N52 N51 Silicone Intake Boot (Intake Resonator Delete)

Silicone Intake Boot — N52 (Silencer Delete)

A direct replacement for the factory rubber intake boot that ditches the built-in silencer, so the engine breathes and sounds the way it should. The stock rubber piece cracks and hardens with age and muffles intake note by design — this silicone version fixes both, opening up a more aggressive induction sound while restoring a clean, sealed connection to the airbox.

Features

• More engine character — deletes the restrictive factory silencer for a fuller intake note under throttle
• Silicone construction — far more durable and longer-lasting than the OEM rubber it replaces; a straight swap for worn or cracked stock boots
• Plug and play — bolts up to the stock airbox with no modification required
