This kit comprises the following:

1). One quart-size highly durable glass jar.
2). Converted jar lid (made of durable white plastic) with electrodes, valves, wiring terminals, etc. This is a very unique design, with SPIRALED electrodes rather than flat ones. Due to the magnetic forces created by the spirals, this design produces MORE HHO - for LESS current drawn out of the car's battery. This is your Electrolyzer.
3). MAP Sensor Enhancer – a must have for great fuel economy.
4). Fuel Heater: pre-heats your gasoline for better gas economy, a great companion to your Hydrogen-On-Demand system.
5). PCV Enhancer: another companion to your Hydrogen-On-Demand system that improves the PCV function, protects your engine and saves gas.
6). Fuse holder (w/15 amp fuse) + installation wiring with ready-to-hook-terminals. Plus quick splice connectors for easy electrical installation. Plus flex protective tubing.
7). Vacuum line T-connector. Helps you hook up the Electrolyzer or Vaporizer to the Intake Manifold of the car.
8). Two vacuum line hoses, 4.0 feet each. (DO NOT CUT THOSE ANY SHORTER, IT'S ONE OF THE SAFETY FEATURES IN THE SYSTEM!)
9). One 5 foot length 3/8" Fuel Line (Needed to install the PCV Enhancer).
10). One 6 foot length Fuel Injection Hose (Needed for Fuel Heater Installation.)
11). Installation hardware: Bungee cords, cable straps, etc...
12). Catalyst (sometimes called “Electrolyte” but actually the electrolyte is the correct term for the catalyst PLUS water) – this is the very SAFE household Baking Soda: the typical kit should have a bag of catalyst to get you started. It completes the kit to be ‘Just Add Water.’
The typical bag is 4 oz and is enough for 6-10 months of normal driving, and more can be obtained cheaply at almost any grocery store in the world.
