CP-E's cast intake manifold is engineered from the ground up to maximize plenum volume, overall performance, and reliability.
A casting was chosen to keep everything as smooth as possible without breaking the bank. It allows us to use F1 style bellmouths for the inlet to each intake port. This was a very complex casting to produce, but we are very excited to bring something to market with all these features. Every manifold includes all the hardware to allow the customer to run either a stock style throttle body or the larger 74mm throttle body from Chrysler.
In addition to providing a greater plenum volume, the cp-e intake manifold adds provisions for port fuel injection with the HavocRail™. Adding this rail in addition to the manifold allows your Mazdaspeed to make massive power without fuel cuts or the risk of running lean. In the real world, the cp-e Intake Manifold translates to more even airflow distribution, increased top end power, and the possibility of additional fuel supply.
When you’re pushing your Mazdaspeed to the limit, there is no better choice than cp-e.
- Fully cast design allows for maximized flow
- CAD & CFD optimized runner design
- Designed for top end power
- Optional port fuel injection with HavocRail™
- Stock style or larger 74mm Chrysler Throttle Body
Mazdaspeed Intake Manifold Highlights
F1 Style Velocity Stacks
The manifold features smooth race car inspired velocity stacks on our intake manifold. Each bell mouth was carefully designed and CFD tested for ideal flow.
After countless hours of testing and re-design, cp-e is very happy with the smooth airflow provided by their intake manifold. With no abrupt changes and smooth contours everywhere, their intake manifold promotes consistent, even flow that is needed to maximize air entering the combustion chamber.
Larger Throttle Body
The Havoc™ Intake Manifold can accommodate the stock throttle body, but it also has provisions to use a larger 74mm Chrysler throttle body for better performance.
cp-e designed the Havoc™ Mazdaspeed Intake Manifold to improve the volumetric efficiency of the fuel air intake in every way possible. A big part of this equation was allowing for a larger throttle body to be used. This in conjunction with their velocity stacks allows for some impressive airflow.
Easily Add Port Fuel
Every intake manifold ships with pilot holes pre-drilled for an easy port fuel addition. When it’s time to add port fuel injection, the customer can drill these holes out at home with a simple hand drill. These holes along with cp-e's HavocRail™ allow for port fuel injection for maximum gains.
With the addition of port fuel, your Mazdaspeed can get incredibly efficient fueling using the stock direct injection alongside this secondary fueling system. This duel fuel setup allows for you to run 4 additional port fuel injectors alongside your overworked stock DI injectors.
Cylinder Head Connection
Bored out your cylinder head? We have you covered. The cylinder head connection on our Havoc™ Mazdaspeed Intake Manifold is sized to support higher flowing heads. This removes a massive restriction in the factory intake manifold and allows for high power builds.
