Sound Tube Delete Grommet Size

[mrbydangel]

Anyone happen to know what size the hole in the firewall is so I can get the right size grommet? Tried searching, but I can't find anything that gives an actual size.

If nobody else chimes in here, I can measure my spare one for you later tonight.

Btw, the hole for the grommet is in a hard to reach place from the engine bay side but very easy from the interior side.. 3 nuts to remove the gas pedal and the hole is just behind it

Grommet size:

Sheet metal thickness is .125" max.
The part# calls up a Ford Body Plug but searches only come up for a 21mm and this one is for a 31mm hole.

You're a lifesaver, thank you!

I've found elsewhere online the hole in the firewall is 1 3/16" which comes out to 1.18". So that is close enough to the measurement above to be the same. Do you just pop it into the hole dry or do they suggest a sealer of some type?

Steeda, and others, actually make a kit for this. https://www.steeda.com/steeda-sound-delete-kit-2015-2017.html
