Bring Your 2009-2017 370Z Up to NISMO Horsepower with an AEM Cold Air Intake
Bring Your 2009-2017 370Z Up to NISMO Horsepower with an AEM Cold Air Intake
Sep 22, 2017
Make up the power difference between the 2009-2017 Nissan 370Z with the 3.7L engine and the NISMO
When it was introduced for the 2009 model year, the Nissan 370Z was a complete departure from its predecessor, the 350Z. The new 370Z featured a four-inch shorter wheelbase with a reduction in overall length of 2.7 inches. The rear track was widened by 2.2 inches and there was a slight reduction in height. At the same time, the chassis was re-engineered to provide a 10-percent increase up front and 22-percent increase out back in torsional rigidity. With a fully independent front and rear suspension, it’s a sports coupe seeking a deserving engine.
And Nissan developed one - the engine in the 370Z was a new development as well. Known by its internal code, VQ37VHR, it is a V6 engine produced by Nissan with a displacement of 3.7L. It has an aluminum block with DOHC four-valve aluminum heads. The VQ37VHR was the first production engine to incorporate Nissan’s variable valve timing technology VVEL (Variable Valve Event and Lift). Compression ratio is 11.1:1 with a bore of 95.5 mm and a stroke of 86 mm, the short stroke evidence of its 7000 rpm redline. The VQ37VHR produces 332 horsepower in the base-level 370Z.
The AEM intake for 2009-2017 Nissan 370Z provides heat shields to protect the oversized filters
The 370Z NISMO package provides adds an incremental 15 horsepower for about $15K more on the sticker. AEM has a way to gain power and save yourself a good deal of money at the same time. The AEM 21-821DS cold air intake adds an estimated 15 horsepower to a standard 2009-2017 3.7L 370Z, as measured at the rear wheels on a chassis dynamometer. While exact numbers aren’t available, it’s likely that the increase exceeds the 18 horsepower difference measured at the flywheel, eliminating any drivetrain losses.
The AEM 21-821DS air intake system replaces the OEM plastic air boxes and flat panel air filters with powdercoated heat shields that better reject high underhood temperatures protecting two tapered conical air filters with significantly more surface area of the OEM filters.
The two red AEM 21-202DOSK Dryflow filters utilize a non-woven synthetic filter medium optimized for high air flow, improved performance, and excellent filtration characteristics. In fact, the Dryflow filter captures up to 99% of any harmful contaminants that could damage your engine.
From the filter, intake air passes through a pair of intake tubes fabricated from mandrel-bent aluminum tubes that have a durable gray powdercoat finish. In addition, the intake tubes accommodate the OEM mass air flow sensors and PCV hoses.
With the hood closed, the seals on the top of the air boxes provide a barrier against engine heat
The AEM 21-821DS cold air intake is a straightforward modification that takes just a few hours to install, guided by fully-illustrated instructions that are included in the packaging. Only a few tools are required for the installation. The AEM 21-821DS utilizes only the factory mounting locations, so there are no holes to drill or permanent modifications to make.
You can expect the two AEM 21-202DOSK air filters to provide reliable service for about 100,000 miles with proper maintenance (depending on driving conditions). Cleaning is quick and straightforward and consists of an application of AEM 1-1000 synthetic air filter cleaner the filters. The AEM cleaner loosens and dissolves dirt and grime collected on the filters. After an application of the cleaner, the filters need only be rinsed with water until clean, dried, and then reinstalled in the car.
The AEM 21-821DS is designed to fit the following vehicles:
