I just bought a Grey Mica 07 IS 250 AWD. It is a great car but I need some more power.

I bought a LMS intake but what would you reccomend for decent gains. I am looking for bolt on only. Not sure what exhaust provides additional ponies. I don't want to sound like a blown civic.

Any help would be appreciated.

Thanks.

At this time, there isn't a lot of aftermarket stuff that add significant power to the 250. The LMS intake actually took about 1/2 hp off the stock system (but only with one car's dyno reading; more research is needed).

The only thing that would add more power on the IS250 is the IS350 engine...

Yup, you will actually lose power if you installed the LMS intake and gain a lot more noise. I installed and took mines off awhile back. But I heared their LMS full catback exhaust is pretty good if you don't mind it being not CARB approved. If not, look for Tanabe or Greddy axle-back exhaust for now.

I'm hoping the HKS or Greddy is working on a Turbo kit for the IS250.

I feel the same, even though I do not drive fast, the power is not there when you need it. Either to speed up on the freeway or what not. But the aftermarket parts are growing for the 2IS and that's a good sign.
