Wind splitters can offer you that edge you need to beat the competition, be it through faster lap times or simply by accruing more style points. If you have a rear wing for more rear downforce, it might be a good idea to look into a Audi S4 wind splitter to even things out up front, especially if you're planning on doing any serious racing. When ordering your Audi S4 wind splitter, be sure to also order some wind splitter support rods if they're not already included.

Wind splitters are different than canards in that they attach to the underside of your front bumper rather than on the sides. A new Audi S4 wind splitter can either be application-specific or universal, and is usually attached with bolts and support rods, which will help keep the wind splitter rigid and at a proper angle for maximum effective downforce over your Audi S4 front end. Wind splitters are usually made of either fiberglass or carbon fiber, although aluminum versions are also sometimes available depending on the manufacturer and application.

Q: How do you install a wind splitter?
A: They are normally adhered to your factory front bumper using rods, which are normally sold separately on our site.

Q: What is a wind splitter? Why buy one?
A: According to APR Performance, "A Wind Splitter is a product you add to the bottom of your front bumper that is designed to decrease front end lift and exert downforce. By creating a high pressure area on top of the wind splitter, high pressure air flow is restricted to flow underneath a car. With low pressure below the car, the effect of lift is reduced and a driver can gain from the extra traction and control. These days, there are some really great-looking splitters available. Some are made of carbon, some are made to be painted to match your vehicle color. So these days you get your downforce in style!

Q: Are wind splitters made specifically to fit my car?
A: Not all of them. Many we sell are universal, and some are car specific. Check the 'fits on' listing right next to the product as shown on our website to see if it is universal or car specific. Either way, it can still have the same impact.

Q: Do splitters include the bumper?
A: No, products listed as splitters do not include the bumper, although some of the bumpers we offer do have splitters built into them.
