Buying guide — what actually matters for best cold air intake for infiniti q50
So, you've decided to upgrade your Infiniti Q50's intake system. That's awesome! But with so many options out there, how do you know which one is the right fit for you?
Let's break down what really matters.
Performance Gains: More Horsepower and Torque?
This is usually the main reason people opt for a cold air intake. The basic idea is to let your engine breathe easier by replacing the restrictive factory air intake with a less restrictive pathway. This allows more cooler, denser air into the engine, which can lead to a noticeable bump in horsepower and torque.
Look for kits that boast specific, measurable gains, and try to cross-reference those claims with user reviews. A kit that promises 5-15 horsepower is often realistic for naturally aspirated engines like the Q50's 3.7L V6, especially when paired with other modifications.
Airflow and Filtration Quality
A cold air intake isn't just about letting more air in; it's about letting cleaner, denser air in. High-quality intakes use performance air filters that are designed to be more efficient than stock paper filters. Look for filters made from materials like cotton gauze or synthetic media that offer a good balance between airflow and particle filtration.
A filter that doesn't capture enough dirt can lead to premature engine wear, and one that's too restrictive will negate any performance benefits. The actual piping material also plays a role; aluminum or durable ABS plastic is generally preferred over flimsy materials.
Sound Enhancement
One of the most immediate and noticeable changes you'll experience with a cold air intake is the sound. As the engine breathes more freely, you'll likely hear a more aggressive, sportier intake sound, especially when accelerating or under load. Some kits are designed to amplify this sound more than others.
Think about whether you want a subtle growl or a more pronounced roar. If engine sound is a big factor for you, check reviews specifically mentioning the intake note.
Installation Complexity and Fitment
Nobody wants to spend an entire weekend struggling with an installation. Most reputable cold air intake kits are designed as direct bolt-on replacements for the factory components. This means they should use existing mounting points and require minimal modification.
Always check the compatibility list carefully for your specific Q50 model year (e.g., 2014-2021) and engine size (3.7L V6). If you're not comfortable with basic car maintenance, factor in the cost of professional installation.
Material Quality and Durability
The intake system is exposed to engine heat and vibrations, so the materials used are paramount for longevity. High-quality intakes use robust materials like powder-coated aluminum or durable ABS plastics for the tubing. The air filter should be reusable and washable to save on long-term costs.
Look for kits that come with quality clamps and couplers to ensure a secure, leak-free fit. A well-built intake should last for many years and potentially outlive the vehicle itself.
Frequently Asked Questions (FAQ)
Will a cold air intake void my car's warranty?
In most cases, installing an aftermarket cold air intake should not automatically void your entire vehicle's warranty. However, manufacturers can deny warranty claims for specific engine components if they can prove that the aftermarket part directly caused the failure. It’s always a good idea to consult your owner's manual or speak with your dealership's service department about their policy on performance modifications.
We recommend keeping your original parts in case you need to revert for warranty work.
Can a cold air intake improve fuel economy?
While the primary goal of a cold air intake is to increase performance, some users report slight improvements in fuel economy. This is because a more efficient engine can sometimes use fuel more effectively. However, these gains are usually modest and often offset if you tend to drive more aggressively to enjoy the new sound and power.
Don't expect a huge jump in MPG; it's more of a potential side benefit.
What's the difference between a cold air intake and a short ram intake?
A cold air intake (CAI) is designed to draw cooler air from a location outside of the engine bay, usually from the fender well or lower front bumper area. This cooler, denser air can improve combustion efficiency and power. A short ram intake, on the other hand, typically relocates the air filter within the engine bay but still provides a less restrictive path than the stock airbox.
CAIs generally offer better performance due to the cooler air charge, though short ram intakes can be simpler to install.
Is the increased engine noise from a cold air intake too loud?
The sound enhancement from a cold air intake can vary significantly depending on the specific kit and your vehicle. For the Infiniti Q50's 3.7L V6, you can expect a more pronounced and sportier intake sound, particularly under acceleration. Many owners enjoy this more aggressive tone, but if you prefer a quiet cabin, it might be more than you’re looking for.
We recommend watching video reviews that showcase the specific intake noise to gauge if it aligns with your preferences.
How often do I need to clean or replace the air filter in a cold air intake?
The maintenance schedule for a performance air filter often depends on the type of filter and your driving conditions. Most reusable, washable filters (like cotton gauze ones) recommend cleaning every 15,000 to 30,000 miles, or sooner if you drive in dusty environments. Always follow the manufacturer's specific instructions for cleaning and re-oiling your filter to ensure it functions optimally and filters air effectively without becoming overly restrictive.
