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.
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.
