Not worth it unless you have an N/A beast or FI engine. They look pretty though.

N/A=naturally aspirated
FI=forced induction

pretty much unless you have a motor that requires alot more fuel its worth less

and no you can't really see it when its installed.

not worth it in my opinion.

Unless you've done some other stuff, bigger injectors aren't gonna help either.

Same displacement, same cams, same pistons, same same same...
If you inject more fuel, all that happens is you run rich & that doesn't help anything.

^^^ then the ECU trim cuts down the duty cycle time and you are left with the same power, burning dirtier and less efficient.

I will be doubling my engine's output, but the stock fuel rail is fine for my application.
