AEM Wideband sensor and gauge
The AEM wide band lambda is the most popular gauge on the market. Maybe because it is so easy to install and use? Quality and function are the two biggest advantages of this gauge.
Technical information:
- 0-5V output for eg aftermarket ECU
- Complete with probe, wiring and lambda nut
- 6 in 1 gauge - 3 dials and two different gauge rings included to make it all match your interior.
- Accuracy: +/- 0.7%
- Consumption: 1.3 A
- Measurement range: 0.751 -> 1.143 Lambda 10.0:1 -> 18.5:1 AFR
- Sensor: Bosch LSU4.9
- The guge is delivered with sensor and wiring - you don't have to connect to a computer or ECU.
- If you want to log the values via ECU or or computer, this is possible.
Outputs:
- Analog 0-5V
- Serial output for connection to eg com-port for data logging.
- Length of sensor and cable: 60cm
- Extension cable length: 3.6 meters
ATTENTION! Be sure to read the manual before installation!
Installation:
NOTE
- The probe must be mounted at least 18" (45cm) from the turbo
- The probe must be mounted above horizontal position.
- The probe must not be installed without voltage supply from the gauge
Installation of the lambda probe in the exhaust system:
TIP!
If the display shows three lines, it means that the lambda sensor presents values outside the display value. Then mount the lambda sensor in the exhaust gas flow if this has not already been done. Step two is to replace and test with another lambda sensor to get a value.
Information that applies to all lambda probes regardless of brand and especially broadband lambda:
- The sensor contains a "ceramic" part and is therefore sensitive to shocks and extreme fluctuations in temperature
- The sensor is not made to be used with leaded fuels. It works but will have a shorter lifespan
- using rich fuel mixture shortens the life of the sensor (Lambda < 0.95)
- Exhaust gas temperatures above 850 degrees shorten the sensor's lifetime
- High engine oil consumption shortens the life of the sensor (1 liter / 160 kilometers)
- With the lambda probe installed in the exhaust system. -Do not start the engine without applying voltage to the meter and connecting the lambda sensor to the gauge

“After trying a few better known brands such as Tilton and Extreme, and never being super happy... Conor was able to recommend me the perfect clutch for my application... I havn't broken any drivetrain parts since I installed it.”

Tell us the car. We will spec it.
Chassis codes, spring rates, angle kit clearances, clutch ratings. Send us the car and what you want it to do. The answer comes from someone who has run that setup, not someone reading a product sheet.

Ordered before 1pm, fitted this weekend.
In-stock parts ordered before 1pm are dispatched the same day. UK and Ireland typically arrive next morning, worldwide as quick as three days. Times do vary, but that can mean the part is on the car within a few days and she is back out blasting the roads by the weekend.

Straight answers
The questions you were about to open a chat about.
How do I know it will fit my car?
Send us your chassis code or your reg in the chat and we will confirm before you spend anything. If you order and it turns out to be the wrong part, we swap it.
“Had a mix up with the item description (order wrong part) they was quick to email me and see what part I was meant to order and substituted it for no extra cost!”
Bradley Page, verified customer, 31 Jan 2025
When will it actually arrive?
In stock and ordered before 1pm, it leaves the same day. UK and Ireland is usually next day, occasionally 1 to 3 days. Europe 1 to 5 days, rest of world 3 to 5 days on express.
If something is not in stock, we will email you right away with an ETA and any available substitutes. On the rare occasion it does not work out, we will happily refund your order.
Will I get stung for customs or import VAT?
No. The price you pay on our website is what it will cost to be delivered to your door. You will not receive any surprise surcharges after ordering.
What if I change my mind?
30 days on all stock items, full refund on the parts. If you ordered the wrong thing we will help you get to the right one for as little money as possible. We have been there.
What warranty do I get?
Everything on our website is covered by the standard manufacturer's warranty.
If you ever need to claim, we fight your corner. We will do everything in our power to make sure you are looked after, rather than leaving you to argue with a manufacturer on your own.
Can I pay it off over a few months?
Yes. Klarna and Shop Pay Finance are both at checkout, so you can spread it without putting the build on hold.
Can I just ask someone what to buy?
That is the bit we are actually good at. We run our own race team and workshop, so you are talking to someone who has fitted it, broken it, and fitted it again. Hit the chat and tell us what the car is doing and what you want it to do.
