Racing Beat Oil Cooler Stainless Steel Braided Hose Set..

Just was wanted to know if anyone was running these lines at all on the RX-8
i've read some information on about it that it replaces the 8 lines that we do have to only 3. this set is offerd thru them for $449.00. to me that expensive for the lines when i found a place here that can do 6 line for $75 using the same ealrs hoses and such. But my main question is how more efficent would it make the oil system by reducing the lines down to only 3.

 

Link to the 6 line for $75?

 

Dunno bout efficiency (beyond the fact that 3 lines have less points to leak than the stock 8), but the stock system is usually quoted at >$1,200 bucks from the dealer.
