For many reasons the Z was forced into hiatus during the late 1990’s. When it resurfaced in late 2002 it wasn’t alone. Nissan Motors, who also builds luxury vehicles branded as Infiniti, created a line of Infiniti cars based on the Z platform. The now legendary G coupe and sedan were born out of this relationship.

The 2009 to 2016 Nissan 370z and 2008 through 2013 Infiniti G37 are well-engineered machines. However, K&N engineers are constantly in pursuit of more power. After looking under the hood, K&N engineers knew that with their expertise these cars were capable of more. Much consideration was put into the design of part number 69-7078TS for the 2009-2016 Nissan 370Z and 2008-2013 Infiniti G37 models with a 3.7L V6 engine.

The stock intake tract uses a dual intake set up fed by dual air boxes and air filters. K&N intake 69-7078TS replaces the stock pieces with twin powder coated mandrel-bent aluminum intake tubes and dual K&N High-Flow Air Filters™ for improved air delivery. 69-7078TS incorporates two unique heat shields isolating the dual air filters from the warm air under the hood. This intake system provides improved performance and attractive silver powder coated aluminum Intake tubes to match the color of the engine bay.

The result of this hard work and enthusiasm for performance is estimated at over 14 horsepower at the wheels. K&N’s Research and Development Department tested a 2009 Nissan 370Z with a 3.7L V6 engine on our in-house dynamometer. Results showed horsepower increases throughout the RPM range with a shocking peak horsepower gain of an estimated 14.2 horsepower @ 5,600 RPM! Equally impressive is the estimated 13.34 lb-ft of torque this car picked up at 5,600 RPM.

This air intake system uses two conical shaped, High-Flow Air Filters. RU-4960XD captures harmful particles, flows more air, and provides long service life. This K&N air filter performs for up to 100,000 miles before service is required, depending on driving conditions.

In addition, K&N offers a RX-4990DK Drycharger® filter wrap that can be used in conjunction with part number 69-7078TS. Drycharger® filter wraps are durable pre-filters that are designed to filter large dirt particles and thus extend the time before the main air filter needs to be cleaned. These wraps can also repel water but add little restriction to the airflow of your filter. The wraps specifically designed for this intake filter are available in black, blue, red, and yellow.

69-7078TS is a complete system which takes about 90 minutes or less to install with common hand tools. It uses stock mounting points, requires no drilling, and is covered by the K&N Million Mile Limited Warranty®.
