It is not like U think it is !! iT doesnt even reduce da cars life by 1 minute!!! And it is better for ur engine because ur plugs usually react with carbon and other stuff in da engine!
But Platinum does not react with anythin and is inert so even if u take it out after a year, it wont all be rusty like others and would be clean!! This is Y it is good!!
Plus it provides better combustion!! Cheerz!
I'd say get em and you'll never regret it!
