Hi Ross,

This is a complete swap of the factory inlet manifold which is replaced by the dbilas ITB kit (Individual Throttle Body kit). The kit includes the following :

1.Throttle bodies (ITB's)
2.Intake manifold
3.Dbilas airbox
4.Throttle control linkage
5.All necessary parts to fit and run

The benefits of this are a much greater and more precise airflow through each individual body over the stock single throttle body and inlet manifold thus in short creating more power. ITB's generally give better top end power and can greatly improve throttle response. With ITB's more aggressive cams can also be installed without sacrificing a smoother idle which is also an added benefit and something that none ITB cars can suffer from when harsher cams are installed.

Oh did I mention they sound beautiful!!!

Dbilas rate the power increase at 20bhp on a stock engine once mapped/tuned accordingly.

Hope this helps,
