Crawford Performance Intake Manifold Spacer (Billet Power Block - BPB)

[Adi 40]

New, genuine, bought from US, never installed.  £325

Significantly improves the drivability of the stock car.  Installs in an hour or less. Will not affect MOT, etc.

Best NA power mod if you do not want to go the manifold + tune  route, which is several times more expensive.

* Improves OEM Torque Dip by 300 RPM on a Totally Stock BRZ 
* Improves Acceleration
* Decreases Delay between Shifts with AT
* Increases the Volumetric Efficiency of your Intake Manifold

This is the real thing, not the cheap imitations you see from other sellers. It cost me around £400 including import duties and VAT.
