Audi A4 AFE Cold Air Intake System is a must have when it comes to performance parts.  The stock intake system on your car is good but the AFE Cold Air Intake is great.  It will add horse power and torque instantly to your car.  AFE Cold Air Intake also lets you choose performance and filter options.  AFE Cold Air Intake systems are engineered and designed to fit your car using the factory mounts and holes that are already there.  That means super easy "Bolt On" installation with simple tools and no drilling or other modification necessary.  Most kits come with powder coated steel heat shield for optimum cool air and the AFE performance filter of your choice.      

AFE will replace the factory intake system that is choking your car and open up the air ways to ensure that your engine is running the best way possible.  Some of the AFE cold air intake kits will replace the entire factory set up which means the utmost efficiency possible.  Some have seen massive gains up to 50 horse power.  AFE Cold Air Intakes work together with all of your other engine customizations and mods to bring out the most in your car.  

You will receive everything that is needed in the AFE Cold Air Intake Kit to optimize performance and give you excellent performance that will fit great on your German engineered car.  AFE Cold Air Intake Systems are covered by a Lifetime Warranty too.
