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.
my car sounds aggressive with this exhaust n i felt the acceleration is smoother n more power when the vtec kicks

I would have rated these a 5 if it were not for the fact that they needed some additional sealant around the lens. Luckily I had some left over rubber sealant lying around - I'd read about and experienced this before with my other aftermarket lights. Overall I am very satisfied with the product and the customer service. I was notified of a short backorder (about a week) shortly after placing my order, which happens from time to time. Wes kept me updated and called me as soon as the item left. Great guys to deal with!
