Dash rattle after S&B Intake Install

I installed the S&B Cold Air Intake in my 2015 5.7 Tundra a few months ago. Sounds amazing (better than my TRD exhaust), but I now have a rattle in my dash. I removed my aftermarket stereo and felt around inside the dash while having wifey drive and I cannot put my hand on anything rattling. Any ideas?

 

Check the cabin air filter for something stuck in there?

 

I did that and no luck.

The sound is just to the right of the center of the dash (maybe a few inches to the right of the stereo and up to the mountains ddle of the top of the dash (at least that is where it sounds from the driver seat)

 

Can you hear it in the engine bay?

 

I have same CAI, no rattle here

 

Hard to say. It only happens on acceleration (not reving in park).

 

Did you put in the rubber side gasket and clear cover on it?

 

Maybe check your center speaker?..

 

I do not have a center speaker. I have felt around the space for the speaker with no luck. Sounds farther down inside the dash.

 

No on side, yes clear

 

Did you collect all your tools after install?..screwdriver may be fell between box?..and rattling against something?.

 

Good idea, though I did not use any tools inside the dash.

 

Is it possible the tabs on the engine cover aren't seated correctly? The ones that hook in closest to the firewall.
