Dear All,
Does anyone know where I can buy Silverstone spark plugs for a Vauxhall Vectra (W reg 2.0ltr GLS, 16v, EcoTec),

But personally I would just buy the plugs from your local Vauxhall dealer, or through autovaux.

I like the "up to 137% more power" - very precise!

By heck! How can that be besides having 3/4 plugs not firing at all and the other one firing intermittantly?!

Very cleverly worded advert. Read it again. 137% more spark power. Engine power is much the same.

i noticed that they say silver is the best conductor known to man , why then do all the best hi-fi systems use gold on their connectors if silver is better, cant be for cost as silver is an awful lot cheaper than gold. i would stick with OE personally...cheers...keo.

They're quite right, silver's resistivity is lower than gold and copper, thus making it a better conductor! Didn't know that some HiFis used gold, and if they did, they would be better off using silver or copper as theyre both better conductors of electricity than gold.
|
>>Didn't know that some HiFis used gold
Gold plated connectors yes.Most Hi Fi systems of medium to high grade use oxygen free copper cable..top of the range may use silver cables..On a spark plug.. I feel that is well and truly over the top.I am surprised the plug has been designed in this manner.No doubt someone will explain the benefits of its use

Oxygen free copper (speaker) cable benefits exist only in the imaginations of the writers in the high fidelity journals and the like minded. As do the benefits of standing your speakers on cones. But as this is off-topic, for spark plugs, any further discussion will need to be under some other heading. Especially as the fanatics will defend their use of them to the death.

>>any further discussion will need to be under some other heading.
None in mind?
>>But as this is off-topic,
Same thing applies to Hi Fi in cars..So as Hi Fi`s can be installed in cars,So can a spark plug.Whether its of benefit is another matter.My point was- I didnt see the point..Get my drift?

Wrong! I'm not a fanatic but an engineer and hi-fi enthusiast. Oxygen free copper does what it says on the tin. If you have several grands worth of hi-fi you don't connect it up with bell wire!
Secondly, standing speakers on "cones" or more precisely 'spikes' serves to isolate the speaker and the benefits are certainly not imaginary. Stick to commenting on something you know more about please.

Here we go again. Sorry, you were wrong about the throttle and you are wrong about this.
What happened with hi fi journals, somewhere in sixties IIRC, is their 'experts' decided they had sufficiently golden ears that they did not need double blind tests, which is the only way to decide what is better or different.
Whereas the real experts were still doing it that way and were technically better qualified.
Just look at who has the audio patents. They have done more for high quality than any amount of hi fi journals. Just look at how Quad test for distortion on their amplifiers (if they are still going).
The hi fi 'experts' argued they had been doing reviews for years, many more than anyone else and so, how dare anyone criticise their opinion. Just like you are doing with mine.
Because they controlled what went into the journals, these 'experts' got themselves 'consultants' jobs from the amplifier companies. Those companies could not afford to have their amplifiers badly reviewed and lose a lot of business. It was not that the amplifier companies needed their expertise.
Because this literature was all that was available to the general public, a whole lot of misconceptions have arisen. 'You must avoid copper wire that has myriads of rectifying junctions in the copper'. Junctions? A complete load of tosh.
I am not suggesting you connect speakers with bell wire. If you have 4 ohms speakers (or whatever) you need wire that is a fraction of this in resistance. 10% or less is adequate. And, ideally, it should be in the form of a flat twin construction.
|
One final word on the claim that ordinary copper wire distorts audio frequency electrical signals. Attempts to measure it in 1988 failed with equipment that could measure distortion as low as 0.01% on a 200 microvolt signal.
There is no valid technical reason why ordinary copper wire should distort the signal.

>>But as this is off-topic,
So now who is going off-Topic..I presume you had to have the last word irrelevent or not!

My off-topic comment was about ME being off topic, not you. I just don't like people wasting their money as a result of being given duff info.

>>My off-topic comment was about ME being off topic, not you. I just don't like people wasting their money as a result of being given duff info.
So You can be off topic,but no one else can.
Its up to the people that buy these components as to whether they work or not..If duff info given and is noticed by the people that buy them.They wont buy anymore. and not recommend to others.If they work and is recommended by these buyers to other people they will buy..In Hi Fi terms who are you to tell others they are wasting money??

OK guys, you've both said what you've wanted to say. Lets leave it up to the people as to whether they want to buy such products or not.

Sorry DD. Only just seen your comment. Contributions ended herewith.

If you are happy in your world buying snake oil. Carry on. I don't contribute to HJ soley for your benifit. I don't ridicule you for your lack of ability to understand technical subjects. Why do you feel the need to have go at those that do. We live in a world of technology. It is no use denying it. It won't go away by kidding yourself it does not exist. There are plenty of well educated other persons who read HJ and will be able to understand the subject matter and learn from it. They have and do also make useful technical contributions that I have appreciated. Your attitude contributes nothing positivie.
|
Que? Throttle? You've lost me.
As for the rest of your posting it is just an opinion mate. It isn't rocket science to understand that if you isolate a speaker and other hi-fi components distortion will be reduced. If my speakers just sat on the floor then with increased volume the cd player and turntable would skip. FACT!!

I would guess that the gold (plated or coated) does not oxidise as readily as silver hence its use for connectors.
If the the electrodes are actually made of silver I guess that the reduced resistance makes absolutely NO difference to the spark from a conductivity perspective. Heat conduction may be improved however.
Snake oil!

Gold is used because it doesn't oxidise (silver does, a little bit).
If you want a good plug then go for NGK's - pref. the Iridiums.
|
|
So they promote the resistance of silver but VX use carbon leads at 1000 ohms per foot to be compliant with the EMC RFI specs. I would not waste your money my friend. I prefer Tri tipped Bosch or NKG's Regards Peter
