Product Resources
Features & Product Details
When it comes to cold air intake systems, GrimmSpeed is a trusted company that invests the proper research and development to produce an effective intake system that provides real-world results. The same concept is no exception for the latest Stealthbox Cold Air Intake System.
Here are some additional specs:
• +32WTQ (14.3%) and +21WHP (9.6%). This is achieved through an off the shelf tuning device.
• Designed in CAD: Perfect mating with the factory turbo and ram-air scoop.
• Low bend angle aluminum tube: Minimize restriction and maximize performance.
• Shielded MAF sensor placement: Protects MAF from heat, which will increase the accuracy of the readings.
Also incorporated in this intake is the careful placement of the MAF on the intake. The provision of the MAF has been placed within the intake pipe so that the MAF can provide the vehicle with readings that are as close to OEM as possible.
Included in this intake system are the following:
• 1X CNC bent intake tube with MAF flange
• 1X GrimmSpeed high-flow air filter
• 1X Aluminum heat shield
• 1X 12” MAF harness extension
• 1X Silicone hump coupler
• 3X Stainless steel worm clamps
• 2X MAF Sensor machine screws.
In conclusion the Stealthbox Cold Air Intake System has professional fit and finish quality. The intake pipe, as well as the heat shield are powder-coated a bright red finish for a clean look, and for anti-corrosion resistance. The filter is serviceable, which makes this intake a great modification that will give you a lifetime of performance.
