Typically 1 required per vehicle

Original engine bay insulation mats commonly deteriorate over time due to heat, oil vapour, and age. As the foam breaks down, it can crumble into the engine bay, reduce sound insulation effectiveness, and create an untidy appearance. Replacing the mat restores proper acoustic insulation, improves engine bay presentation, and helps maintain cabin comfort.

When to replace
•   Original insulation foam is crumbling or deteriorating
•   Increased engine noise inside cabin
•   Visible sagging or separation of insulation material
•   During engine bay restoration or repainting
•   Heat damage or contamination from oil and debris
