The outermost provides a direct fit to the LT5 (ZR1) supercharger. BENEFITS: • Essential component in high-performance engine modification, with exceptional high flow capacity• Lower weight to power ratio at part throttle, for a more nimble/spirited driving experience • Linearization and smoothing of the curve for a more predictable response and crisper shifts• Immediate response right off idling while keeping idling function undisturbed (No Hesitation/Stumble)• Does not require tuning to run, but tuning is highly recommended for optimal performance• No drivability, idle, tuning, or similar issues relating to similar-sized throttle bodies.• More air/power at every single throttle position after idle. • Easy Installation
