Like many here, one of the first mods we did to the new hottie after delivery was to remove the intake sound tube.
And again, like many, I chose the kit offered by Cool Tech. After receiving the kit in the mail, and upon inspection, I was a tad disappointed in the cheesy rubber cap/clamp combo. I thought I could do better.
For the last 12 years I have overseen all machining operations for our company. We are an OEM manufacturer of machine tools for the printing, packaging, and converting industries. Since 1991 I have held my Journeyman Machinist's card. I have access to all the latest in CNC machine tools and with an open lathe, and a detailed drawing in hand, I came up with this cap to replace the Cool Tech cap/clamp assembly.
This cap is CNC machined from solid 6061-T6 aluminum and features a hand brushed finish. Due to variances in the injection molding process of the Boss intake tube assembly, the caps are machined .010-.012 smaller than the OEM diameter of the sound tube protrusion lip. These caps are designed to have an extremely tight fit over this protrusion. A press fit to be exact. With this tight fit there is no need for clamps or set screws. However, due to variances, each tube may be .002-.005 different in size than the next, hence the reason this cap is machined the .010-.012 smaller. With that said, custom fitting may be needed to achieve the desired fit. Custom fitting can be achieved by lightly sanding the sound tube protrusion lip. This cap is designed to be fitted by hand with no tools required. Just a super strong wrist and hand to insure a tight, press fit.
I have posted a photo here in the How To forum under Sound Tube Delete. There seems to be many interested in purchasing this cap. I have made additional caps and can now offer them here for sale to BMO members. Each cap comes complete with detailed install instructions. I know, pretty easy, but I want all to be aware how easy it is to sand the sound tube protrusion to small making a sloppy fit. This is not what is wanted. Again, cap is meant to fit extremely tight. Many will not need to sand the lip at all. I also include a piece of 120 grit paper if indeed sanding is needed. For those that track there Boss regularly, I also recommend installing cap with a good coat of a reputable epoxy glue found a most hardware stores. Once cap is installed, it should not be removed, nor should it be able to be removed. This sound tube protrusion boss appears to be sonic welded to the intake tube, and breakage may occur if cap is removed.
If you are interested in purchasing this cap, price is $23.00 and this includes shipping via USPS to your address of choice.
Interested parties may contact me via email at [email protected] for payment instructions. I prefer Pay-Pal. I will respond to all emails, and once payment is received, I will ship cap out the very next day.
Thank you to all for the interest.
