Powered by Nissan's award-winning 3.5-liter V-6, the 350Z's powerplant produces 287 horsepower at the crankshaft. With the Typhoon® system installed, testing on K&N's Dynojet 248 dynamometer showed a 10-12 average horsepower increase at the 350Z's rear wheels.
Unique intake tracting, unlike any existing K&N Typhoon® kit, makes the impressive power gains possible. Cool air is drawn into the system through a roto-molded plastic intake scoop that mounts behind the 350Z's front fascia. Incoming air travels through this scoop into a 2.5" OD, 6061 aluminum delivery tube en route to a 5-way airbox. K&N's 350Z Typhoon kit includes a carbon-fiber lid, created in K&N's advanced-composites shop, for the ultimate high tech performance look.
Inside the airbox is K&N's famous FilterCharger®. The filtration surface is constructed of four layers of pleated, oil-impregnated cotton sandwiched between epoxy-coated aluminum wire mesh. As with all K&N air filters, this FilterCharger® can be cleaned and re-oiled with a K&N Recharger Kit (sold separately).
Filtered air then travels to the engine through a mandrel-bent, 3" aluminum induction tube. This one-piece, straight-through tube has a billet aluminum adapter for the engine's mass-airflow sensor. The adapter is located in the optimal position to maximize airflow and is TIG-welded to the intake tube. This Typhoon® kit's tubes are available in four finishes: polished aluminum and dual-stage powdercoated red, blue and silver. Typhoon® applications are available for the 350Z Coupe and 2004 Z-Roadster. The 350Z Typhoon® Intake System is covered under CARB EO# D-269-27.
