Cold intake air can really add horsepower! Bring some into your throttles! Made in-house at TWM, this air box will serve several purposes:

• Provides a plenum for cold air drawn through a remote filter system. Very important for efficient functioning of electronic fuel injection systems.
• Helps to reduce intake "roar".
• Helps equalize distribution to individual intake runners.

To fit the 4-cylinder air box, on 2900 series throttle bodies, it will be necessary to install extensions (shown left), This unit is made of fiberglass and has a 3" inlet tube. There is a carbon fiber box also available
