you can trim your factory header panel to make it fit... i remember someone made a thread about that.... you will also need some sort of harness to make the bulbs work.. a 9007 to H13 harness... at this point it would prob just be easier to switch them over to HID's and get a 9007 Relay for them to make them work...
Just be aware:
The H13 is quite possibly the stupidest design for a bulb ever foisted on the public. The terminals are so small that they overheat, even at stock wattages, and melt the plastic housing of the connectors. Higher than stock wattage bulbs are offered, but not recommended. There are Chinese connectors that are being used to make these kits and no harness will fix the problem of to small of terminals. As of now no USA made plugs are made that I have seen and wouldn't solve the problem anyway.
You have the best headlight housings made now and the addition of Hellas harness and a set of their 80/100w 4k kelvin bulbs will give you fantastic lighting.
You can also do a fog bulb upgrade..75% as bright as Hids and mod the switch to use them with your high beams.
