Shane Smiley

2014 Chevrolet Silverado 1500

What made you choose this particular product?

5.3L/6.2L compatibility

Is this your first time buying from this brand? Did you consider other brands?

Yes, first time buyer. Had considered other brands like Volant, K&N, S&B, and others, but liked AFe for the 5.3L/6.2L compatibility I will need when switching to the ported LT1 throttle body.

Was it easy to install? Any installation tips that will help others?

I installed this myself, and it was honestly fairly easy. One thing to note is that there is a rubber post on the bottom of the intake box itself that slips into the tray where your OEM air box was. Feels kind of loose and sometimes feels weird because it doesn't have a full seal around the old air box opening in the fender unless you push it all the way against it. Other than that, it's honestly fine. Has a great sound and the truck is so much fun to drive with it.

Once you've had a chance to use the product, did it meet your expectations?

So far, so good. It always puts a smile on my face when I pop the hood and see it there.

Any additional comments?

If you are looking to make some additional power and you have a bit of a budget along with the possibility of doing the L86 (or LT1) intake manifold/LT1 throttle body conversion on your 5.3L, this a great intake to buy because it will already have the adapter you need for both the 5.3L and the 6.2L. Will make the throttle body/intake manifold change very easy.
