If you have ever taken your car on a long road trip, you have probably noticed the incredible amount of insects that wind up smashed on your windshield.

One way to avoid these expensive damages and keep your car looking nice and shiny is to add an aftermarket GMC S15 hood deflector. Simple in design but extremely effective, GMC S15 hood deflectors mount to the front of the vehicle and redirect the flow of air up and over your ride to keep your hood and windshield out of the air stream. This adds tremendous protection to the front of your vehicle.

Air flow design is a complicated science, but you don't have to be a genius to understand that the reason your rear window gets so dirty has a lot to do with aerodynamics. If you thoroughly clean your rear window, then go for an hour long drive, you will undoubtedly be surprised at the amount of crud and grime that gets deposited on the glass in such a short amount of time. This is primarily due to air flow. Aftermarket GMC S15 rear window deflectors subtly alter the flow characteristics of air coming over your vehicle so that it keeps the dust and debris from settling on your back window. Here at Andy's we have a great selection of GMC S15 rear window deflectors in a wide range of styles and prices to ensure that you get the right product to fit your needs.

If your vehicle is equipped with a sunroof you have no-doubt suffered from the effects of wind buffeting and the excessive buildup of dirt. Wind buffeting is that annoying noise you hear when you open your sunroof at speed. It is caused by airflow and pressure differences which create a loud pulsing noise. The simple addition of an aftermarket GMC S15 sun roof deflector will make this noise vanish and allow you to enjoy warm weather driving once again. These GMC S15 Sun roof deflectors also shield your sunroof from dirt and grime, keeping it clean so that you can enjoy the sun or stars without looking through a haze of debris. Here at Andy's we have a broad selection of GMC S15 sun roof deflectors for you to choose from. With all of the top name brands available, you are sure to find the perfect deflector for your needs.

GMC S15 Convertible wind deflectors are a must-have for anybody who enjoys driving with the top down. Due to the way most cabins are designed, turbulent air gets caught inside the cabin, causing unpleasant buffeting and noise. With a proper convertible wind deflector, 75% of the annoying wind passing through is diverted over the cabin, allowing for a calm, relaxing drive where you can hear the radio clearly, chat with a friend, or just enjoy the fresh air.

In addition to keeping the glass clean by avoiding rain and dirt, GMC S15 deflectors also greatly reduce wind noise and buffeting when driving with the windows down or the sun roof open. By rechanneling the air deflectors allow you to listen to your music and hold normal conversations even with open windows. In addition to their functionality, GMC S15 deflectors also add a great aggressive look to your vehicle. Whether you choose a body color finish or a dark tinted look, the smooth contoured lines of deflectors are a great way to accentuate the shape of your ride.

Aside from bug and rock protection, hood deflectors are incredibly effective in wet conditions. Normally water is kicked up off the road into the air, and covers your windshield more than the rain that is falling from the sky. With a hood deflector the water is redirected over the car so you won't have to use your windshield wipers nearly as much. GMC S15 hood deflectors also provide a nice custom touch to distinguish your ride from the rest of the crowd. There is a reason that big rig truck drivers have been using hood deflectors for decades; they really work! Many of us hear at Andy's run these on our own vehicles with great results. They are an inexpensive way to keep your car clean.

In addition to keeping your ride free from dirt and debris, GMC S15 side window deflectors also prevent wind buffeting. This means you can drive with the windows down and not get that annoying pulsating noise that always drives you crazy. By keeping the wind outside, the cabin suddenly becomes a pleasant place to be regardless of whether the windows are up or down. They even help keep the rain out when the windows are cracked. We also like the subtle styling of side window deflectors, and think they give vehicles the perfect aggressive touch.

The rear of the car is a natural low pressure zone. So as air travels over the roof, the low pressure creates turbulence and actually sucks air back ward in a swirling pattern. When combined with the dirty exhaust that is exiting the rear of your vehicle this creates a cloud of grime that settles on the back of your ride. A rear window deflector works by forcing the air down over the back of your car. This prevents the low pressure zone and keeps the air velocity high so that dust and grime can't settle as easily. This basic design is extremely effective, especially in wet weather. If you are tired of cleaning your rear glass then you really need an aftermarket GMC S15 rear window deflector.

Many vehicles are equipped with sun roof deflectors straight from the factory. The main reason these deflectors are used is to reduce interior noise when the sunroof is open. If you have ever cracked your sunroof while driving on the freeway, you may have noticed that it is impossible to hold a conversation or hear your music. With the addition of GMC S15 sunroof deflectors, wind noise is dramatically reduced and it becomes pleasant to drive with some fresh air coming in. Sun roof deflectors also look great, adding a slight custom touch to any vehicle. If you own a sun roof equipped ride, this is one modification you should not do without.
