We are proud to announce the release of our 69 mm cold air intake system for the Nissan 370Z and Infiniti G37 platform!

These intakes are fabricated and tig welded in house using 6061 aluminum tubing and were designed to achieve maximum performance. The 69 mm diameter was chosen due to the fact that the OEM throttle body opening is very similar in size thus creating maximum airflow and the least amount of pressure differential going into the engine.

Prior to releasing this intake kit we will perform testing on a Nissan 370Z with full bolt ons and then an Infiniti G37.

1. 2009 Nissan 370z (manual)

Modifications: Tim Bell Long Tube Headers, True Dual Exhaust, SOHO Ported Upper & Lower Intake Manifold, Stillen Gen 3 Intakes, DW 600CC Injectors.

*SOHO Intake Kit was installed and then re-tuned via Ecutek on the same day*

Results:

You can see that power was very similar between the two intake systems until 5600 rpm where power started to increase with the SOHO intakes. We saw an increase of up 7+ rear wheel horsepower on this vehicle.

2. 2008 Infiniti G37 (automatic)

Modifications: Berk HFCs

*SOHO Intake Kit was installed and then tuned via Uprev on the same day*

Results:

Once the intakes were installed onto the vehicle a tune was required as the air fuel ratios were not optimal for horsepower due to the increase in airflow and the stock ecu not being able to compensate. Uprev was installed along with the ARC patch and we saw gains of up top 25 rear wheel horsepower and 18 ft-lbs of torque on a humid day.

Advantages:

- MAF housings have been relocated to the underside of the piping providing a sleek look

- Increased horsepower & torque throughout powerband

- Improve Engine Bay Appearance

Intake Kit Includes:

- (2) K&N Filters w/ Clamps

- (2) Silicone Straight Hoses

- (2) Silicone Hose (45 Degree)

- (1) SOHO Crankcase Breather Hose Kit

- (8) T-Bolt Clamps

- Instruction Manual

*A TUNE IS REQUIRED TO ACHIEVE MAXIMUM PERFORMANCE*
