  • 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
  • High Flow Intake Air: Marsflex cold air intake systems provide a less restrictive path for airflow, increasing the volume of air .Cold air intakes are designed to flow more efficiently than your car's from-the-factory. The shape of the filter is a cone, and the shell is made of high-strength aluminum alloy designed into a funnel shape. After testing, this structure can maximize the air intake and form a perfect ratio with the filterability of the product
  • 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

I love it. It didn't come with instructions but it is still very easy to install. I just watched a couple of YouTube videos and I installed it in about 15 minutes. Fit perfectly. Looks great.Amazing performance. Great craftsmanship. Great product at a great price. Highly recommend.

This intake kit is an exceptional upgrade for Chevy and GMC vehicles from 1999 to 2006. It boosts engine performance by improving airflow, resulting in increased horsepower and torque.The 4" intake and filter are made from durable materials designed to withstand high temperatures and harsh conditions. The included heat shield ensures that the intake air remains cool, further enhancing engine performance.Some users might notice a slight increase in engine noise, which is typical with performance air intake systems. However, this is often seen as a positive by enthusiasts who enjoy the sound of a powerful engine.Overall, this kit is a fantastic investment for those looking to enhance their vehicle's performance and add a touch of style.

Filter will not stay secured to tube due to the adapter being wrong size. Contacted seller and have gone back and forth with them for 2 weeks and they still haven't made right. Ended up buying another filter that connected directly to tube. So now I have more in it than a name bland kit.

I have never installed a cold air intake before so this is a first for me. So far it seems to be decent, no check engine lights have lit up or anything. It all seems to be made well, the welds are good.I was pretty annoyed that mine didn't come with instructions, so youtube to the rescue. After that it was easy to remove the original parts and install this set up. The only issue I had was trying to get some of it to line up properly, mainly the support attaching to the air box. The rest of it was pretty simple.I don't know if it will increase mileage or anything, but it does seem to have a little more power at least on the get go. For being a first timer to this, it went pretty smooth with the video I found. Not so sure about the filter, but I'll see if a KN filter will fit in the future.

Overall, this is a nice kit that is easier on the wallet than the more popular name brands. As other reviews have mentioned, NO instructions are included, but it wasn't too difficult to figure out how to assemble the pieces and replace the factory filter box along with the intake tube in my 2003 Tahoe.The filter itself is large and is a tight fit. The small rubber boot is a little loose on the MAF sensor before tightening the hose clamp. Upon opening the box, the stainless intake tube was a little scuffed, but could easily be cleaned and polished if you like shiny objects under your hood.I took my time and wasn’t in a rush, installation took maybe an hour to an hour and a half. While driving, the sound in the cabin is definitely noticeable under load, but was close to stock during normal cruising. I assume most people who get this will already have a louder exhaust and will be accustomed to increased engine noise.This is a worthy kit if you are considering a generic intake kit for your ‘99-06 GM truck or SUV. I consider this a quality kit in the under $70 range.Note: I had the opportunity to compare both Marsflex kits:APEN23001-M1APEN23001-M2During a side-by-side comparison, I found no differences between the two kits. Both included the same parts.

my only fault with these was that there was no instructions so i had to go off the pictures on the listing. Was not too hard without the instructions took maybe 30 minutes. things that would be helpfull to know when installing is to make sure you use the mass airflow sensor in between the filter and the pipe that were on your original air intake. also to install the metal box you will need to remove the metal plate that your air box attaches too, put down the metal sidwalls then re attach that metal bottom plate. if you dont you will be kicking water and dirt up at the cone filter. all in all seems to be a good kit drives just fine after install no codes or anything.
