No real performance mods out there. Nothing gives our cars power... Not without tuning capabilities. Other than that, these mods are to sound good, not run fast.

Check out our vendor sections though, they have companies that tune your OEM ECU now for a bit of a power jump.

There's nothing ricketty-ricer about the intake plenum being replaced. There's tons of other cars out there who benefit greatly from replacing the plenum (Lexus vehicles are of course, an exception).

Also, upgrading the intake hoses to the F-Sport models give your 350's some nice V6 growls. There's a forum user on here that threw his OEM intake system out and put in the 4GS one in its place:

I, for one, definitely dont consider that "ricketty-ricer".

"There's tons of other cars out there "
thats what I'm talking about,"other cars",not the gs350
I have seen both delivery types tested and tested some work,some are just crap.
some people say that the air coming needs to flow freely,others say turbulence help mix the air/fuel mixture
maybe it works better on turbos,who knows
i'd recommend doing some research and concluding for yourself which is best
that's what this is all about
