I was in Halfords the other day looking at spark plugs and come across twin and quad sparks. It got me thinking, could you use a twin spark in a car that doesn't come standard with them?? If so, what are the advantages?? :/

 

Ive looking on the web and found that people say that it helps with ignition, igniting at 2 different times but that's all i can find! Any help will do :)

 

Thanks!

Not sure but looked into it before from what I remember there is no real difference in terms of how the car runs it just gives it a better chance of a reliable spark as there is more sparks but it will still only ignite once.

So can you use them in a car that doesn't come standard with them?? Dont wanna sound stupid or anything asking that. :/ haha

they can be used in any car, they just have a chance of giving a good spark.

 

the mixture only needs one spark to ignite and burn almost instantly, so no benefit from 2 sparks

Just pay attention to the heat range of the plugs. if the plug runs too hot you risk pre ignition and if it runs too cold it soots up. Other than that they are OK to run in any motor with a decent ignition system.
