The Nissan 370Z came to market with a very good dual intake system which has proved quite difficult for any company to improve power gains over the stock intake system. That being said, many companies have tried and many have already failed. One company that has not failed is Stillen. So what's the difference with the Stillen intake system? We take a look.
With the G3, sound is mild during normal driving but spirited under acceleration, intensifying over 5,500 RPM.

This intake has a radically new design that provides dramatically better power than any intake on the market for the VQ37 equipped vehicle’s. The Stillen R&D team engineered and dyno tested more than 50 variations before being satisfied that this system is the best that can be made for the VQ37 engines.
The new Gen 3 Ultra Long Tube Intake places two large K&N filters in front of the radiator. Strategic placement of the filters allow for optimum cold air flow. It features additional polished tubes that pass through the front core support, larger air filters than the Generation 2 unit. On some applications such as the G37 a urethane splash guard is included in the kit to help protect the filter. This is only necessary on vehicles with larger grill openings from the factory. All kits feature a system of varied diameter tubing and steps to maximize air velocity.
The power result: A dyno-proven 20 horsepower gain at the wheels on the Dual Throttle Body 350Z, 18.5 horsepower gain at the wheels on the G37 Coupe and 17.5 horsepower on the 370Z. This translates to an estimated 20-22 horsepower gain at the flywheel! For G37/G35 Sedan owners, gains are 14 horsepower at the wheels. No other intake for the VQ can match these power gains!
Recommended installation requires removal of the front fascia clip (not absolutely necessary for some vehicles, but significantly aids in ease of installation) and slightly enlarging the holes through the front core support. Installation time is estimated at two hours for an experienced technician. No other part relocation or parts removal is required.
Now after doing a little more reading and research, we found an article on www.motoiq.com. They did their own research and they got virtually the same power gains as Stillen did, however one thing sticks out like a sore thum. The 20 horsepower gain at the wheels only comes when the front bumper is removed! Now one of two things would have to happen here, you'd have to drive around with your 370Z bumper removed or by cutting holes in the bumper where the filters are located. Expect close to 9 horsepower or slightly more with your bumper in place and no holes cut in your bumper.
