Brisk Premium Performance Plug

[Vtim]

this is the standard 2 legged copper plugs from Denso

[Garlic]

Are there any benefits of such a design or is it just plain marketing gimmick?

[Genie47]

Eh? www.sparkplugs.com is selling gold-palladium plugs for USD3.40 only! Cheaper than platinum and iridium!

[Genie47]

The issue is that they seem to interfere with the gas flow.

[Colin03]

I am looking for IK22 and VK22.

 

Or any others that can be use on forester 2.0 .

 

Thank you .

[Genie47]

The materials are cheap since there is no platinum, iridium or gold-palladium. Electricity takes the path of least resistance. So there might be a 0.0000001mm difference that our gapping tools do not measure but the electricity going to jump the gap knows which is nearer so it goes for that one.

 

So it keeps firing and firing and firing until that side gets worn and the gap become big and the electricity this time sees they other ground being nearer and it starts firing to that ground. It keeps doing this until it sees the other ground that it used before being nearer now so it fires to the other ....... and so forth.

 

Advantage? Longevity for a cheaper material cost but you can boast and rip of unsuspecting customers thinking both grounds fire at the same time. Charge higher price loh!

 

Then there is this thing about interfering with gas flow in the area. No proven studies yet though we know a lot about an expanding flame kernel for the single ground electrode. You have to go to NGK website to take a look. It is sort of one sided. The flame kernel expands outward to the area where there is no ground electrode. If you got two, it looks like a scenario where the gases cannot flow very well. Imagine if you have four.

 

Some engines suffer on these multiground plugs while some don't. You got to try them. I suggest using the Super 4s since they are cheaper to see if it works for your engine.

serious, gold ley! so cheap

 

What brand? how to find in that website?

[Vtim]

will PM you

[Cyberet]

my veh suffers poor fc with super 4, but works extremely well with the 2leg denso coppers..

 

too much of a good thing may not be great after all

Then use the Denso K20TRs then. They are cheaper too, right?

Didn't know I am talking to an expert in sparl plug. Too bad most performance plugs are useless to you now.

 

Since you ran into initial problem with natural gas and have to re-gap your plug, tell us why you didn't gap closer than necessary since all you need is any spark and probably not how long it has travelled?

 

p.s. the site you gave seems to affirm what I said earlier. Too bad your prolonged sparking doesn't find much relevnace with Alpha's Twin Spark.

 

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]

I don't claim to be one and I show the sources of my information. I dare say I stand on the shoulders of giants.

 

It's Alfa not Alpha and you better correct it before the serpernt's horde in MCF descends upon you.

super 4 cheaper

oh well... wheres vtim?

[Genie47]

Not the Super 4+ lah. The plain old Super 4.

I wonder if it will work with my MSD CDI

[Cyberet]

ya, the copper super 4 right?, its cheaper, got straight from distributor

Mispelling is sometimes intentional - to differentiate the surface engineer and those under-current engineers. Perhaps, who do you think will be disinterested in these?

 

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

 

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)?

 

Is this prolonged sparking - "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" "
