Stinger RKXHL Roadkill Expert Hood Liner Kit 12 Square Feet Engine Bay Heat and Noise Reduction
The RKXHL from Stinger is a Roadkill hood liner kit supplying one sheet with a total coverage of 12 square feet (32 inches by 54 inches) at a minimum thickness of 10mm. Designed for application to vehicle bonnets and firewalls, it reduces heat convection from the engine bay to the hood surface and engine bay noise entering the cabin. The self-adhesive sheet conforms to curved surfaces and can be cut to shape with scissors or a knife.
Product overview
Engine bay temperatures in performance and turbocharged vehicles can reach levels that heat the bonnet from the inside out, risking paint damage and accelerating hood deterioration over time. The RKXHL is designed to block the heat convection from hot air flowing around the radiator and engine bay from reaching the underside of the bonnet, providing a protective thermal barrier between the engine heat and the hood panel.
Beyond thermal protection, the RKXHL also reduces engine bay noise that enters the cabin through the firewall or bonnet, functioning in a similar way to the factory hood liner found in higher-end vehicles. The material is equally suited to firewall application in addition to bonnet use, and can also be used in non-automotive settings such as garages, sheds, and workshops.
Installation is straightforward. Remove any old hood lining material and surface rust, clean the surface with methylated spirits or wax and grease remover, cut the sheet to the required shape, peel the self-adhesive backing, and press into position. The material conforms readily to the curved shape of most bonnets and firewalls without requiring heat or specialist tools.
Features and benefits
Engine bay heat reduction: The 10mm thick liner blocks heat convection from hot engine bay air reaching the underside of the bonnet, protecting the hood from heat-related paint damage and deterioration, particularly in performance and turbocharged applications.
Engine bay noise reduction: Applied to the bonnet or firewall, the RKXHL reduces engine bay noise entering the cabin, delivering a quieter interior environment similar to the factory hood liner found in premium vehicles.
Firewall application compatible: In addition to bonnet use, the RKXHL is suited to firewall application where engine bay and exhaust heat enters the cabin, providing thermal insulation and additional noise reduction at that location.
Self-adhesive, conforms to curved surfaces: The self-adhesive backing allows direct application to the cleaned surface without separate adhesive. The material conforms readily to the curved profile of most bonnets and firewalls, and can be cut to shape with scissors or a knife.
12 square feet of coverage at 10mm thickness: One sheet measuring 32 inches by 54 inches provides 12 square feet of coverage at a minimum thickness of 10mm, suited to full bonnet treatment in most passenger vehicles.

Frequently asked questions
What is the RKXHL designed to protect against?
The RKXHL is designed to block heat convection from engine bay hot air reaching the underside of the bonnet, protecting the hood paint and panel from heat-related damage. It also reduces engine bay noise entering the cabin when applied to the bonnet or firewall.
Can the RKXHL be used on the firewall as well as the bonnet?
Yes. The RKXHL is suited to both bonnet and firewall application. On the firewall, it provides thermal insulation against engine bay and exhaust heat entering the cabin, as well as reducing engine bay noise transmission into the vehicle interior.
Is the RKXHL compatible with Roadkill Expert sound damping matting?
Yes. The RKXHL is a complementary product to Roadkill Expert. For firewall applications, applying Roadkill Expert to the metal firewall surface first and then the RKXHL on top delivers a more complete thermal and acoustic treatment. Contact us for guidance on the recommended installation sequence for your application.
How is the RKXHL installed?
Remove any old hood lining material and surface rust, clean the surface with methylated spirits or wax and grease remover, cut the sheet to the required shape with scissors or a knife, peel the self-adhesive backing, and press into position. No specialist tools or separate adhesive are required.
Is 12 square feet enough to cover a full bonnet?
12 square feet covers the full bonnet area of most standard passenger vehicles. For larger vehicles or applications where full coverage is required, contact us and we can advise on whether additional material is needed for your specific bonnet dimensions.
