STILLEN is excited to announce the much anticipated launch of the 2019 and up Chevy Silverado Cold Air Intake Scoop

The factory air intake system on the Chevrolet Silverado 1500 is a very unique and creative design.  During testing our engineers placed multiple temperature probes throughout the engine bay and access panels of the Silverado engine bay in order to find the coldest possible air source.

Additionally, Chevy and GMC uses a latticework type of material over the top of the intake scoop design. This latticework material increases turbulence, and every time you work the air, you’re introducing heat into the system.

With that being said, we looked at the design and we saw areas of opportunity to improve the performance. Also to reduce the intake air temperature and increase the air volume.

Now the intake scoop has a simple flow through design. The air comes in through the grille and straight into the intake tract. In fact, the scoop actually isolates the radiator heat.

We are very proud of the STILLEN Intake Scoop for the GMC Sierra and we’re even more proud to say that this is manufactured here in house in Costa Mesa, California. Since 1986, STILLEN has been a leader in Urethane manufacturing and high performance automotive parts and accessories.

After many request, STILLEN is excited to announce the launch of the new Trupower by STILLEN Cold Air Intake Scoop for the 2019+ GMC Sierra 1500 TP403503.

During our testing of this scoop design on the Chevy Silverado, we saw significant reductions on the intake air temperature. Additionally, we saw that the vehicle was able to cool itself down much faster through the intake air temperature sensors. We were able to get these recordings through the factory OBD2 system.

This intake scoop system takes advantage of the factory intake design. Where they’ve incorporated a latticework type of material in this front panel. So, what happens is the air comes in through the grille, works its way up the face of the radiator. Then it goes through that latticework material and into the intake tract.

To make the most efficient and coolest air possible design, we’ve eliminated the first two steps. Now we just have a simple flow through design, where the air comes in through the grille and straight into the intake tract. No longer is it being heated by the radiator. In fact, the scoop actually isolates that radiator heat.

Additionally, that work, as it goes through the lattice, is applying additional heat and turbulence as it works its way into the intake track. With a STILLEN Intake Scoop, you don’t have that problem anymore. The STILLEN Intake Scoop fits all the different models of the GMC Sierra 1500. It also fits all the different engine sizes for that particular platform.

2019+ Chevrolet Silverado 1500 Trupower by STILLEN Cold Air Intake Scoop

To solve the two problems with this otherwise fantastic design the design team at STILLEN began by creating a proper scoop.  This scoop lowers the base of the radiator shroud to be in line with the top bar of the famous Chevrolet grille. This new design allows for the air to come directly into the intake system without being warmed by the radiator, or disrupted by the lattice type material in the radiator shroud.  This design eliminates the pre-heating and the turbulence caused by the factory system.


STILLEN is excited to announce the launch of the 2500/3500 Chevy Silverado and GMC Sierra TruPower by STILLEN Cold Air Intake Scoop TP403502. This product is something we’re very, very proud of.

When Chevy introduced their new Silverado 1500 intake design, they saw that they could bring air from the front of the vehicle. The air will go through the front grille, work its way up from the face of the radiator, go through a latticework type panel and then into the intake tract. 

It’s a very good design that brings the freshest possible air from the front of the vehicle. However, what we notice is that the air coming up the face of the radiator is also extracting heat from the radiator. Remember, your radiator is running around 200 degrees.

Additionally, Chevy and GMC use a latticework type of material over the top of the intake scoop design. This latticework material increases turbulence, and every time you work the air, you’re introducing heat into the system.

With that being said, we looked at the design, and we saw areas of opportunity to improve the performance, reduce the intake air temperature, and increase the air volume.

What we’ve done is we’ve taken that initial concept and we’ve simply opened up the intake a little bit further to allow direct air flow. We’ve removed that lattice work material so that air comes in through the front of the grille, into the front of the scoop, and straight into your engine.

On the Chevy Silverado 1500 and the GMC Sierra 1500, one of the things that we noted was that we could also lower the bottom of that scoop to get a larger volume of air coming in through the face of the vehicle. Unfortunately, on the 2500 and 3500, we’re not able to reduce that bottom surface because there is a transmission cooler that runs along that edge.

However, we noticed that on the 2500 and 3500, their only using about half of the opening of the air scoop. The other side of the panel is completely blocked off to airflow and thus increases the restriction. What we’ve done is we’ve eliminated that restriction. We’ve completely opened up that area.

So now you have 100% airflow going into your intake scoop.

Turns out, Chevrolet engineers did a pretty good job of finding a great source of fresh air. Knowing that repositioning the air intake would not be beneficial our team of designers began looking at ways to improve the airflow and find additional benefits.

2019-2020 Chevy Silverado 1500 TruPower by STILLEN Cold Air Intake Scoop - TP403501

Pretty quickly our team noticed that the path of the airflow was good, but quite disruptive.  The air had to travel through the grille, up the radiator, through the lattice work of the shroud then around the radiator shroud and finally into the intake scoop.

This presented two problems.

1) There is no natural path for the air to flow through.

Every one of these turbulent areas, every interference causes restriction and/or causes work for the air.  The goal is to get the air into and through the air intake system as cleanly and efficiently as possible.

2) The air is susceptible to being heated by the radiator.

The air must travel up the face of the radiator in order to make its way into the air intake opening.  Keep in mind, the radiators operational temperature is 180-220 degrees….Significantly higher than ambient.
