Tired of your Land Rover boost hoses going soft, ballooning, or splitting under pressure? 🚙💨
Ordinary silicone handles heat well, but it hates oil. The constant fine oil mist from your crankcase breather and turbo slowly soaks into standard hoses, turning them soft and spongy from the inside out.
Enter the Pioneer 4x4 Fluorosilicone (FSH) Lined Silicone Hose Kit — engineered specifically for the harsh, oil-laden air of Land Rover diesel and petrol engines.
Why Choose Pioneer 4x4?
Genuine Fluorosilicone (FVMQ/FSH) Liner: Stops oil absorption at the source, preventing the hose from softening, swelling, or blowing off over time.
Tough 4-Ply Construction: Polyester-reinforced with a solid 5.0mm wall thickness, manufactured to strict SAE J20 R4 standards.
Extreme Temperature Range: Performs reliably from a frozen -50°C winter start straight through to +180°C of sustained under-bonnet and boost-pipe heat.
Complete Ready-to-Fit Kit: Includes every hose for the application plus premium stainless steel Mikalor clips with collars.
Whether you’re daily-driving a Defender or prepping a Discovery for serious off-roading, upgrade to a hose kit that’s built to outlast the vehicle.
🛠️ Precision engineered by Pioneer 4x4.
