One of the quickest and best ways to improve the performance of your C5 Corvette is to eliminate the restrictive stock air box. This easy-to-install air filter--dubbed the "Blackwing" for its unique appearance--out-flows the factory setup by as much as 90% and can provide up to 18 additional horsepower. If you are looking for the quickest way to increase your C5 Corvette's horsepower, than you've found it. It's the best on the market.
The Blackwing uses 100% synthetic filtration media called Synteq. The fibers are extremely uniform and very small, allowing the filter to flow more air and trap smaller particles than do ordinary cotton and oiled-cotton "performance" filters. The Blackwing also features an exclusive flow indicator that changes color when cleaning is required.
This is a simple bolt-on installation that requires no vehicle modifications. All necessary parts and complete instructions are included. An add-on bellows kit (Part #21111) is required for all 2001 - 2004 models (including Z06s).
