Great product, better pricing then competitors and easy to install

Very fast delivery, packaged was perfect, all parts were correct and finally, The PRICE was perfect!

I have been looking for a AEM wideband AFR gauge for a while now and i finally saw this on Amazon for an awesome price

Great item works really good easy install also super easy

This is one of the best items on the market at this time.

Great service, fast shipping item was easy to install and looks and work like it should.

Packaged very nicely and product is of strong quality, looks exactly as it does in the image

, sensors are obviously not manufactured well nor quality tested

Horrible product expected much better quality and thought it would last at least a month

I love AEM products as they are very good quality, well built products which will last years.

Good quality, easy to install and comes with a sticker that gives your an extra 25kw!

Installation was painless and took roughly 20 minutes since my downpipe already had a bellmouth o2 bung

Installation was very easy and love not having a recalibration every 6 months

Excellent instructions, easy installation, functions perfectly- nice and steady reading but very responsive to changes in RPM or mixture adjustments

Installation was straightforward and easy except for the firewall routing

Installation is very easy, and package contains everything needed for the installation.

Both times the gauge worked for a while displaying normal readings then suddenly started to creep lean until it would only register - - - on the gauge face

The first kit I received the gauge worked until the car warmed up

Gauge works fine for around a month then the sensor failed reading full lean at all times, contacted eam but the way the warranty works I opted to buy just a new sensor and installed it, again one and half month later and sensor is shot again, this is so

Gauge works fine but came with a faulty sensor doesn’t work

Worked as it should, helped me tune my 300C to the perfect spot I want.

Awesome, price way better than summit, slow free shipping

Love the fact that it does not need to be calibrated in clean air like some others.

I like the fact that it has a serial data and a 0-5 volt wire for datalogging.

The 4 face configurations is really neat and love the fact it came with white ones to match my interior (as shown, sorry for the crappy panoramic photo)

I like the fact that in one day I was able decide on the best overall best product and I received quickly

I also like the fact that it has an auto dimmer, bright in the day and gets darker at nights

Full on authentic AEM wideband with all required hardware and parts

A good wideband gauge like this is a must have for engine tuning and monitoring

It’s a fantastic wideband when it works, but aem will not send you a new replacement sensor and if you want a new one through amazon you have to send the whole kit back and get a new one

There is no more reliable consistent wideband gauge, ask any tuner

Before I bought this gauge, I tried to save some money by purchasing a cheap eBay APSX wideband

and id really like to have a working afr gauge since i paid good money for it

I get.2nd Update: I contacted Amazon and they agreed to refund my money

They did not refund my money or respond to further emails about the issue when I asked them to explain themselves or offer me a 'good' o2 sensor if they were going to insist every one I bought was bad

do not waste your money on these broken unitsinstead goto plxdevices and order a good stand a lone AFR gauge kit

The first kit I received the gauge worked until the car warmed up

Like every other bad review got the kit and right out of the box the gauge pegged lean and didn’t move

do not waste your money on these broken unitsinstead goto plxdevices and order a good stand a lone AFR gauge kit

The kit also comes with several butt splices although one would suffice

I warranty the kit to AEM, the kit I got from them worked flawlessly

Gauge works, lights up and all that, but came with a bad sensor.

My sensor that was provided was working for about 30 seconds then completely died

Used for a day and the sensor went bad, got a replacement for AEM and same deal

then after about 6 miles of driving the gauge just started showing --- seems this sensor has failed as well

The advertized that it came with a genuine Bosch sensor.

Pretty sure the sensor is a fake, bosch o2 sensors have the part number on the connector and say bosch on them somewhere

The kit arrived with a damaged O2 sensor that will cost $80 to replace

Looks like it originally had a cheap knock off O2 sensor which failed pretty quick

each time.now it seems I have a bad O2 sensorI was told to go buy a new

Never worked, bad o2 sensor with either too lean at idle (afr +17) or too rish with boosting (afr 10 and below)
