The AEM 21-821DS fits some Nissan 370Z models. See vehicle applications for details.

The 21-821DS Performance Cold Air Intake System produces horsepower and torque gains by replacing the restrictive air filter and air intake housing. This air intake system was designed, tuned and dyno-tested to fit specific Nissan 370Z models. This system replaces both the left and right side intakes. The AEM Dryflow synthetic washable air filter does not require oiling and can be used up to 100,000 miles before servicing is needed (depending on driving conditions). The heatshield is a two piece design and also utilizes the factory air ducting. The intake tube is constructed from mandrel bent aluminum and has a durable gray powder coat finish. This air intake system was developed to accommodate the mass air flow sensor and PCV hose. The air intake system is backed by AEM's Lifetime Limited Warranty. Some AEM air intakes are not legal for sale or use in California and other states adopting California emission standards, while others are 50 state legal.

Product Disclaimers

Aftermarket Body Kits (Authentic & Replica)

Aftermarket body kits, whether authentic or replica will always require extra work to dial-in the fitment to the end-users liking. We highly recommend utilizing a custom professional body shop with aftermarket body kit experience in fiberglass or carbon fiber. Each brand will have different tolerances for fitment. Some will fit better than others. The body kit's material will also come into play (e.g. fiberglass, polyuretehane, carbon fiber, etc). The purchaser/end-user is fully responsible for finding the appropiate body shop and all fees associated with installation, fitment, modifcation, preparation and paint associated with the product.

Installation and Paint of Body Kits

A professional and custom body shop experienced in aftermarket fiberglass and carbon fiber body kits is required for proper installation and painting of these products. Aftermarket body kits do not fit like OEM products and generally require extra work for optimal fitment. Fitment will be dependent on the quality of the body shop choosen. A dry test fit is required before any modifications and painting is done. Outcast Garage nor the respective manufacturer will not be able to warranty a defective product if it has been modified or painted without a proper dry test fit nor be responsible for any credit towards labor or paint if the product is defective. An inexperienced or incorrect body shop may result in high labor rates, ill-fitting parts, and peeling paint.

Fiberglass (FRP)

There will always be minor sanding, shaving, cutting, tweaking, adjusting, drilling and/or filling will be required prior to installing these parts. All primer finish included with the parts but be sanded as well as other preparation work required before painting. All fitting and paint preparation is the responsibility of your body shop. The product's respective manufacturer nor Outcast Garage will be responsible for the quality of a body shop's work if it does not meet the customer's expectations. Body kits must be test fitted on the vehicle prior to painting to check for any manufacturer's defect. Any part that is modified is non-returnable and no refund wil be given.

Carbon Fiber Care (CF, CFRP)

All carbon fiber products will require an automotive-grade clear coat for protection against the sun's UV rays unless the clear coat is included with the product from its respective manufacturer. Products infused with a 'UV Protection Resin Gel' should still be covered with an automotive-grade clear coat. Body kits must be test fitted on the vehicle prior to painting to check for any manufacturer's defect. The product's respective manufacturer nor Outcast Garage will be not not warranty or be responsible for discoloration of the carbon fiber nor be responsible for the quality of the clear coat applied by the body shop if it does not meet the customer's expectations.

Hand-Laid Carbon Fiber (CF, CFRP)

The 'Carbon Fiber Care' disclaimer also applies to hand-land carbon fiber products. Depending on the complexity and design of the product, there may be a slight and minor shift in the carbon fiber weaves. It is almost impossible to achieve 'perfection' with hand-land carbon fiber. These 'slight and minor shifts' in the carbon fiber weaves does not equate to the product being defective. If the weaves are extreme, and do not fall within an acceptable tolerance, then it will be eligible for a warranty replacement if the product has not been altered in anyway. A warranty claim must be filed first before any further action can be taken. Body kits must be test fitted on the vehicle prior to painting to check for any manufacturer's defect. Outcast Garage will not be responsible for a refused shipment of a carbon fiber product if it does not meet expectations without first initiating a warranty claim and receiving approval. Inspections and refusing of shipments are only for damaged products during transit (cracks, chips, bends, holes, scratches, etc).

Polyurethane Care, Installation & Painting (Poly)

All polyurethane parts will come raw and unpainted. These parts are flexible so they may slightly warp during shipment. Slightly warped polyurethane parts are not considered defective. They will require a few hours of sunlight to return to its original shape from when it came out of the mold. Polyurethane parts are much different than factory OEM parts and require specific preparation before painting. Improper paint preparation will result in the paint not adhering to the bumper, pin holes and bubbles. It is normal for polyurethane parts to come slightly scratched with imperfections. Proper sanding during paint preparation will remove all imperfections. Please seek a professional and reputable body shop with experience with polyurethane aftermarket parts. Body kits must be test fitted on the vehicle prior to painting to check for any manufacturer's defect. The product's respective manufacturer nor Outcast Garage will not be responsible for the body shop's preparation, fitting and paint job if it does not meet the customer's expectations.
