If you're looking to give your 2004-2008 Nissan Maxima V6 3.5L a little extra oomph, the HPS Performance 827 Series Air Intake Kit (Part # 827-558WB) is worth checking out. This isn’t just another intake; it’s designed to really open up your engine's potential. The 3-inch mandrel-bent aluminum tube lets air flow in like it’s on a mission, boosting horsepower and torque while keeping your throttle response sharp. And don’t worry about messing with your air-fuel ratio—this kit keeps everything safe and sound.

The heat shield is a nice touch too; it keeps the hot air away from your air filter, which means cooler, denser air getting into the engine. That’s key for performance. Installation? Piece of cake. The kit comes with a manual that has clear pictures and step-by-step instructions, so even if you're not a pro, you can get it done without needing any special tools or modifications. Plus, it won’t throw a CEL (check engine light) your way, which is a huge relief.

One thing I really like about this kit is the durability. The aluminum alloy tubing is lightweight yet tough, and the reinforced silicone hoses are built to handle the heat, even when you're pushing your car hard. The industrial-grade stainless steel T-bolt clamps keep everything tight and secure. You won't be worrying about parts loosening up on a spirited drive.

And let’s not forget about the air filter. It’s designed to maximize airflow while still keeping out the junk, and it’s washable and reusable. So, you can keep it clean without having to shell out for replacements all the time. All of this is made right here in the USA, which is a nice bonus.

• Boosts horsepower and torque without needing a tune after installation.
• Lightweight 3-inch aluminum piping replaces the stock air box, optimizing airflow and heat dissipation.
• Comes with race-proven reinforced silicone hoses and industrial-grade stainless steel T-bolt clamps for reliability.
• Heat shield keeps the air filter cool for better performance.
