Jon143 posted a topic in Lexus IS 250 / IS Turbo / IS300 / IS350 / F Sport ClubI have had my IS250 F Sport for a year now and and I am considering a few upgrades. My priorities are intake and exhaust. I am looking at the Lexus cold air intake and the exhaust as well. Is it worth going with Lexus or should I look at other sources? What about the shocks? I was looking into the Bilstein shocks offered by Lexus. Thanks for your comments in advance.
