- Boost Motivation: The performance cold air intake kit design aims to increase 8-12% horsepower and 6-12% torque, and the power that bursts out in an instant is relatively improved. A larger air intake means that the engine inhales more oxygen in the air at the same time, so that the engine can burn more fully. These design can help your engine to draw in more cold air resulting in better throttle response and higher explosive horsepower output,and creating an attractive intake noise
- Stable Performance And Easy Installation: The intake pipe is made of aluminum alloy, which is more resistant to high temperature, corrosion and heat dissipation than the original rubber pipe, effectively reduces the air intake resistance, and makes the engine burn more fully. Marsflex cold air intake kit is designed according to the location and shape of the original air intake kit, so it is very convenient to install and the service life is up to 200,000 kilometers
- Washable And Reusable: Every 5,000 kilometers, it is recommended to remove the inner filter element. You can wash and dry it with water mixed with detergent, or blow off the dust attached to the filter element from the inside of the filter element with an air gun
- Multi-layer Fiber Filter And Heat Shield: The kit includes a steel heat shield that features a durable carbon-black powder coating for long lasting good looks.The filter medium adopts high-density multi-layer fiber with excellent dust accumulation effect, and the filter screen is made of alloy metal, which is not easy to be oxidized, which greatly prolongs the service life of the product
- Warranty: 1-year warranty. Marsflex is always on your side, any problem you meet, emall me at once, and we will reply and solve your question as soon as possible

Definitely not the nicest piece but for the price it gives absolutely nothing to complain about, definitely adds some throttle response and is a super easy install on my 05 Silverado 1500!

Does the job
This kit fits well on my 2004 GMC Sierra. The finished product looks good and functions well. The kit arrives in a plain brown box and included no instructions. If you are mechanically inclined and understand how these kits work it should be an easy install. If you are a first timer and not super mechanical then this may not be a good kit for you. The increase in sound is noticeable under acceleration. Power increase and MPG are negligible unless you are installing other mods at the same time.
