Reliable Flap Movement, with OEM-compatible spring geometry
Spring is supplied to match OEM reference numbers including 95B133246B and 8R0133246 variants, so geometry and tension align with original specifications. The spring works alongside the electronic valve flap servomotor to provide return force and controlled motion.
Consistent actuation reduces stuck or erratic flap behaviour, helping maintain intended exhaust flow and engine response. Suitable for reinstating correct flap operation after wear or failure.
Durability and Longevity, with metal construction
Made from metal material designed to withstand repeated cycles and resist deformation under heat and mechanical stress. Construction focuses on tensile strength to preserve spring tension over time.
Durable build translates to fewer repeat repairs and more stable flap operation in everyday driving. Workshops will find fewer callbacks for premature spring failure.
Straightforward Fitment, with direct replacement design
Manufactured for direct installation, matching mounting points and form factor of the original spring so no modification is required. Installation process replaces the worn spring and secures into the existing actuator assembly.
Quick swap reduces labour time and complexity, making it practical for DIY enthusiasts and professional mechanics. Installation returns the actuator assembly to secure, seamless operation.
