Increase engine performance with theSTILLEN air intake for Nissan 370Z Z34. The GEN 2 features the most optimal horsepower and torque gains. ThisSTILLEN Nissan 370Z air intakehas a polished finish. ThisZ34 370Z intakeprovides a better air flow to the engine with the smooth surface tubing construction.

For those With a Dual Throttle Body 6th gen 370Z owners who want improved performance with a show quality shine, we've introduced our Gen 2 Long Tube Intakes. We replaced the restrictive factory air boxes with two (2) oil filters. These filters are designed with an integral velocity stack and attach to our newly designed polished aluminum long tubes. Replacing the factory intake tubes with the STILLEN design adds additional horsepower, and a great look for the engine bay.

The Z34 filters sit inside custom-fitted urethane intake boxes, which ensure no hot engine compartment air gets sucked into the intake tract. This creates a cold air path, and unlike other manufacturers who only partially shield the filter from hot underhood air, STILLEN has fully enclosed the filters and draws on cold air from behind the grille, for optimum performance.

As with all of our urethane intake boxes, these can be left natural black or painted to match the color scheme of the car.

The STILLEN Generation 2 Long Tube Dual Hi-Flow Intake for 6th gen 370Z is mild under cruising situations, and really comes to life creating an impressive intake note under acceleration.

***Does not fit fit 2018+ model vehicles. For those vehicles we highly recommend our extremely popular Gen. 3 intakes.
