I dont know if you want to do that but that alot of work. You have to buy new harness with switches. 9005 is a high beam bulb and I think it is 85W but not so sure. 9005 bulb will not fit in the car's connector cuase it is for a 9006 bulb plus 9005 bulb draws more power so you will have to change the harness as well.
try the Sylvannia first and if you are still not satisfied let us know and I will explain the conversion process
