Cadillac CT4 Accessories: Upgrade Your Entry Luxury Sedan

Introduction to The Best Cadillac CT4 Accessories

The Cadillac CT4 is the basic model of Cadillac’s current sedan models. It has a compact car body and rear-wheel drive. There are several kinds of trim levels, including the everyday Sport. Another model is the CT4-V Blackwing with track capability. The CT4-V has a 472-horsepower twin-turbocharged V6. Although the CT4 is the entry model in the Cadillac range, it is still a high-class vehicle. People like the design of a driver-focused interior and sharp outlook. CT4 owners want to upgrade to make it personal. So they are looking for many ideas to improve CT4’s appearance, which is already special. The following are the best Cadillac CT4 accessories you can find in 2026.

Exterior Upgrades

CT4 LED Light Up Emblem

The LED Cadillac CT4 light up emblem can fit well with the CT4 grille mounting system. The designer used aluminium as the CT4’s housing material so it looks quite premium. The white LED lights will turn on as soon as you start the ignition. You do not need any switches or timers, and the process is fully automatic. You can own it for $159.99. CT4 owners usually prefer this accessory because they can see the most beautiful effect at a reasonable price they can afford.

There is an important note for CT4 owners: Some CT4 Sport and Premium Luxury models have the Driver Assistance Package. So you will find an Adaptive Cruise Control (ACC) radar sensor behind the front grille emblem. If your CT4 has adaptive cruise control, you should contact us before ordering. We can help you confirm which one is suitable for your car.

CT4 Puddle Lights

Cadillac puddle lights can fit perfectly with the CT4 door mirror housing. The CT4 has a compact body shape. So you will find the Cadillac logo projection closer to the door entry point. But this actually creates a tight and clean puddle light effect. After that, you can still see a good effect when you park the car in the parking space. You need about 10 minutes to install each side. You don’t require any other tools.

LED Door Sill Lights

You can install Cadillac LED door sill lights on four CT4 door sills. Every time you open the doors, the Cadillac letter lights will light up. You will find the lights work more effectively on the CT4 because of the car’s sport feature. Drivers and passengers can see the dynamic effect at once when they get in or out of the car. Full fitting instructions are available in our door sill installation guide.

Floating Center Caps

People can add Cadillac floating center caps on the CT4 wheel hubs. The CT4 usually has 18-inch wheels in the standard model. The Sport or Blackwing models often have 19-inch wheels. The caps can keep a level position at any speed during driving. You can see the effect obviously for both wheel sizes. You don’t need any battery, and the caps can resist corrosion. The selling price is $99.99.

Interior Upgrades

Crystal Shifter Knob

The CT4’s centre console is an important part of the whole interior. The centre console is narrow, but drivers can touch it easily. The gear selector plays an important part in the centre console. The factory shifter works well but looks too common. You can install the LED Cadillac crystal shifter knob to improve the interior ambient system. Passengers will have a deep impression on the crystal glass material without doubt. This is one of the most worthwhile upgrades you can make to the CT4.

LED Cup Holder Lights

LED Cadillac cup holder lights can be perfectly put into the CT4 centre console cup holders. You can charge them with USB without installation. You will see a Cadillac logo shine softly in the cup well. The selling price is only $29.99. Most people can afford it, and it is almost the cheapest upgrade on this list. We believe that other passengers will praise for this change when they get in your car.

Floor Mats

These Cadillac logo floor mats are well designed for the CT4. They use a double-layer waterproof design to protect the factory carpet. The CT4 is a sporty vehicle. It means the driver-side carpet is more likely to wear out over time. So you can buy floor mats to protect the area at first, and this will not disappoint you.

Memory Foam Seat Cushion

The CT4 sport seats can support drivers’ bodies well. But they are firm, especially in V-Series models. During long trips, you can feel more comfortable by using the Cadillac memory foam seat cushion. There are two colors for you to select: black and brown leather. You can also see a Cadillac logo clearly on the surface.

Gold Emblem Decal

For people who want a quick exterior upgrade and don’t want to use tools, the Cadillac gold emblem decal is the best choice. You can use it to cover the front or rear CT4 badge, and then it will appear gold. You need about five minutes to finish the work. Also, you can receive a better effect if your CT4 has a dark paint finish. One day, if you don’t want it anymore, you just need to take off the decal.

CT4-V and CT4-V Blackwing

All accessories in this guide are suitable for CT4-V and CT4-V Blackwing models. Although the Blackwing has a wider car body, it will not affect the function of any products listed—including the emblem, mirror, sill, and wheel hub.
