      Review & Installation Video

      Hey guys, Stephanie with, and this is my overview of the RTR Grille with LED Accent Vent Lights that's available for all 2015 or newer S550 Mustangs. This overview is gonna cover a few topics with the RTR Grille, like the different options with this Grill as well as the install. The install for this one is a simple one. It's a one out of three wrenches but we'll talk more about that later on.The RTR Grille with LED Accent Vent Lighting is gonna be something that an S550 owner should check out if they're looking to do something a little bit different styling wise, or if they're just looking for some of that RTR statement styling. I mentioned some options earlier and I wanted to explain that before I got into any details with the grille. There a few different ways that you can purchase this grille. You can purchase just the upper with the lights, just the lower, or a combo of the upper with the lights and the lower so you match all the way around and complete the package. There's another option too which may be very good news to some of you. You also have the option of purchasing just the lights if you want to. If you've already purchased the RTR Grille without the LED lighting, you can just pick up the lighting and complete the look. This is the same upper grille with accent LED lighting that's included as original equipment on the RTR Mustangs. You can see it's the same three window design and it's gonna eliminate the stock pony that's normally in the grille. Both the upper and lower grilles are complete replacements of the factory grille, not overlays, and they're both actually gonna help increase some airflow to the ride if you compare them to the stock grilles. Getting into the LED accent lighting some more, obviously, there's gonna be lighting around the vent openings and the accent lights are gonna plug into the factory headlight harness. You won't have to cut or splice, but i'll get more into the install later. Plug in the accent lighting into the factory harness means that'll be automatically activated with the daytime running lights. If the car is on, the accent lights will be on. This grille is gonna work with the stock front fascia, so it'll work for the V6, the EcoBoost, and the GT as long as you have the stock frontend. One thing that I did wanna note though, is that the lower grille, just the lower, is not gonna work on cars that have the Adaptive Cruise Control. This is because the control is mounted in the lower grille and the RTR Grille would interfere with it. When it comes to price, it really all depends what you end up looking for. The combo kit of the upper with the lights and the lower grille together is gonna cost pretty close to the $750 mark. If you wanted just the upper grille, that's about $550 by itself and about $200 for just the lower grille. The lights by themselves are gonna cost close with the $300 mark, so it's safe to say that you definitely save a few bucks by purchasing the kit and then if you wanted to purchase just the light, you're gonna be paying a pretty penny for them.The install here isn't easy one. It's a one outta three wrenches in the difficulty meter and the time for the install will change a little bit depending on if you're installing both the upper and the lower grille, or just one or the other. Assuming that you're installing both, I'm going to say that this will take about two hours to complete. You will need to drill in a bit to drill up three mounting holes for the lights in the grille and that's really easy and simple, so nothing you have to worry about. If you want, you can start by getting the RTR grille ready to install. You drill three mounting locations for the accent lights, but RTR has the locations pre-marked for you already. The accent lights are held in by the supplied hardware and then you'll need to mount the control box to the backside of the grille. There's double-sided tape on the back so it just sticks in a place. You will need to remove the front fascia to complete the install. You just want to jack in some stands or lift to elevate the car some. Removing the front fascia isn't hard. There are a lot of clips and some screws that hold it into place. The fascia will then just pop off and you pull the sides near the headlight. Getting the top factory grille out isn't as hard as you might think it is. There's a soft gasket that comes out with the screwdriver, and then you can remove the plastic clips that are along the edge, the new grille will pop into place using the supplied hardware from RTR and then the center bumper soft gasket goes right back in after the new grille. To integrate the lights, you just need to unplug the headlight harness from the back of the headlight, plug the supplied harness into the headlight, and then piggy-back the factory harness on to that. You might need to tuck the harness up into the frame rail to keep it all up and safe, and that's all it's gonna take. Wrapping things up here with the RTR Grille, this is the OE Grille for the RTR Mustang and it comes complete with the LED Accent Lighting around the vents. The lighting is completely plug and play and the accent lights will illuminate when the car and the running lights are active. This is very easy to install.

      Ready To Rock! Now you can add the same exact Upper grille with LED accent lighting that was featured as original equipment on the RTR Mustang to your very own late model muscle car. This Replacement grille was designed and developed with input from Vaughn Gittin Jr. to give your S550 Mustang an aggressive race inspired appearance that looks awesome on and off the race track. If you're looking for a way to set your Pony apart from the rest of the herd, this RTR grille is for you.

      LED Accent Lighting. The RTR Upper grille is available with the very popular integrated LED Accent Lighting around the vent openings for an impressive head turning appearance. The LED Accent Lights simply plug directly into your Mustang's existing factory headlight harness with no cutting or splicing required. The LEDs are automatically activated in conjunction with your Day Time Running Lights, so they are always on when your Mustang is running. For those that would like the RTR Upper grille without the accent lighting, please see part# 389943.

      High Powered SMD Technology. The halo rings included with this RTR Upper grille utilize SMD technology to produce a super bright white light while only consuming 1/10th of the power of standard incandescent bulbs. These LED accent lights are rated at 100,000 hours of continuous use.

      Improves Cooling. Not only will this RTR grille add great aggressive styling to the front of your S550 Mustang, but will also help lower under hood temperatures. With decreased surface area, the RTR grille will allow for an increase in air flow across the radiator, when compared to the original factory grille. This additional air flow will help to improve engine cooling, which in turn will increase engine performance.

      Quality Construction. RTR designed their Upper Replacement grille using the original OEM CAD data from Ford to ensure a perfect fit. Manufactured from an OEM quality high pressure injection molded thermal plastic olefin (TPO) material, this grille is extremely durable and can hold up against the elements and the hazards of everyday daily driving.

      Straight Forward Installation. Designed to be a direct fit replacement for the original factory grille, this RTR Upper grille installs reusing the stock clips and mounting points. There is no cutting or modifications required for a clean straight forward installation. However, it should be noted that removal of the front fascia will be required for installation. Installation can be completed in about two hours with just basic hand tools.

      Application. This RTR Upper grille with LED Accent Lighting is designed to fit 2015-2017 GT, EcoBoost and V6 Mustangs with the stock factory front fascia installed. It will not fit Shelby GT350 models.

      Please Note. The RTR Lower grille is not included with this kit.

        Awesome upgrade!!!

        I purchased the RTR grill and I am happy that I did. This modification is awesome. With so many Mustangs out there this RTR grill definitely separates mine from the rest. I love the look it gave my mustang without changing it too much.

        Excellent Product and Easy Install

        RTR has done an excellent job with this product. It adds a unique accent to your vehicle while providing increased air flow to your engine - very cool. I will say that the install was somewhat challenging if you have access to minimal tools. If you have an impact drill, installation is much easier. I would also recommend asking a buddy to join you for help - this made all the difference.

        Smooth and Stylish

        Definitely helps your Mustang stand out from the crowd. Install is easy when following step by step, but a little time-consuming. Overall, a nice addition to the Mustang, but I feel like it is slightly overpriced.

        Love the look, but quality is lacking

        I LOVE this on my 2016 Black GT, however half of the driver side LEDs did not work. AM replaced without a hitch and sent me a new set of lights. Now one single LED is not working on the passenger side. I have already paid to have someone install this twice and refuse to do it again so I have accepted my one missing LED. When I talked to the specialist at AM he said this was a recurring issue with this part. I was hoping for better from RTR.
