        1 2018 GT - Tolliver Installation Time: Less than 1 Hour

        pay more or same for less

        On my two previous mustangs I have had the Airaid...always loved the designs, especially the option to have an open box or closed because works well with air ram hoods. Honestly I gotta say this was the first ever product for my stang i opened and wasn't enthusiastically installing; seriously. The size of elbow tube seemed small compared to past design. The fittings are plastic versus the aluminum fittings of the past. Directions are awful; details please (and I've installed enough of these to not need them but for a newcomer directions needs those details). The coupler's width is short so it leaves a gap after install. The build seems lesser compared to past ones; the feel and look of texture and molding process seems lesser compared to competition. I had an injen intake and quality, fit, and build was on spot but and a closed box design, which I am not a fan of, but i ultimately switched to airaid because it was familiar. So after all that the price seems too much seeing that you pay more or same for less.

        1 2019 GT - Tonio6453 Installation Time: Afternoon

        Great product horrible delivery

        I was excited to order this part as I had an air raid intake on my 11 5.0 Upon receiving the order and after tear my car apart to install new intake, I found I was missing two crucial pieces that connect two other hoses from the engine. Half my mistake since I didn’t check everything was in the box first but bigger mistake from manufacturer as they did not deliver everything as they should. Quick stop at nearest part store and luckily i was able to find a suitable replacement for the missing pieces

        5 2019 GT - WhitePonyGT Installation Time: Less than 1 Hour

        Airaid CAI

        Super easy install and looks good under the hood. Sealed nicely for minimal heat soak. Do not have to butcher the engine cover like the Roush CAI. Used dry filter opposed to wet due to ease of maintenance. Decided not to risk voiding warranty and went with a non-tune CAI. Noticed a slight difference in sound and performance. Actually hisses a little while slurping air, sounds nice. Airaid says 17hp increase. The only challenging part is deleting the entire sound tube because the nut on the firewall is tedious to remove. You can halfass it by leaving some of the sound tube and cap off remaining section if you don’t have the patience.

        Very Easy Install

        This installation went incredibly fast! I DO notice a pickup increase. Although a tune is not necessary, I would recommend a tune for increased performance.

        Air raid cold intake

        Very easy to install. I just put on so I haven’t had time to see any performance or gas mileage gain yet. I go look good under the hood

        Nice cold air intake

        The fit and function of this intake is absolutely perfect. The instructions are a little bit hard to follow but if you've installed any intakes before it's pretty straight forward. The main thing you need to watch on this is the placement of the sensor. Easiest way to make sure you have in the right direction is on one side of it there is a red clip that locks the plug in place. Make sure this red piece is facing up and you've got it positioned correctly.

        5 2018 GT - Andi Installation Time: Less than 1 Hour

        Perfect Intake for the 2018 Mustang GT

        Install was easy, car sounds great, runs great and best of all no tune needed. I do feel slightly more power. Just be careful to install the Mass Air Inflow Sensor the correct pointing way or else the car won't start :). I had installed it upside down fyi. As the other review mentioned, the instructions aren't clear, and the MAF sensor can be installed both ways but the car only runs if the sensor is facing correctly.

        Great product

        The intake it's self is a great product. Well made and the fit is perfect. Only gripe I have is that the instructions are not good at all. No details on what size allen keys to use on which screws or which way to orient certain fittings. As someone who's done lots of work on cars over the years I was able to figure them out easily but someone new to working and upgrading cars may have trouble or may install fittings incorrectly the first time. Other than that the intake has been great. Noticed a slight increase in sound and acceleration. Install took under an hour if you don't include trying to remove the sound tube.

      I have a 2018 mustang gt with active exhaust system. Will this have check engine light after installing it? My friend told me that his car will not start and basically on limp mode after installation. Please advise. Thank you.

      • Installing this intake should not cause a check engine light as it will not require a tune.

      Does this have a removable MAF insert like on the Roush CAI?

      • This will only perform to the best of it's abilities with the MAF sensor installed.
