yeah that's not helpful...i tried that before posting and couldn't really find a solid answer hence the post. everywhere just says more power...and so does all those ebay chips and intake spacers and all the other bogus power parts. i was looking for actual information, but that's fine you don't have to help inform your customer base on the purpose of the product you're selling.
not to be capt obvious but my first search on google turned this up with the very first result.
"The BG Fuel Systems’ Heat Sink is a fuel coolerdesigned for use with flow-through-style fuel
pumps. It is a re-cirfculating bypass equipped
with a one-way check valve that is particularly
effective in cooling fuel and fuel pumps that
operate continuously. The fins of the cooler
dissipate heat from the fuel system, allowing the
pump to run cooler and prolonging its life."
and that's not mentioning the help of detonation and hp.
