Is this the right bulb for our IS? Thanks

 

yeah it's the right size for our car but it wouldn't improve your light output. Why not just spend some money and buy a real HID kit from XD. You can get the xtreme kit for let then 300 shipped. Remember, you bought your car for 35k+, it deserves better.

 

that's true. But i'm thinking of getting tanabe exhaust first. Gotta save $$ for the exhaust

 

if you go to your local lighting shop, it would probably be cheaper than 300 installed.
