hi thanks i think i know cmng... haha .. hmm about the nology thingy ah some one actually have a story where it goes like this... try not to used too high density cable cause it will end up your engine not lasting if too high explosion it will cause a hole at your piston head eh... so how do or not do? confuse????????
heart breaking actually coz it is reasonable ma rite? what you guys think?
Melon,
it is a very debating topic about plug cable and plug causing the piston head to berlubang.
i ever heard that high performance plug cable (which is thick thick one, 9mm-12mm) can cause the piston to berlubang. i also heard iridium spark plug will cause your piston to berlubang or crack. well let us just think logically.
greater spark of course give you better combustion right? iridium spark plug give u better sparks for sure and why do u think this better spark will make your piston crack? is it that the sparks from the plug will shoot the piston head til it crack? NO!! piston head crack due to high temperature and high pressure! honda DSL engine have 2 sparks plug; at higher rpm the 2 sparks plug will fire at the SAME time!! dont think this 2 sparks plug will give u even BETTER SPARKS than 1 iridium plug! u ever heard honda DSL engine piston berlubang because it uses 2 sparks plug on 1 piston?? the answer is NO! a lot of people just think that greater sparks will make your engine hotter! then your piston will rosak! the ANSWER IS NO! better combustion will give you higher temperature (this is true). if your engine radiator is working fine then you need not to worry that your engine will overheat and cause the piston to crack. Honda civic/ integra Tyre R engine is running on high compression; somewhere 11:1, Mivec engine, 4age 20 valve and SR16VE also running on higher compression somewhere 11:1. BMW have a engine running at 12:1 compression!! those running on higher compression engine wont face the problem of piston crack if the cooling system is working properly and you dont over modify the engine.
as conclusion, with stock engine it is safe to use iridium plug. high performance plug doesn't give u any much power improvement compare to stock cable. remember your stock cable cost u RM300-500!! not cheap ok!!
certain high performance cable will have inteference with your radio frequency so if u like to listen radio on your car please dont use cap ayam high performance cable. if you want greater sparks, buy iridium plug don't waste $$ buy the big big cable!
