NA Motors Phantom horn button is simple, clean and designed to sit perfectly flush with your steering wheel.
A subtle trumpet engraving adds a elegant touch without drawing attention.
Phantom is named for its slim, nearly invisible design that merges with the steering wheel.
The top plate is made from POM (Polyoxymethylene) instead of aluminium, giving a softer, more comfortable push, reducing vibration and preventing the cold, metallic feel that aluminium can have on the hands.
NA Motors Phantom horn button is available in two thickness options: 4 mm and 5 mm. Installing the wrong thickness may cause the button to sit 1 mm recessed or protrude 1 mm from the steering wheel. Please measure your steering wheel carefully and choose the correct option. If you cannot measure it yourself, please contact us before purchasing and we can help determine the right size for you.
The package contains the horn button and six (6) prolonged bolts (M5 x 16mm) for mounting it on your steering wheel/boss kit.
Made in Japan.
Features:
- Sits flush without a spacer, matching your steering wheel thickness.
- POM top plate provides a smooth push and a seamless gap with the wheel.
- Metal compression spring gives a solid, reliable push without using rubber.
- Slim 6.5 mm base with invisible creates a minimal look.
- Weather-resistant anodising keeps the horn button looking its best over time.
