DESCRIPTION

The GrimmSpeed StealthBox Cold Air Intake System is the result of countless invested hours in research and development to provide the performance enthusiast with a proper intake system designed to add power and performance to your vehicle. This intake system is a direct replacement for the highly restrictive factory intake system that leaves plenty of room for improvement. GrimSpeed has provided you with a comprehensive solution that allows your turbocharger to inhale large volumes of air with a clear flow path free of restrictions straight into the turbocharger.

MAF diameter and placement, total bend angle, filter location, and heat shield design were the primary variables during the design phase. To ensure accurate readings, unaffected by the intense heat of the engine bay, MAF sensor placement absolutely must be within the heat shield. To minimize restriction, it was important to keep the total bend angle in the intake tube as low as possible, but still raise the filter location away from the ground to protect it from the elements. Lastly, testing showed the importance of utilizing the factory ram air scoop to feed the otherwise stagnant air in front of the fender.

The GrimmSpeed intake produced an additional 32ftlb (14.3%) at 3000rpm and 21whp (9.6%) at 5500rpm, with healthy gains all the way across both curves.

WHY?

The GrimmSpeed Black Stealthbox Intake is the best way to grab some power gains without breaking the bank. Easy to install and manufactured to handle power and heat, this intake allows for better flow to your turbo resulting in increased power and function for your vehicle.
