The design requirements for this intake are similar to our others: the intake should reduce as much restriction as possible, it should be easy to tune and accurately measure incoming airflow, it should properly filter out potentially harmful particles, and it should look like something you’re proud to have in your engine bay.

We designed this intake to meet these goals by using only minimal bend angle and pipe length which helps to decrease restriction.  Additionally, our low restriction washable air filter helps here too, while still filtering particles down to 5 microns.  We have also incorporated an air straightener into our design, an invaluable feature that was not utilized on the OEM airbox until later models.  Finally, we have continued our “Stealthbox” heatshield design, utilizing it to not only keep hot air away from the air filter, but to cover up unsightly components such as the ABS pump.

Less obvious features of this intake include the location of the air filter.  Specifically that we made sure that the filter is not close enough to the ground such that water/hydrolocking is a concern. The heatshield also contains provisions to mount the factory clips that hold the two coolant hoses that would traditionally mount to the OEM airbox. This keeps them out of the way, and maintains a clean aesthetic.  The design of the heatshield also acts to hide the power steering pump reservoir, but does not hinder inspection or filling.  Overall what is accomplished is a true hybrid of traditional Cold Air Intakes and Short Ram Intakes, with all the advantages and none of the compromises.

Materials

In true GrimmSpeed fashion, no corners were cut in the fabrication of each and every one of these intakes. The aluminum heat shield is laser cut, CNC bent and riveted together before receiving a heavy duty black texture powdercoat. MAF flanges are CNC machined from 6061 aluminum and the intake tube is fabricated from 5052 aluminum and CNC bent.  The air straightener is laser cut from 6061 aluminum as well, and tumbled before the entire assembly is TIG welded by our expert welders. After welding, each tube receives our heavy duty wrinkle powdercoat and is inspected and cleaned to ensure maximum performance and reliability. 

Performance and Tuning

At GrimmSpeed we love tuners, and we like to make sure they love us back. Our intakes are notoriously easy to tune, and this one is no different.  The consistency of the airflow through the MAF sensor makes this intake very predictable and is as easy to tune as the stock airbox. While pro-tuning is always recommended, the Cobb OTS AccessPort Maps can sometimes provide a safe temporary alternative based on your vehicle and level of modification.
