I detailed my buddies IS350 yesterday and damn what a difference from my IS250AWD! so i am looking for little upgrades to help performance wise. I was looking at the JoeZ's intake pipe is it worth it???? do you feel nething? hows the gas mileage? this is for IS250 owners. Is350 owners ur luckier than u know, i feel torcherd after whipping the Is350. Really its nite and day!
