The Injen SP1989 cold air intake system for your 2009-2017 Nissan 370Z 3.7 V6 is the perfect upgrade to your vehicle. After removing your factory airbox, the Injen intake tube is directed directly behind the front bumper to acquire colder, direct air. Injen uses a proprietary design using multiple pieces that are dyno tuned to make the path. The larger and cleanable Injen air filter then goes on the end of the intake tube to complete the system. You wont ever have a check engine light because your mass air flow sensor bolts right up to the Injen intake on the 2009-2017 Nissan 370Z 3.7 V6. Injen dyno tuned this intake to ensure maximum horsepower and torque gains on your 2009-2017 Nissan 370Z 3.7 V6 while still maintaining proper air/fuel ratios. Depending on your driving habits, many users have also reported noticeable gains in fuel mileage, making the intake pay for itself over time!We GUARANTEE the LOWEST price on all Injen Products!
What Makes Injen Intakes better than their competition?Not only are all Injen Technology Intakes made in the USA, Injen cool air intake systems feature MR Technology, developed by Injen to maintain safe air/fuel ratio and highly efficient tuning. Injen also does extensive dyno tuning and r&d before releasing an intake, unlike many other companies who take an "if it fits, use it" attitude to aftermarket intakes.

We get this question all the time… Which Injen Air Filter should I pick??
Here at New Level Motor Sports we like to provide you with options. That’s why we are one of the only Injen retailers who gives YOU the choice as to which Injen filter you want: The Injen Oiled Filter (K&N Style) or the Injen/AMSOIL Dry Filter.
Injen Intake Systems are available with two different kinds of filters: Dry and Oiled. The Injen Oiled filter is a K&N Style filter. It is a pleated filter that features 5 layers of filtration. It allows for significantly more air flow than OE air filters. The filtration rate on oiled filters is over 98%. Oiled filters need to be cleaned periodically (every 10-20k miles, depending on the conditions you drive in) and will need to be reoiled after the cleaning. You can purchase a cleaning kit from an auto parts store, or we sell the cleaning kit here on our website.
The Injen/AMSOIL Dry is an oiless filter that can be cleaned with a shop vac, which makes cleaning much easier than the oiled filter. The filtration on the dry filters is over 99%, so they are slightly more efficient in terms of filtration.
There is no difference in horsepower or torque between the wet and dry filters. The main difference is your personal preference. Some people love the oiled filters and others love the dry filters. Either one is going to work fine and they are 100% interchangeable (if you have a dry filter and later want to replace it with an oiled filter or vice versa you can do so).
We recommend the dry filter over the oiled filter due to its ease of cleaning and slightly better filtration. Also, with a dry filter you don't risk fouling your mass air flow sensor by over oiling an oiled filter during cleaning.
