Well I was talking to my friend how has an IS300 and he was telling me he
put an IPR on his car. He says you attach it to your fuel line and intake
and it "suppose" to make your car run smoother and save you gas. Anyone
heard of this? And does it really do what my friend described? Thanks

FPR? Fuel pressure regulator kind of sounds like what you're describing, though I wouldn't use one in an attempt to save gas.

x2. Not sure what an "IPR" would be...

Inline pressure regulator?

From what I know, an inline pressure regulator simply makes sure you have constant fuel pressure. It's used in small engine applications frequently to ensure that, even though the fuel from the tank is erratic in pressure due to constant movement, the pressure going to the actual delivery system (carbs in most cases) is constant to keep RPMs stable and not have your ATV rip your arms out of your sockets.

I don't see how adding an IPR (if this is truly what he's referring to) would change anything seeing as it does the same function as our FPRs.
