The K&N AirCharger 63-1101 air intake system replaces the restrictive factory air filter and air intake housing in some Ford Focus models. K&N intakes are designed to dramatically reduce intake restriction as they smooth and straighten air flow. This allows your Focus’s engine to inhale a larger amount of air than the factory air filter assembly. More air means more usable power and acceleration throughout the engine’s RPM range. The 63-1101 air intake comes with a K&N XStream Top air filter designed for higher air flow and durability. It directs air through an aerodynamically engineered intake tube into the engine’s throttle body for a guaranteed power gain. The XStream Top air filter can be used for up to 100,000 miles before servicing is needed depending on driving conditions. This air intake is relatively easy to install using commonly available tools. This air intake cannot be sold in California. It is not legal for use in California or other states adopting California emission standards.

Customer Feedback

Intake Kit

I have a 2004 Ford Focus with a 2.3L.  I installed a K&N Aircharger part # 63-1101 in about 30 minutes.  What a difference.  The throttle response and drive-ability increase was unbelievable.  Its clear you spent a lot of time developing this part.  Thank you it was definitely worth the money.

Very Good Intake. Installed on my 2009 Ford Focus 2.0L SES. As soon as I started driving it, there was a great difference in power and sound. After about a week of driving, I noticed my gas mileage rose. The only problem we had was installing it, which took about 3 hours, but it was all worth it.

I have K&N filters in all of my cars and I love them. They hold up for years and they are easy to clean. This last one I bought for my Ford Focus was a bit difficult to install as it fit really tight. I like my K&N hat too.
