a single point spark across a copper gap is not the best in getting the job done I would think. Guess you are old enough to hear some people can smell your exhaust to tell the health of your ignition.

 

It is true that it takes only a spark to start a fire. But it needs a sustainable fire to start the burning going and it will never be possible without many simultaneous burnings to quickly clear a complete forest.

 

With this analogy, it might not be too difficult to understand probability of misfire in the context of higher vs lower firing voltage; difference in combustion propagation between exposed and obstructed ignition; and rate of combustion with respect to point ignition vs spread multiple ignition.

[Genie47]

Read above. Either the spark ignites or it doesn't. That's all a spark plug does. To scavenge the rest, you need a prolonged spark as you have said. These Brisk plugs do not prolong a spark.

 

For the normal car around. They just need the fuel-air mix to ignite. Nothing more.

MSD CDI will do a good job, I'm using the DIS-4, a older model now being replaced by the DIS-4 Plus http://www.msdignition.com/ignition_24_6211_6215.htm

 

now I just have to pay $2+ for a standard copper plugs

To clear out any doubt.

 

A surface discharge design doesn't mean multiple sparks simultaneously, the spark will only jump the gap to the lowest resistance ground.

[Hattee]

Which is better in burning away the last 3%-5% of fuel mix - instantaneous spread ignition facing the fuel-mix compression front or the prolonged ignition you now suggested (which is hidden behind an earth electrode)?

 

If I understand correctly from Twin Spark Alfa Romeo engine, the scavenging of unburnt fuel mix is either simultaneous sparking or an extra spark during the exhaust stroke. The spark plugs are symmetrically located in the upper part of the chamber to the sides of the line passing from the opposing intake and exhaust valves and this allows the usage of larger intake valves due to the missing central spark. Thus the 2L version of the 8V engine uses 44mm intake valve. By firing the spark plugs at the same time and considering their location the burning lasts shorter time (faster burn) because the mixture is ignited simultaneously from 2 different locations. This allows usage of less ignition advance than when using single spark ignition. The later 16v TS there are 4 independent 8-ampere coils, connected to plugs; 1a and 4a, 1b and 4b, 2a and 3a, 2b and 3b. This arrangement facilitates the separate firing of the spark plugs in each combustion chamber, and also saves parts by utilising a "wasted spark" system, where - between the exhaust and inlet stroke of each pistons "partner" - a useless spark serving more to improve emission than anything.

You cannot get past me for passing yourself as some ignition expert.

 

Next time, try to quote the source: http://en.wikipedia.org/wiki/Twin-spark

 

Too bad you replied to an Alfa enthusiast that does not own an Alfa.

 

Graduating from Google University and then obtaining a doctorate from Wikipedia will make you look like an expert in front of everyone in MCF but you are still plagiarizing. Hey man, the info is free might as well make use of it so that it makes me look good in this thread. I've seen some sneaky fella in Thailand do it at the war museum at Kanchanaburi before. Stole official Australian War Gravese information to pass on as his own in his tour group.

 

Engineers are not interested in burning away the last couple of percent. They just want to ignite the mix. Multiple spark discharge serves the purpose of have this free ignition advance should you have the tuning and fuel to take advantage of.

 

I would love to have an Alfa however, my car is more like an agricultural tractor moving groceries and kids. Ditto with many here. Ask them if they would love to have a SGD100+ set of plugs. I've seen double platinum plugs going for much less.

[Genie47]

And when one ground is worn to have a larger gap, the next unworn ground takes over and vice versa. VIOLA! Extended plug change intervals using cheaper materials!

[Smhomie]

Holy Moly-denum Ester!

 

You mean all this while I have been wasting my time with a faker who pretends?? This is very annoying for me to know after reading this posts... Thanks G for pointing this out in the open.

 

Now it all makes sense when you piece 2 and 2 together :

 

Thread about BORpower then argue, post about MyGreen Oil then argue and lastly post about Brisk LGS then pick an argument (with me).

 

But ALL 3 threads have been systematically shredded with him looking like Homer Simpson = "DOH!"

 

Wonder if he is thick-skinned to post again (on something else new now?)

oh yes, from $4 to $6 per plug, boy I should have taken the whole lot

[Garlic]

Thats cheap man .... for Toyota only?

 

I'm still having trouble getting 6 pieces of PLFR5A, they are very expensive and the local stockist only sells them in boxes of 4's.

 

Each piece is $25.

Is this considered a surface discharge design? http://www.boschautoparts.com/Products/Spa...gs/IrFusion.htm

 

 

Read in BITOG that there are some members having issues with Bosch Super4 due to the 4 ground electrode design.

[Trex101]

It's consider a semi-surface discharge.

Example look like this.

[Vtim]

It was a one time deal, one stockist is closing down and clearing all his goods at "jump building" prices

 

My friend bought over the lot of Double Plat from him, about 800+ plugs at very very good price and ask me if I am interested to take the whole lot, I was like

 

Ended up I only took about 20 plugs
