Good To Know

Q: Will this adapter plate cause air restriction? A: No, the adapter is engineered with a smooth taper to maximize airflow and transition the bore size efficiently between the manifold and throttle body. It prevents air turbulence in the intake stream.

Q: Do I need to use RTV silicone with this adapter? A: It is recommended to use the provided gasket or O-ring for a clean, leak-free seal without relying on messy silicone sealants.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
