Louis, please don't think as it was an attack of sorts as that is not how it was meant. Just thinking out loud. I agree for recreational type of use the knock offs are great. Just thinking that .4 is .4 in terms of go power. High 8's would be great, but low that .4 would put you into mid-low 8's, which for a "mild mannered" pump gas turbo car is even just a bit more impressive....
