      Video Review & Installation

      Justin: If you're a fan of chrome and you're looking to add some bling under the hood of that 2018 and newer Mustang GT, then you might want to consider adding the Modern Billet Chrome Oil Cap that we have here today. Now, the Modern Billet Cap will feature a solid billet aluminum construction along with that triple chrome finish all for right around 40 bucks. Installation, well, as you can imagine, is going to be as easy as screwing in a light bulb here, gang. So, figure softest one out of three wrenches imaginable and no more than a few seconds of your time from start to finish.So, this is one of a few different chrome under the hood accents, available from the gang at Modern Billet designed for the S550 GTs. Now, depending on just how much you like chrome, you could, essentially, go wild with the number of accents also available here on the site, or just keep things simple and add one or two tasteful mods at a time, that is entirely up to you. And hey, to get a better idea of just how these things look under the hood, and how much people have actually added, feel free to check out the customer-submitted images page on the product page. Always a great way to see what other Mustang owners are doing with their ride. And it will give you a better idea of how this and other chrome mods look under the hood.Now, as far as the cap itself up, you're gonna be looking at a complete replacement here gang, and not just some cheap plastic overlay that you might see with some other accent kits in the market. Materials, again, will be that 100% quality billet aluminum, which has been CNC cut into this retro shape that you have here. Finally, the cherry on top, if you will, will be that triple chrome plating process, which has then polished to an absolute brilliant shine. Cap does also feature the paint-filled etching on top for both the oil word and also for the 5W20 weight. But now it comes a time in the video where yes, we show you how to install an oil cap on your GT. Now I know this is definitely in floor mat territory, as far as install difficulty is concerned, but it's what we do here. So without further ado, check out our detailed walkthrough right now.Speaker: So, the first step of this install is going to be reaching into the front of the car, pop the hood open, and prop it up. Now that you're under the hood, you want to locate your oil fill cap, which is right here on the front of the engine passenger side and unscrew it, remove it from the vehicle. Once you got that out of your way, take your new oil cap, screw it back on just like that.And that's gonna wrap up this review and install of the Modern Billet Chrome Oil Cap. Thanks for watching, and for all things Mustang, keep it right here at
