EFIE

EFIE, Stands for Electronic Fuel Injection Enhancers.

When we add HHO gas to our engines to burn our fuel more efficiently, by increasing combustion, we are adding more oxygen in to the air/fuel mixture.

This changes the exhaust gases and tells the computer through the oxygen sensors something is not right. The computer will try to adjust the air/fuel ratio by adding more fuel.

The Electronic Fuel Injection Enhancer then goes to work to resolve this, by altering the signal to the computer through the oxygen (O2) sensors, so the computer will be content with its readings.

Which O2 Enhancer Is Right For My Car?

Essentially There Are 2 Types Of Oxygen Sensors;
Narrow Band And Wide Band

If your vehicle is pre 1997 then it is a narrow band.
If it is an American car, then it is a narrow band (a few 2009's are wide band).
Japanese or German vehicles built after 2000 is most likely a wide band.
If you have 4 wires (and it is not a Toyota) it is a narrow band.
Toyotas have 4 wires and they are wide band.
If the sensor has more than 4 wires it is a wide band . So 5 and 6 wires are wide band.
Most diesels will not have O2 sensors, however a few do.

* Look for a sticker underneath your hood with technical data about your vehicle. If you have wide band oxygen sensors, which may be called AFR (Air/Fuel Ratio) sensor, they are noted on these stickers.

How Many Oxygen Sensors Do I Have?

V-6, V-8 and larger will usually have 2 oxygen sensors that are upstream of the catalytic converter, one on each exhaust manifold. Vehicles with 4 cylinder engines usually have 1 upstream sensor. You may find a configuration that varies from these.

Not Sure Which One You Need?

It can get confusing. If you are not sure which one is right for your vehicle, simply fill out our request form at the bottom of this page and we will get you an answer very soon. You may find that your vehicle's year, make, model and engine size has already been requested, check below the request form.

All products come with great instructions, even though it may seem intimidating at first. Once you get it dialed in, thats it, you are on your way to experience an increase in your mileage.

Digital EFIEs For Narrow Band Oxygen Sensors

We recommend Digital Electronic Fuel Enhancers for all narrow band oxygen sensors. These new digital enhancers allow much leaner settings than other O2 enhancers.

Can make the air/fuel mix much leaner than earlier designs. With this device you can lug down your engine, and often kill it if you set it too lean.
Absolutely rock steady adjustment no matter what temperature the environment. Will vary less than 1/2 of 1% over it's rated temperature range of -40 to 125 Centigrade.
One adjustment pot modifies both upstream (Digital) O2 Enhancers equally, and similarly, one pot adjusts both downstream (Analog) O2 Enhancers. This makes these devices easier to set.

Quad Digital EFIE Basic

This unit is recommended for almost all American cars, foreign cars older than 1997 and most foreign cars after 1997. Quad Digital EFIE It will be the right one for 90% of all vehicles.

$99.00

Dual Digital EFIE Deluxe

These should be used for oxygen sensors that are upstream of the catalytic convertor. Digital EFIE Deluxe If you need to treat down stream oxygen sensors please purchase the Quad Digital Enhancer above.

$99.00

EFIE's For Wide Band Oxygen Sensors

This is what you need for all 4 and 5 wire oxygen sensors, there is a variation of the 5 wire sensor that uses 6 wires, this unit will work with these also. Wide Band EFIE At this time it is only avaliable in the dual. If you have a single, you will just not hook up the second circuit.
