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 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.
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:
