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).
