Your Audi A4 is an ideal balance between performance and effectiveness, sportsmanship and intelligence. This is a great car for your daily tasks, but an even better car for driving it on a highway. That means you have to take good care of your vehicle and find the right performance upgrades and accessories to keep it in the best condition it can possibly be in. Fortunately, CARiD stocks a range of such upgrades, and one of them is an aftermarket Audi A4 air intake.

The benefits you can expect from this component include increased horsepower and torque, increased fuel mileage, more aggressive engine sound, and smoother throttle response. You get these benefits because an aftermarket air intake allows your engine to get a large volume of cold air. Moreover, most of aftermarket air intakes are topped with an advanced air filter engineered with better filtration technology, so your engine is protected almost entirely from any hazardous debris. Available in different sizes and styles, an aftermarket air intake is easy to install compared to other upgrades. We are sure that you'll find this performance part to be one of the most cost effective for your A4!

      Can an Air Intake System also Increase My Fuel Economy?
      We all know that achieving better fuel economy while driving puts money back in your pocket and does the environment a favor. But for those who are actively interested in squeezing the most out of every drop of gas, getting more miles per gallon can actually become a sport - especially if a vehicle has a manual transmission that can be upshifted earlier and put into neutral during downhill grades or when coasting to a stop sign.

      The Real Cost of Your Car’s Cheap Factory Air Filter
      In today's world, saving money wherever possible has become essential. But it's important not to lose sight of the fact that, sometimes, a product that costs more up front will save you more money over time. In our business, we've seen far too many consumers judge products solely on the basis of their initial cost, completely neglecting any long-term economy and benefits. When it comes to automobiles, "performance" air filters are a perfect example of this.

      My Car is Brand New | Why Should I Change My Air Intake System?
      Aftermarket air intake systems have become one of the most popular engine modifications available for late model cars and trucks. An easy question to ask is why are these so popular? After all, didn't engineers who work for your vehicle manufacturer spend years developing the best engine components available? Since power and fuel economy are major selling points these days, it's hard to imagine car companies not doing everything they can to maximize horsepower, miles per gallon, or both.

      What are the Different Types of Air Intake Systems?
      There are many types of aftermarket air intake systems that range from simple and inexpensive to elaborate. In the scope of this article, we'll examine the different types of air intakes, what they do, and look at a few specific product examples of each. But in short, performance air intake setups increase airflow into your engine - boosting combustion and creating more horsepower and torque that you can actually feel. Their relatively low cost and easy installation (bolt-on in most cases) keeps them in popular demand by car enthusiasts that own everything from 1.5-liter turbo motors to big block V8 engines.

      Why Does My Car Have a Plastic Intake Manifold?
      An intake manifold is an integrated assembly that sits atop the engine, consisting of a series of tubes which distribute fresh outside air to each and every cylinder. On V-shaped engine blocks, an intake manifold typically sits between the two cylinder banks while inline engines may feature a manifold to the side of the cylinder head. Intake manifolds serve as a mounting point for carburetors, throttle body assemblies, fuel injectors, thermostats, and more depending on vehicle manufacturer engineering preferences. Intake manifolds may also serve to route coolant through dedicated channels in order to remove heat from the engine. Because of their location and functionality, intake manifold assemblies are under constant stress from engine vacuum pressure as well as direct heat from coolant, cylinder combustion gasses, and the cylinder heads to which they are mounted.

    2007 Audi A4 Base
    Not sure if I even notice a difference at all other than sound, but I changed my exhaust as well so the sound could be coming from there. Easy to install, looks cool.
