The AEM 21-548R Performance Cold Air Intake System produces horsepower and torque gains by replacing your vehicle’s restrictive factory air filter and air intake housing. This air intake system was designed, tuned and dyno-tested to fit specific Infinity G35 models. Air enters the system through an oversized AEM Dryflow synthetic washable air filter for outstanding air flow, filtration and performance. The air filter is relocated to the driver-side wheel well which is designed to reduce intake air temperature and increase horsepower. The intake tubing is constructed from mandrel-bent aluminum featuring a durable red powder coated finish. This air intake system was developed to accommodate the engine’s factory emissions control devices including the mass air flow sensor and crankcase vent tube. The tapered cylinder shaped AEM Dryflow air filter is made from an oil-free, synthetic filter media that can be used for up to 100,000 miles before cleaning is needed (depending on driving conditions). 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.

This is the second intake system I've ordered from AEMintakes.com in the past 10 months. Very easy online ordering process, if I do have to call and ask questions, everyone is always so helpful, curteous and knowledgeable. Great company, awesome product.

Power gains aren't very noticeable but it's definitely a necessity if you plan on building a fast car. Sounds great, someone who doesn't know any better would say it sounds like a turbo. Only thing I would like to see change; for the price you pay, it should come with a cleaning kit for the filter. I'd buy it again.
