You don't need to jack the car up to install it. All you need is 3M tape and it helps a lot if you can get that 3M tape adhesion promoter because it really makes the tape stick so much better. Oh yeah, make sure you use a wax remover before you put the tape on as well. It's easy enough to install it yourself, but if you can find a good body/customization shop, they probably have the packets of the adhesion promoter sitting around and it would take them all of 10 minutes to install the diffuser for you without making rookie errors. They shouldn't charge you very much at all. Some people don't use the good tape, adhesion promoter, or don't remove the wax and wonder why the tape doesn't work well.

I like the description in the link I provided:

Salesman Note: A question I often get asked is: "Do I really need 06396 Adhesion Promotor for the attachment tape to stick?". Answer: Yes and No. No, if you don't care if it falls off after a period of time. Yes, if you don't want to worry about the tape turning loose. The tape turning loose is not the real problem. It's the fact that you're taking a chance of loosing or destroying a high priced molding or emblem. Some moldings may cost as much as $200.00. Sometimes cutting costs up front isn't economical in the long run.
