What’s Included in the Kit

• StP Gold (vibration damping) – reduces metal resonance and engine vibration noise
• StP Accent 10mm (sound absorption & heat insulation) – absorbs airborne noise and blocks heat transfer

This combination creates a complete multi-layer soundproofing system for your bonnet.

Key Benefits

• Noticeable reduction in engine noise inside the cabin
• Quieter and more refined driving experience
• Reduces heat from the engine bay and sun exposure
• Improves thermal stability of bonnet and components
• Significantly better than factory bonnet insulation

Why This Kit Works

Most factory bonnet insulation is thin and low-performance. This kit uses a professional multi-layer approach:

• Layer 1: StP Gold – controls vibration and metal resonance
• Layer 2: StP Accent – absorbs noise and reduces heat transfer

This means you are treating noise at the source, not just covering it.

Engine Noise Reduction Explained

Engine noise travels through metal panels and enters the cabin. By damping vibrations and adding an absorption layer, this kit:

• Reduces high-frequency engine noise
• Improves insulation between engine bay and cabin
• Creates a more premium driving feel

Installation Guide

• Clean and degrease bonnet surface thoroughly
• Apply StP Gold first (vibration layer)
• Install StP Accent 10mm on top
• Use a roller for proper adhesion
• Ensure full coverage and contact

Installation time: approximately 1.5–2 hours DIY

Who Is This Kit For?

• Daily drivers looking for more comfort
• Performance cars (reduce engine noise)
• 4WD and touring vehicles
• Anyone upgrading from factory insulation

Why Choose This Kit Instead of Buying Separately?

• Pre-matched materials for best performance
• No guesswork on layering
• Better value than buying components individually
• Tested in real workshop conditions
