Our CNG car and truck conversion kits are unique. Working with cutting edge software developer LPGtech, we have developed a CNG conversion kit designed for the American market. Each system is put together in the USA for our customers!

SkyCNG uses only the highest quality reducer, injector, and ECU controller. Our tuning algorithm is unlike anything you have used before. Fewer complaints, less warranty work, faster installs, and increased customer satisfaction are all benefits of the SkyPRO and SkyPRO-HD systems. Protect your shop brand and only use the finest systems from SkyCNG. Ask about PLUG n' PLAY wires!

The multi-stage CNG pressure regulator (aka "reducer") takes the high pressure CNG from the cylinder tank and then reduces it to a low pressure natural gas that the car engine can handle. This is a critical and expensive component of the CNG conversion kit. The SkyCNG regulator is made of the highest quality. When you reduce high pressure gas, the gas will be very cold as it lowers in pressure. Our regulators have an intake hose that pulls water/coolant from your engine's cooling system (which is hot of course), and then uses it to keep things from freezing up. SkyCNG regulators can reliably handle up to about 320 horsepower before requiring a switch to gasoline at high RPM. Over 320 HP and we suggest a our SkyPRO-HD kit so you will not experience a pressure drop. Be weary of other brands who tell you they only need a single regulator at this power... the system will run fine for a little while, but end up failing. Our HD kit is the only reducer on the market with these capabilities that don't ruin the system faster.

The ECU is the computer of the CNG kit. It is constantly communicating with your vehicle's computer, or OBD system. The SkyCNG system is state-of-the-art and sealed from weather and the environmental elements.

Our injector rails are what actually sprays the CNG in specifically metered injections into your engine.

The solenoid is an electronically controlled switch to cut on and off the flow of CNG. It is integrated into the reducer for easy installation.

The weather proof wiring harness is what connects the ECU to the fuel injection system. SkyCNG offers "plug and play" injector harnesses for fast and simple installation. No more cutting and soldering all those wires!

Also Available from SkyCNG:

• 20 feet of 6mm high pressure SEAMLESS STAINLESS STEEL hose for connecting the cylinder tank to the regulator- Add $35
• P36 Refuel Valve 3600psi (where you pump the CNG into) Additional $79
• Need SwageLok Valves or other Specialty Parts? We have accessories to make life easier!

These high-quality "bi-fuel" systems allow your current vehicle to operate on EITHER gasoline OR CNG fuel. You will have a switch on your dashboard that allows you to choose which type of fuel on the fly! No restarting. No engine stall outs. These CNG car conversion kits are very common in almost every other part of the world. As the United States becomes more accomodating of cheap, clean natural gas we will see CNG conversion kits go mainstream. The SkyCNG conversion systems are state-of-the-art, designed specifically for American CNG standards.

SkyCNG provides the high quality systems for long term reliability. Beware the bottom feeders. When our system is properly installed, the driver shouldn't tell a difference in performance, nor should they have a check engine light, for years to come! We have an article that explains the signs of a lesser quality CNG car conversion kit.

SkyCNG recommends you study up on your local laws before any type of car engine modification is made. We also suggest you be an experienced mechanic to install these CNG conversion kits. While these kits should contain everything you need, we cannot guarantee your vehicle type won't need special tools or need a couple extra parts. Since we don't install them, we also don't guarantee you'll do things correctly.

FIVE (5) YEAR WARRANTY! BEWARE OF HIDDEN COSTS: Please compare our CNG conversion kit components with the competition. You will see that our system is much more thorough and complete and our price really does include EVERYTHING.
