These allow you to put seafoam or other intake cleaners in a direct injected MINI MUCH MUCH easier! No worries about sucking too much in or spilling it. Just fill up the canister with your favorite cleaner attach to the vacuum line and let it do it's work! Once you have used the supplied intake cleaner you can just as easily use Seafoam, BG, or any other liquid of your choosing. I have 2 available. These two are BRAND NEW in the box never been used. I also have a bottle of the Run-Rite Intake Cleaner to go along with it. In addition, I have the Run-Rite pedal depressor tool so you can do this by yourself without someone needing to keep the engine revved up. I have (2) Professional Run-Rite #9600 Intake Cleaning Servicing Canister tools. They are $100 each. If you buy both ($200) I'll give you the pedal depressor for free ($40 tool). NO SHOP AIR IS REQUIRED! These run off vacuum lines (PCV or Brake Booster vacuum line) to clean your entire intake, manifold, upper valves, etc. I am including with each one a bottle of Run-Rite #1003 Intake Cleaner. Once you have used it in the future you can use BG or Seafoam or any other liquid of your choosing. This is perfect for the DIY or mobile mechanic. Hard to come by these tools and brand new is even more difficult. You can spend $150 for Napa's version, but it doesn't have a canister and you are stuck using THEIR proprietary chemicals or reusing their plastic bottles. This one allows you to use any chemical you want with it's canister! This is the only way to get a complete clean in some Direct Injected engines (BMW and MINI Especially)!

(I will sell this for $30 by itself). Keeps from having to have an extra person there to keep the throttle up to 1800-2000 rpms while using the tool. The 9600 tool consists of: A black powder coat finished canister All fittings are made of solid brass and aluminum A brass control valve with Teflon seals A proprietary metered drip tube Vacuum gauge A unique vent tube that provides for atomization of the intake cleaner. This provides even distribution of the cleaner for a more thorough cleaning, in addition to adding a measure of safety to the process. The tool is extremely durable Service time = 20-25 minutes (for 12 oz. of cleaner)
