Cold Air Intake

Trailboss75 · January 28, 2019

Does anyone know if this would fit a 2019 Silverado Trail Boss 5.3L V8?

I sent an email but have not heard back, also tried on line chat, but she couldnt help as well.

Has anyone installed a cold air intake on their 2019 Silverado yet? which one did you get and are you happy with it?

The answer is No.

2019 T1 Gm trucks have a completely new air intake setup that comes thru the top of the grille and to the drivers side for intake.

The intake picture you posted is for the previous gen K2.

To the OP, unless you live in central America, there is plenty of cold air to go around right now, I belong to other forums and the most popular topic is where is my block heater plug, lol. With a new p/u with a new intake system, I would bide my time, let someone else be the guinea pig to see if a CAI is worth it on this new generation.

Yeah, I found that one, but with only 13% more airflow, its not worth the cost, considering the K&N for previous year is only $280. I will wait for K&N or AFE to produce something. At least I hope they will!

ANYTHING with a GM label on it automatically fetches about 50% more.... LOL

K&n has their 2019 Silverado intake up for pre order on their site. A rep told me they should ship out soon since production has started.

That’s great news, good find! Now I’m curious if we have to tune the engine after installation? I know some others said that might be necessary.. but i didn’t see that in the instructions.

I was one of those checking every other day on their site to see when it would be available lol and that I know of you don’t have to tune it the computer will eventually adapt to the extra airflow and change what needs to be changed. The GM intake comes with the “tune” so the computer won’t have to do it itself. (Don’t quote me on this information it’s just something I got told)

On the 6.2 per the webpage above, it says it increases 17% airflow, I wouldn't imagine that there is that much adjustability in the ECU perimeters for that difference. Which is why they have a calibration for the intake.

It's a bit expensive for plastic and a rubber hose connected to the throttle body...

New Era Performance released theirs. Expensive at $400+, but 16hp/21tq on the 5.3 seems fairly good.

Im was gonna wait and see what else came out but the plan is to dyno before and after the intake for my 6.2

K&N saying theirs makes 15.7hp/32.5tq on the 6.2

I wonder what this fine print means:

“Horsepower gains based on similar vehicle dynamometer test. Results will vary.”

Those numbers seem pretty sensational and don’t really mesh when you consider the numbers gained from the AT4 off road performance package, which includes both the GM performance exhaust and the GM intake.

“Thanks to these additions, the AT4 Off-Road Package delivers 435 horsepower and 469 lb-ft of torque - increases of 15 horsepower and 9 lb-ft of torque over a Sierra equipped with a conventional 6.2L.”

The GM exhaust from that truck is listed in the accessories store as being good for +13hp and +8tq by itself. Simple math would then indicate that the GM intake is then only good for +2hp and +1tq. That would explain why GM doesn’t directly publish the gains from the intake apart from a % airflow increase...pretty sad.

So, either the GM CAI is terrible, the K&N is really great, or someone is lying???

Curious what everyone makes of this because I am definitely in the market. That said, I’m not in love with using a K&N oiled filter and destroying my MAF sensor...
