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, Volvo S40 vehicle manufacturers equip cars with intakes that bring air inside to the Volvo S40 engine directly. Volvo S40 Air intakes are designed to provide the least inhibited route possible for the air to reach from outside the Volvo S40 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 Volvo S40 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. Volvo S40 Cold air has more oxygen, for instance, so Volvo S40 cold air intakes have become popular Volvo S40 intake upgrades. Other upgrade types focus more on greater Volvo S40 air intake capacity period, but either way, you’ll end up with a better performing engine using an upgraded Volvo S40 air intake system in your car.

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!
Great product great price
I have the full H&R set up on my car and I love the quality of the parts. I have sold my Eibach springs to get the H&R coilover and I know my decision is right! Thanks Ilovebodykits
