An internal combustion engine uses oxygen just as fires require oxygen to keep aflame. There is no internal oxygen tank in a car for this purpose, as that wouldn’t be very efficient. Instead, Smart vehicle manufacturers equip cars with intakes that bring air inside to the Smart engine directly. Smart Air intakes are designed to provide the least inhibited route possible for the air to reach from outside the Smart car all the way to the engine, though stock versions aren’t always the most effective.
For that reason, many car owners turn to aftermarket Smart air intakes to increase the effectiveness and efficiency of their vehicles’ intake capacity. The greater the amount of oxygen supplied to the engine, the more power it can produce. Smart Cold air has more oxygen, for instance, so Smart cold air intakes have become popular Smart intake upgrades. Other upgrade types focus more on greater Smart air intake capacity period, but either way, you’ll end up with a better performing engine using an upgraded Smart air intake system in your car.

Was ify after reading some things in forums about this site. But it was a very good buying experience. tje exhaust sounds great and really simple to install other than the pressed bolts on the first flange. shipping took a week.
This is my second set of spring for my GTR. I used to ride with Eibach but the front height is higher than my rear. Swift spring rides perfect. The height is even so my car dont look like a drag race car anymore. lol Anyways. I love this purchase
Got the duraflex hood for my Corvette, I like it. Good seller
Nice product, only took me about 20 minutes to put it on my car.
