The ARM B58 Charge Pipe increases the diameter over the OEM charge pipe, resulting in increased airflow from the turbo to the engine, and improved throttle response. Upgrading the charge pipe on your B58 is one of the basic steps in ensuring your B58 is protected against a charge pipe failure. In addition to making sure you have a reliable means of transporting the charge air from the turbo to the throttle body, the ARM B58 Charge Pipe comes with Tri-Port capability giving you 3 options for tapping into the charge pipe for meth, boost, or nitrous.
CONSTRUCTION
The ARM B58 Charge Pipe starts at the turbo with a CNC machined fitting which seals tightly at the turbocharger outlet port. It then transitions to the mandrel bent 2.5" piping for smooth transitions and to match the turbo outlet.
The 6 layer reinforced silicone coupler connects the 2.5" piping to the larger 3" upper charge pipe section. This runs all the way to the CNC 3-bolt throttle body flange. The silicone coupler is secured using our constant tension T-bolt clamps to ensure that the connection doesn't loosen over time. The upper charge pipe incorporates machined connections for the temperature and MAP sensors to ensure a precise fit.
The ARM B58 Charge Pipe incorporates Tri-Port 1/8" NPT bungs. These 3 bungs are useful for running a heavy dose of methanol injection, tapping in for secondary boost gauge, nitrous injection, or anything else your heart desires! More ports means more options, and with the ARM charge pipe you have 3.

No Rust, No Fuss, A simple but great Sink Item
Color: Black - 9.25″
For years I just had my sponges just laying on or around the sink but this year I decided I needed something to hold the soups and cleaning detergent. Along with not being too pricy and that is how I stumbled upon this sink caddy it has worked amazingly. It holds the detergent, sponge, and tube brushes with no problem and any water is drained out from the little spout underneath it.
You can adjust the dividers so you can have how you want things separeted from each other and with the bottom being plastic you don't have to worry about getting any rust there. If you need something to make more space around your sink this item will help you.

Functional neat and worth it!
Color: Navy Blue - 9.25″
This caddy has been even more useful than I expected. It instantly made my kitchen look cleaner and more organized compared to having wet sponges sitting on the sink. My counters look much tidier now, and the sponges dry out much better. It may seem like a small addition, but it really makes a big difference.

Makes the Sink Area All the More Organized
Color: Silver With Towel Rack - 9.25″, Color: Silver With Towel Rack - 9.25″
At first glance I'm sure most people might think this kitchen accessory is kind of silly; a caddy for your sponge and dish soap? But honestly, it makes the kitchen area look at the more organized and keeps things in place. I sprung for the model with the towel holder because I always feel weird about bacteria sitting in the wet microfiber cloth that I use for cleaning the kitchen countertop and my dining table. The little dowel allows it to dry very quickly.
The holder can be configured in a few different ways to accommodate your cleaning items. I like that it's wide enough to comfortably hold the large bottle of dishwashing soap I buy and it's the perfect width for Sponge Mommy/Daddy sponges.
I've had it less than a week and haven't had to wash it yet, but it seems like it will hold up well in the dishwasher and won't rust. Since I don't have any sponges on a handle, I may use the removable compartment for those (that you can see on the left in my photo) for other kitchen tools.

Un mess your kitchen sink mess
Color: Black - 9.25″
Just the exact right thing to gather all the sink doodads into one place. There is a little divider that is movable so you can adjust the sponge holder to your brand of sponge. AND it has a drain spout for the water run off. Very sturdy and handy sink catch all.
