    Rated 5 out of 5 by from This is the wideband to go with! After messing around with an innovate wide band I decided to go back to an Aem. Great wideband and easy installation.

    Rated 4 out of 5 by from Must have for forced induction cars.. except No doubt it's a great product for the money but AEM needs better tech support. They need to follow examples of Jegs Tech support which is one of the best in the business. AEM support are not the friendliest if you have issues you may need their help with. Installing this wideband is not for the beginners.

    Rated 1 out of 5 by from STOPS WORKING AFTER 5 MINUTES, Not once, not twice I had bought this to replace my 30-4100 after 7 years of service. since my 4100 finally met its demise after running Leaded Race fuel last year (my fault) I had to upgrade to this 30-4110 kit. Car was tuned in perfectly April this year. It was on way home from track of testing and tuning that my 4100 failed by reading "Full lean" [---] at all throttle positions. I broke down and bought the 4110. IT failed almost immediately, right out of the box. I returned it to Jegs and got replacement. The replacement failed, right out of the box. I returned that straight to AEM and had warranty claim submitted and resulted in faulty heat driver or something like that. They sent new one to me, no problem. Guess what, the new one failed after 5 minutes so I sent it back to Jegs and got another replacement. Got that installed, it gave me reliable readings for 20 minutes, same readings I had 2 months prior with my 4100 at the track. Those readings however turned full lean once again. At this point, I have given up on this 30-4110 kit. Returned to Jegs, I cannot deal with any more let-downs with replacement gauges. The spark plugs in my car are a nice beige color, I hear no "lean popping" and the car has phenomenal acceleration. The car is not the problem.

    Will this AFR gauge work with leaded gas?

    Asked by: Hotrod1988
    Yes, but only for a short period of time as leaded fuel will contaminate the sensor.
