Fitment: Calais VE, Caprice WM, Commodore VE, Statesman WM

For further details, please refer to the vehicle fitment guide in the above image.

These parts are manufactured from a thermo-composite plastic which prevents the manifold from heat-soaking, maintains a cooler charge air temperature and generates a higher resistance to knock. The result is sustained horsepower gains and crisp-like throttle response.By using this combination, the volumetric efficiency of the motor can be improved by a noticeable margin over the entire rev range.

Contents:

• 1 X 6.35mm Plenum spacer
• 1 X Bolt pack
• 1 X Silicone gasket maker
• 2 X 25mm Manifold insulator
• 4 X Spacer bush

Part Number: MI639

Notes:

• Due to the substantial increase in height, this combination will require minor modification to ensure proper fitment under the bonnet. The plastic cowling will need to be trimmed and a section of the bonnet lining will have to be cut out. A re-stocking fee will apply if under bonnet clearance is misjudged and a kit needs to be returned/exchanged.
• Please take any necessary measurements prior to purchase. We will not be held responsible for any clearance issues you may have as every vehicle is made with slight differences.
• Please contact us for any installation or fitting queries.
• If space allows, a combination of a 12mm plenum spacer with a 6.35mm manifold insulator for forced induction and a 12mm plenum spacer with a 25mm manifold insulator for a naturally aspirated setup, is ideal. These can be purchased through other listings.
• These components can be purchased separately through other listings.
