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 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 black 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.

Received invoice from Clint Summerfelt. He’s great to work with and very knowledgeable. The intake sounds great (whistle when getting on the gas) and gives the car better throttle response. Install was straightforward and didn’t take long. Only negative I experienced is the filter is pretty close to the fender well. It doesn’t touch and probably has no negative effect whatsoever.
I wish I would have purchased this one first and never wasted my money on the Cobb Big SF. I had nothing but issues with the Cobb when it came to tuning, everyone was pointing me in this direction. Well, after installing it and having instantly no problems any more, I regret I didn’t buy this intake first. Such a clean install as well. Definitely worth the money.
I’m really happy with this purchase. I’m glad I went through with it because I was having doubts. I have no complaints or regrets on buying this mod whatsoever. Built in velocity stack, also comes with the heat shield which some of them don’t, or they do but additional price. Which probably equals the same price. But anyways the noise coming out from under the hood sounds amazing. With the boomba bvp, it sounds even sexier. Just waiting for my exhaust to come in and I’m set.
Sounds Awsome and nick was extremely helpful will definitely buy from here again!
Everything was super high quality opening it up. The install was an absolute breeze and the sounds this thing makes are unreal
