Cold Air Intake And Sport Exhaust On Is 250?

[angelokings]

Has anyone added the new ISF accessories like the cold air intake and sport exhaust to their IS250? If so, how is the acceleration now? Is it worth it?

The IS-F uses a complete different engine, none of its parts will work on an IS250.

If you mean the F _sport_ products, which have nothing whatsoever to do with the IS-F, you would be looking at somewhere in the 3-5 hp range for the intake and 5-7 hp for the exhaust. If that's worth somewhere around $2000 installed is up to you. But for not a whole lot more than that you could've picked up over 100 hp getting a 350 instead.

I'm sure it'll make your car SOUND faster. Most CAI and exhaust combos will add aroun 10 hp, that's only about 5% increase for the IS 250 and will probably cost around $1k-$2K installed so not really worth it IMO.

ISF accessories will not work. However LEXUS has a line of F SPort Accesories for the is250 and is350.
