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. 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.

 

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.

 

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.

 

During our development our team noticed that the factory

 

¾ and 1 ton trucks actually have scoops in their radiator shroud designs also which confirmed that the True Power by STILLEN cold air intake scoop for the Chevy Silverado was on the right track!

 

An additional benefit to this air intake is that it will work with any aftermarket air intake system that utilizes the factory air intake scoop.

Took more time to make holes bigger to fit push pins in than it worth
Mounting holes off not aligned for the money I don’t think it’s worth the price. Fit and finish could be so much better.

NIce bit holes off slightly

Overall, great product. 4 stars because mine didn't line up perfectly but nothing a little drilling the holes out larger didn't fix. Everything seem shifted on the outside holes (L or R ends). No matter which way I pushed over, one side or the other was a bit off. I tried working from the center out as well but both sides where off then. I settled on the drivers side being off and just drilled the holes out a bit. Owned the truck since new so no accidents either that would throw anything off. Who's to say it isn't Chevy given some of the other corners I've seen cut on these trucks. This is thicker than the factory scoop by quite a bit too so good on Stillen for making something better than OEM. The finish is nicer on these as well even though you will rarely see it I was impressed with that. My factory one seemed flimsy compared to this. I see no way to upload pictures, sorry. Overall I am happy with it and I think anyone else would be too. Took all of 20 minutes including drilling a couple holes out. Very easy install for 2020 Chevy Trail Boss 5.3
