Each kit includes:

• 2 VTA billet aluminum inserts
• 2 4-ply silicone sleeves
• 2x intake recirculating caps
• 4x connecting clamps

The ModalWorks M177 VTA adapters are a simple bolt on solution to enhance the sound and engine bay appearance of your W205 C63 and X253 GLC63.  The VTA adapters redirect airflow away from your intake system to provide more audible pressure release. On a stock system, the recirculated air is pumped back into your intake system which makes the blow-off sound significantly muffled.  With this kit, you will hear increased blow-off noises as well as have a cosmetic upgrade that is front and center in your engine bay.
