When breathing you fill your lungs with air, delivering oxygen-rich blood to all parts of your body. It is believed that yawning is the need for air. Next time when on the important meeting you feel like yawning, take a deep breath and avoid needless attention from your boss. Unlike your lungs, your engine is not able to breath deeply, especially if it has a stock air intake system. Stock air intake systems are designed to eliminate the noise of the engine, making its humming as quiet as possible. The piping of the stock intake systems comes very twisted unlike the custom systems which have piping of a larger diameter with the less amount of twists and turns. The twists of a stock intake system make them highly-restrictive in regard to overall performance of the vehicle.
Custom air intake system replace those under-performing factory installed intakes. Custom intakes provide better air flow to the engine improving overall performance including: power, torque and gas mileage. In comparison with the factory air intake systems custom ones give approximately 5-16 hp increase on normally aspirated vehicles, and 15-30 hp on the turbo and supercharged ones.
K&apm;N and Volant are known to be the leaders among the aftermarket brands. They became really popular producing high-quality aftermarket air intake systems and air filters. All these systems are designed and tuned to fit exact vehicles. K&N intakes and filters are produced from highly durable materials that stand far beyond the stock systems. Though there is a question, if these systems can be compared. The difference in these systems is the combination of intake pipe with a heat shield, which prevents heating of the air float. The system can be easily disassembled for cleaning and maintenance.
Volant products are produced using patented technologies that provide constant air flow to the engine. These products also feature an enclosed air box that improves performance, gives power boost and improved gas mileage by 1 to 2 mpg. Cold air intakes like Volant Ram Air Scoop for the Chevy give fresh air flow at high RPMs, when it is needed most. Volant Ram air scoop is produced of polyethylene which is a heat shield itself. Volant produces air intakes specifically for most vehicle ensuring perfect fit. The range of products includes high-performance air filters that need to be cleaned once in 35,000 - 50,000 miles and a brand new product PowerCore air filter that requires cleaning once in 100,000, that is unbelievable.
Choosing among the available modifications of intake systems, you can pick the application that will not only give you a noticeable power boost, but will also reduce the necessities to visit the gas stations.
