If you use your vehicle to tow a boat or trailer, the increased airflow that provides a horsepower boost will make acceleration smoother and provide better power to tackle those uphill treks.

The boost in horsepower is accompanied by a satisfying rumble at higher RPMs. Add to that the fact that the GT 54-74104 is CARB certified and is legal in California and all other states.

The Volant intake meets or exceeds the Original Equipment Manufacturer (OEM) filter standard. >>> Check current price on Amazon

Consumers that have owned both a Volant cold air intake system and a different manufacturer’s system claim that the Volant is constructed of higher quality materials. The intake’s design and black color makes it appear more “stock” under the hood.

Volant air intakes are warranted for 1 year for material defects and 4 years or 100,000 miles for the filters. It is unknown at this time if the Volant intake has California CARB approval. Contact the manufacturer for more information regarding an exemption sticker.

Pros

  • Maintenance free filter, never needs cleaning
  • Improves engine efficiency
  • Filter is unaffected by moisture

Cons

  • Requires some disassembly for servicing the filter
  • More difficult to install

Why Install a Cold Air Intake on Your Silverado?

Cold air intakes are a fairly inexpensive addition when compared to other engine modifications and installation of these systems is usually able to be accomplished even by owners that have limited mechanical skills.

The goal of any cold air intake system is to not only provide cooler air to the engine’s combustion chamber but to provide a larger quantity of that cooler air. Straighter tubes and a larger filter will aid in that delivery. It is a proven scientific fact that cooler temperature air contains more oxygen, and oxygen is the critical ingredient that will allow your Silverado to give you more power when you punch down on the accelerator.

A more satisfying engine roar and increased performance makes a cold air intake worth the money, time, and energy you will spend on installing the system.

There is something to watch out for if you upgrade your intake system. If the system you choose has an exposed filter (one that is not contained in a sealed box), it may be susceptible to water intake on rainy days or with you drive through deep puddles of water. Sucking water into your engine is not a good idea, so be aware.

Except for that, enjoy the added horsepower and the awesome sound that comes with a cold air intake system. And also be sure to watch heads turn as you jump on the gas when the light turns green.
