    After searching and reviewing many options to delete the sound tube from my Boss, I finally settled on what I felt was the, must functional, factory looking, reversible and cost effective solution.

    First was the firewall plug. I wanted a factory Ford grommet so I found this one. Many have seen it online and it works perfect. Pack of 4: $2.97+/- tax.

    Second was to find a solution for the now huge hole in the air intake tube. All the other options I had seen or found either looked cheap, out of place or just too expensive. So after much testing and researching I found this solution.

    1" Copper Pipe Cap
    Cost: $3.24+/-, from Lowe's. I'm sure I could of found this cheaper somewhere else, but I was tired of looking....lol.

    The copper plug is a press fit and as the inside of the sound tube port is tapered, it pressed in and sealed perfectly and will not pull through. Just for extra insurance, I did smear a very light coat of RTV around the copper plug prior to installation.

    So for basically $4.00 and 5 minutes of work, I think I found the best solution for deleting the sound tube. I may eventually paint the inside of the copper plug, and or I found some heat shrink caps that I may install over the fitting just cause...lol. I have put several miles on it since installation. I have had zero issues with the install and am very pleased. If anyone has any questions, please feel free to ask.

    Looks cool, too :)

    My assumption is that the CTE of Copper is going to be MUCH higher than that of the plastic, so it will expand faster with heat and you won't have to worry about it becoming loose or un-seated during use.

    That was my thought as well. Trust me, once I installed the cap, it's not going anywhere. :)

    I use that same Ford grommet. That is the same one that comes with the Cobra Jet cold air kit now. I use the same rubber cap that was used on the Boss 302S that Watson used during the build....

    Yes,
    that's the exact one.

    Watson had given me a spare and also provided me with the part number (6448K39). They also provided me a piece of stick on insulation that was also used in the build. It's the silver looking square you see in the picture you attached. I used the Ford Grommet because it looks neater and is "reversible".

    Awesome. Thanks for the part number. I'm sure that will help out others as well!

    No problem. I love finding out all the small details that went into all the Boss road and race cars. It's my nerdy hobby. Glad I could help....
