The 2015 BMW 335i xDrive is a fantastic machine, blending performance with luxury. But, like any car enthusiast, you might be looking for ways to squeeze even more power and responsiveness out of your ride. One of the most common and effective upgrades is an aftermarket air intake. Let's dive into why you might consider upgrading your air intake, what to look for, and some potential options for your 335i xDrive.

Why Upgrade Your Air Intake?

So, why should you even bother upgrading your air intake on your 2015 BMW 335i xDrive? Here's the lowdown:

• Increased Horsepower and Torque: This is the big one! Aftermarket air intakes are designed to improve airflow to your engine. By reducing restriction, your engine can breathe easier, leading to a potential increase in horsepower and torque. While the gains might not be massive (think 5-15 horsepower in most cases), you'll likely feel a difference in throttle response, especially in the mid-range.
• Improved Throttle Response: A less restrictive air intake means your engine can react quicker to your throttle inputs. This translates to a more responsive and engaging driving experience. You'll notice it when accelerating from a stop or passing on the highway.
• Enhanced Engine Sound: Let's be honest, who doesn't love a good engine note? Many aftermarket air intakes are designed to amplify the sound of your engine, giving you a more aggressive and sporty tone. You'll likely hear more of the turbocharger spooling, which can be quite addictive. The 2015 BMW 335i xDrive already sounds great, but an upgraded intake can really enhance the auditory experience.
• Aesthetic Appeal: Some aftermarket air intakes look fantastic under the hood. If you're someone who likes to show off your engine bay, a new air intake can add a touch of style and visual appeal. Many come with sleek designs and high-quality materials like carbon fiber.
• Improved Fuel Efficiency (Potentially): While not always guaranteed, some users report a slight improvement in fuel efficiency after installing an aftermarket air intake. This is because the engine doesn't have to work as hard to draw in air. However, this is often a marginal gain and shouldn't be the primary reason for upgrading. For the 2015 BMW 335i xDrive, fuel efficiency might improve slightly, but driving habits have the biggest impact.

What to Look for in an Air Intake for Your 335i xDrive

Okay, you're sold on the idea of upgrading your air intake. But with so many options available, how do you choose the right one for your 2015 BMW 335i xDrive? Here are some key factors to consider:

• Compatibility: This is the most crucial factor. Make sure the air intake you choose is specifically designed for your 2015 BMW 335i xDrive. Check the product description and compatibility charts carefully. A universal intake might not fit properly or perform optimally.
• Filter Type: Air intakes typically come with either an oiled cotton filter or a dry filter. Oiled filters generally offer better filtration and performance, but they require periodic cleaning and re-oiling. Dry filters are easier to maintain, but they might not filter as effectively. Consider your driving environment and maintenance preferences when choosing a filter type. For the 2015 BMW 335i xDrive, both oiled and dry filters can work well, but consider the maintenance aspect.
• Intake Material: Air intakes are typically made from aluminum, plastic, or carbon fiber. Aluminum is durable and offers good heat dissipation. Plastic is lightweight and more affordable. Carbon fiber is the most expensive option, offering a combination of lightweight and heat resistance. The material can affect the intake's performance and aesthetics. The 2015 BMW 335i xDrive can benefit from any of these materials, but carbon fiber adds a premium touch.
• Design: The design of the air intake plays a crucial role in its performance. Look for intakes with smooth, mandrel-bent tubing to minimize airflow restriction. Also, consider whether the intake is a short ram intake (SRI) or a cold air intake (CAI). SRIs draw air from inside the engine bay, while CAIs draw air from outside the engine bay, potentially providing cooler air. For the 2015 BMW 335i xDrive, a CAI might offer slightly better performance, but installation can be more involved.
• Brand Reputation: Stick with reputable brands that have a proven track record of producing high-quality air intakes. Read reviews and do your research before making a purchase. Established brands often offer better support and warranty coverage. For the 2015 BMW 335i xDrive, consider brands known for BMW performance parts.
• Price: Air intakes can range in price from a couple of hundred dollars to over a thousand. Set a budget and stick to it. Remember that you don't necessarily have to spend a fortune to get a good quality air intake. The 2015 BMW 335i xDrive doesn't require the most expensive intake to see benefits.

Installation and Maintenance

Once you've chosen an air intake, you'll need to install it. Some air intakes are relatively easy to install, while others may require more technical expertise. If you're not comfortable working on your car, it's best to have a professional install the intake for you. Installation costs can vary depending on the complexity of the job.

• Installation: Many air intake kits are designed for relatively straightforward installation, often involving simple hand tools. However, always consult the manufacturer's instructions. Some kits might require removing more components than others. If you're not confident, a professional installation is always recommended, especially for the 2015 BMW 335i xDrive, to avoid any issues with the car's sensitive electronics.
• Maintenance: Maintaining your air intake is crucial to ensure optimal performance and longevity. Oiled filters need to be cleaned and re-oiled periodically, typically every 20,000 to 30,000 miles. Dry filters can be cleaned with compressed air or a vacuum cleaner. Always follow the manufacturer's recommendations for cleaning and maintenance. Regular maintenance will keep your 2015 BMW 335i xDrive running smoothly.

Conclusion
