JMF Intake Manifold V2 Port Injection Mazdaspeed 3 2007-2013 | Mazdaspeed 6 2006-2007
- In stock, ready to ship
- Inventory on the way
With over a year of research and development JMF is proud to introduce the first sheetmetal intake manifold with port injection on the market for the Mazda Speed cars. This manifold was designed to not only look awesome but to perform even better.
Each manifold is hand made and TIG welded from high quality 6061 T6 aluminum. The lower half is completely CNC machined from billet aluminum. Radiused inlets are CNC machined into each plenum bottom to improve airflow by 10-15%.
Extensive testing was done on various setups and improvements were made in every aspect. You can see for yourself in the collection of test result graphs in the pictures section. Even on a stock turbo car with no additional tuning and simple bolt ons the intake manifold produced an additional 8hp/11ft-lbs and drivability was improved greatly. Adding this manifold to a more serious setup yielded gains of 45hp with no additional tuning. With a proper tune and setup 60hp gains can be expected!
Every effort was made to keep this manifold as close to a stock replacement as possible. Installation for the most part is bolt on but some modifications to your IC piping will be required. This manifold will NOT work with the stock top mount intercooler, you will need to have a front mount intercooler installed. For more install tips scroll down. Professional installation is highly recommended!
Included with each manifold is all new stainless steel hardware, brass vacuum fittings, fittings to relocate your fuel pressure sensor, and vacuum hose. Also included is an extruded aluminum -6AN fuel rail along with CNC machined mounts and stainless steel hardware. The fuel rail ends are tapped for a 9/16"-18 thread for a -6AN O-ring adapter fitting. Fuel injectors are NOT included, we recommend the Bosch EV14 standard height injector. O-ring to O-ring height of the injector should be around 48mm. The fuel rail mounts are slotted to allow for adjustment of different sized injectors.
