Last time we dyno tested our assembled prototype for sound and performance. Maximum gains were achieved in the midrange of the rpm band to the tune of 10 whp and 13 wtq. These are impressive numbers. We saw gains from the start of the pull through redline, averaging around 5–7 whp/wtq throughout.

The sound produced by the VQ with our intake installed is nothing short of awesome! The large air filter and reduced restriction produces a deeper, amplified induction tone that sounds quite satisfying from behind the wheel.

Our last task is to fully model our design in Solidworks and construct our final prototype for fitment confirmation. As we mentioned last time, minor tweaks were needed to perfect fitment.

Intake 3D Models

With our prototype airbox in hand and our adjustment notes ready, we began constructing our 3D models of the final design. Check out the renderings!

Final Prototype Fabrication

Construction of the final prototype will be based on the dimensions of the final model, which will allow us to verify that our fitment is 100% spot on.

First, we split up the model into separate pieces so that we could map out the cuts needed for the airbox. These were then printed out as templates for the individual pieces.

We then adhered these templates to a sheet of steel to start fabrication.

We went to work with the band saw, grinder, bender, shears, and sander to accurately construct the individual pieces of our airbox.

All components are ready for welding.

We then began putting this puzzle together with the help of our TIG-welder!

Once the box was fully welded, we used the sander to clean up the welds and smooth the joints.

Final Prototype

Once the seams were smoothed and represented the desired quality of our final product, the prototype was complete.

This piece was painted, and we attached weather-stripping on all edges to ensure vibrational noises are eliminated during operation. Check out a few fully installed shots!

Coming Up!

Development and product design are complete for our first Nissan 350Z air intake system. From the power gains, to the fitment, to the sound produced, we are extremely pleased with how this setup turned out.

Now that our first batch of intake kits is being manufactured, we are preparing to launch a discounted pre-sale for those interested in picking up this kit. Check back soon for details on pricing and shipping information!

Thanks for following our development progress!

    1. Thanks Roy! I will certainly shoot you a link as soon as the pre-sale launches. We are hoping to set this up for early next week.

      Thanks!

    1. Hello Miguel,

      Thanks for the interest! We are intending to launch our pre-sale next week! Keep an eye on the “Coming Soon” section of our site for the intake. In addition, we will announce the launch of our pre-sale on My350z.com.

      Thanks

    1. Hello,

      Thanks for the interest! We have not yet test fit this particular intake on a G35. Because of this, we cannot 100% confirm or deny fitment. If we do bring a vehicle in for test fitting, I will certainly let you know the result.

    1. Miguel,

      Correct. We experienced a couple of delays with components in the kit. We expect our batch of pre-sale units to ship out by the end of next week.

      Sorry for the inconvenience!

      -John
