Review & Installation Video

Review & Install Video

Hey, guys, Stephanie with, here with an overview and install of the C&L calibrated street performance mass air flow that's available for all 2015 and newer GT Mustangs. In this video, we're going to be talking about what exactly this piece is and how it can help your GT, and of course, we're going to go over the install, as well. I'll get into more detail later, but the install for this is a simple one. It's a one out of three wrenches on the difficulty meter. The C&L calibrated street performance MAF is gonna be for those S550 GT owners out there, that are looking for a fast, easy way to pick up a few horsepower without voiding their warranty. We all know that a tune is a very easy and effective way to pick up horsepower on any Mustang, but the dilemma is always centered around the warranty. This MAF does open up some restrictions around air flow in the factory programming of the ECU like a tune would, but it most certainly is not going to void your warranty, and I'll explain how. So, this is a MAF sensor replacement that has a calibration on it. Now, this is a custom calibration that has very specific and tight spec ranges, especially at points close to idle and wide-open throttle, and each sensor is going to include calibration seats that will detail the specs, just so you guys know. The difference between this custom calibration and the custom calibration that you'd receive with a tune is that this calibration doesn't override what's already on the ECU. An aftermarket tune totally overrides all factory calibration, which is why it voids your warranty. This calibration, on the other hand, simply provides the ECU with a wider range to read airflow, and moves the existing sensor's ability to read the range of airflow, which is how you're going to see throttle response improvements, gas mileage improvements, and even some small horsepower gains. You're specifically going to see improvements from 2,000 rpm to red line. And, this can be paired with a stock air box or an aftermarket one, so if you already have an aftermarket cold air intake, you don't have to worry about that. Another thing that I wanted to point out about this sensor is that it is a direct plug-and-play replacement. This just replaces your factory mass air flow, which is going to make the install, if you even want to call it that, beyond simple. When it comes to price, you can expect to pay right around the $300 mark for this MAF. Now, it's hard to compare this price to anything else since this is a unique product, but again, the highlight here is that this isn't going to void your warranty, but it is going to open up some similar benefits to you like a tune would. So, this offers a good workaround if you're looking to improve performance and keep your warranty on your new car. As far as the install goes, I said this earlier, but it doesn't get much easier here. If I have to even rate this, it's a one out of three wrenches on the difficulty meter, and it installs in less than 15 minutes. Since this is a direct replacement, all you have to do is unplug your factory MAF and plug the new one in, and the install is complete. Wrapping things up here with the C&L calibrated street performance mass air flow, this is a direct MAF replacement that comes with a custom calibration that's going to open up the reading range of the factory ECU's settings. This will provide you with some benefits that are similar to a custom tune, but it isn't going to void your warranty, which makes it a perfect option for those of you out there looking for performance gains, but that still want to hang on to that warranty. As always, I suggest you check it out more online, and for all things Mustang, keep it right here at

Calibrated for Performance. Did you know that your Mustangs factory Mass Air Flow (MAF) Sensor could be robbing you of power? Well, it's true. Put simply a MAF Sensor is designed to read the volume of air flowing into your engine. The problem is that the factory MAF Sensor is limited to how much air it can actually read and will "peg" due to increased air flow. However, C&L's MAF Sensor has been custom calibrated and scaled to accurately read the higher volume of air created by aftermarket bolt-on's like cold air intakes and force inducted setups to ensure peak performance.

Performance and Power. With an unmistakable improvement in airflow, when compared to the stock sensor, you can expect to see increases of 10 to 18 horsepower with an increase in performance starting at 2000 rpm's all the way to red line. By upgrading to a C&L Performance Calibrated MAF Sensor you will not only see an improvement in performance and power, but you will also see an increase in throttle response and fuel mileage.

Plug-N-Play Installation. Engineered to be a direct fit plug-n-play replacement for the original stock sensor this C&L Slot-Style MAF Meter installs with just basic hand tools. No extra modifications are required for an easy 15 minute installation. All necessary parts and instructions are included.

Application. This C&L Street Performance Slot-Style MAF Sensor Meter is specifically designed to fit 2015 to 2017 GT Mustang models equipped with the Coyote 5.0L 4 valve V8 engine.

Does this work with vpm supercharger tune?


  • The C&L Street Performance Slot-Style MAF Meter / Sensor can used be used with an aftermarket tune, however, we would highly recommend getting a tune with the meter/sensor for proper functionality.

Does this meter void the factory warranty?


  • Unfortunately, we would not be able to guarantee that the C&L Street Performance Slot-Style MAF Meter / Sensor will or will not void the factory warranty. I would highly recommend speaking to the general manager and shop manager of your specific dealership on whether this aftermarket part will void your warranty.

Does this work with the handheld SCT programmer's if your car already has a tune with your factory MAF sensor?


  • The C&L Street Performance Slot-Style MAF Meter / Sensor does not require a tune,as it is a direct replacement, however, if you have free tunes for life, if would be beneficial for a tune revision.
