what difference would there be in terms of these compaired to a genuine magneti marelli one such as this....

i kniow alot of people say only use the genuine items but are they so much better?

 

made in china for about 33p arnt they?

personally,i would not want to risk a 3k-10k engine to save £20.

 

yeah i will end up going marelli but just wandered what the actuall difference was if any, as oftern parts are all made by same supplier then badged so to speak.
