Quieting the RAI (Snorkel) Sound

[dunder]

First, let me say the sound the snorkel makes is a blast. Second, my wife has the completely opposite opinion. She hates loud cars. Naturally, the snorkel on her side of the truck is too much for her. I figure I owe her one since I bought a new car and truck for myself this year. So I decided to see what can be done.

The first option has already been posted elsewhere. Just remove the rubber cap on the lower front of the air filter box. It should be the first pic below. The was some snorkel noise reduction, but not enough.

The second attempt was to disconnect the snorkel from the air box. The air filter box fits snugly, but it’s only pressed onto the snorkel inlet. To remove the snorkel inlet, there are two bolts to be removed, and then squeeze it and pull forward to remove. Maybe it’s a little quieter, but not much. It’s the second pic.

My third effort was to insert a shop sponge into the snorkel cavity. I still can hear snorkel sucking air during hard acceleration, but that’s about it. I think this is a good compromise for noise. BTW, the sponge did not get sucked out of the cavity. The sponge is pic three.

The fourth step was to cover the air box inlet near the snorkel. It’s not a perfect fit, but the rubber cap in step one fits well enough. At this point the snorkel is silent. See pic four.

Now the final step will be a test drive with my wife tomorrow to see if the sponge is enough or do I need to use the rubber cap.

The snorkel lives to fight another day. The misses said it’s quiet enough with the sponge.

Has anyone tried replacing the scoop at the top of the intake with a cyclone filter cap or something like that? I don’t have the snorkel on my Tacoma, but I was thinking of having one installed at some point down the line.
I wonder if that would make any difference with the sound.

I removed the rubber cap, then disconnected the snorkel inside the inner fender and then blocked the rest of the snorkel to the passenger side, this kept the air intake from the inside fender well and under the hood.

Option #5: tell her to get used to it.

that’s what I said. Sound deadening glass, windows stay up. Keep that new car smell as long as possible.

Yeah, that didn’t work. She was complaining with the window ls up.
