Aem afr gauge
Great kit, easy to install if only using the gauge for afr as it's just power supply wires needed. It is not recommended to cut down the sensor harness, bit rubbish as there is way too much for a motorcycle install. Also nowhere in the description does it say not waterproof!! Even the aem website says good for cars or bikes. Only after I installed the thing did I get to the part where it says the gauge will fail if water gets on/in it!!! What the fudge, that should be a big point to let prospective buyers know. Now gotta work out how to tuck it somewhere dry behind the fairing screen. I bought this to replace an innovate lm1 that had a failed sensor, that was waterproof and worked fine on the bike for 3 years.

the best wideband around
simply put, the best wideband in the market. if you have a tuned car and you can afford it, just buy it! monitoring your mixture is crucial, and no other gauge does this more precisely and responsively than the new x-series. according to my tuner, who monitors mixtures using super-expensive and complex equipment, my aem gauge readings are absolutely identical to his, without any hint of delay. also, based on his experience, this x-series outperforms the innnovate wideband, which is also considered top class. on top of it, it's very compact, stylish, with clearly visible readings under any condition. so, 'why 4 stars instead of 5', you might wonder.. well, it's because of the bosch sensor that's included. these sensors are used by almost every top company, but have a nasty reputation of failling on highly tuned setups. mine failed within a year and aem's guarranty didn't cover it. I replaced it with a much cheaper one and all was good again :) Read full review

Great product
Works just fine, really almost plug and play (just welding of the lug onto the exhaust). Very fast update, really too fast to see, but used in a control system, just perfect.

Quality original AEM product.
Quality original AEM product. useful fitting guide and clearly well liked by many enthusiasts with a wealth of video guides on installation online. Should help with "road tuning" and avoid damage to your engine used correctly.
