    The gold tape does work especially for my aluminum intake box. The accelerator does a good job sealing the fenderwell hole but an additional layer wouldn't hurt I imagine.

    I ended up cutting the intake box just enough to be able to fit the accelerator+clamp to get a nice tight seal. @pvn.beluga was able to get his installed without any cutting but that's gonna be a real tight fit. Not sure what @Tundra234 did to his. I'm sure he'll chime in :thumbsup:

    If you decide to cut the box, just make sure you don't cut too much off to not be able to slide the accelerator on.

    Ooof, I'm sure he can, we've been in constant contact lately with the tail lights. That said, I'd like to keep this truck a good, long while. If I go SC, I'll, uh... UH... Push it, a lot, and beat on it, a lot!

    @00h2itrYou’d want to install the accelerator onto the intake and then fold the accelerator into the fender well hole in order to not cut the box it self.

    Awesome, I may have read that a page or 2 back as well, and forgot as I was doom scrolling last night after hours. I'll give that a go. I don't mind cutting the accelerator at $20 for the part, but would rather not on the brand new intake if I can avoid it.

    I think you might be cutting both? Honestly, try to squeeze it in before you do any cutting.

    @pvn.beluga in this image, it looks like you didn't cut the intake, but only the accelerator, is that correct? And no hose clamp? Any feedback there?

    No, didn’t cut anything at all. Just push the accelerator all the way onto the intake hole.

    Can OTT compensate the N/A tune to account for the Stillen and a DD exhaust?? Thanks!

    Heard back about tuning. OTT states the intake doesn’t do anything and that you can’t outflow the factory box even on SC trucks. They said it skews the fueling actually. Exhaust they say is just for sound. Welp I’m already down the rabbit hole. At least it will sound awesome haha. Seems people on to forums feel differently. Still fun to tinker. I really don’t think the intake will make my truck worse.

    Literally got my truck OTT tuned today and the installer told me the same thing, the Stillen CAI was a waste of money, he said certain exhausts can add some HP/Torque though..

    I’ve seen Dyno videos ( from Stillen) proving 10-20HP & TQ gains though.
    https://stillen.com/products/2014-2020-toyota-tundra-trupower-by-stillen-cold-air-intake-dry-filter

    IMO having 2 intakes with one being up front, seems like it would allow more/cooler air than just one.. but I’m no Toyota engineer.

    Agreed. I feel like it can’t hurt. Will at least get better sound :thumbsup:

    I'm still happy with mine. Sucks I'm gonna have to remove it for smog here in California but it'll go right back in soon as I pass.

    So drove in my first rainstorm. Noticed a bit of water coming in the front tube into the box. Anyone else have this happen? Should I be concerned?

    I haven't driven mine through heavy downpour, we don't get much here. Is it just droplets of water that came through or do you have a pool of water on the bottom?

    No pool. A tiny bit in the front driver side corner. Looks like mostly water droplets coming in. Just went back to check it. Most of the drops dried up. All that was left was that corner. I can also see where some droplets splashed up onto the lid.

    Where did you get the dry filter for your Stillen? I'm leaning that way now PXL_20250711_204817123.jpg

    I also got mine from AFE. I actually had mine custom made by them. I gave them the inlet size, the length, and the max diameter that would fit. They made it to the exact dimensions I requested.

    Where did you get the red tube? I need to swap mine. I'm curious to see the difference between the oiled versus the dry filter. When I ordered mine, she recommended the oiled due to the humidity.
