| One of the quickest and best ways to improve the performance of your 2001-04 C5/Z06 Corvette is to eliminate the restrictive stock air box. This easy-to-install FlowPac includes an air filter--dubbed the "Blackwing™" for its unique appearance--out-flowing the factory setup by as much as 90% and can provide up to 18 additional horsepower.
Add in a new smooth bellows designed to replace the restrictive accordion-style factory bellows, straightening out air flow between the inlet duct and throttle body for an added increase in horsepower worth up to 23 horsepower over stock. Each bellow is constructed of high-quality, fiberglass-reinforced silicone and offers a single-rib design for flexibility.
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 hardware and complete detailed instructions are included.
NOTES: Does not fit 1997-00 Corvettes order Part #21114E for proper fitment. Part #25017 filter cleaning kit is required when cleaning/re-oiling your filter.
SLP Blackwing is designed to fit the stock MAF Sensor and Air-Bridge, we do not guarantee fitment with aftermarket MAF sensors and air-bridges. |
