Chevy TPI/LT1 Air Foil

The Chevy TPI/LT1 Air Foil by HOLLEY is a precision-engineered intake manifold component designed to optimize air flow and fuel distribution in classic Chevrolet TPI (Tuned Port Injection) and modern LT1 engine platforms. This compact aftermarket part serves serious engine builders and restoration enthusiasts who demand maximum efficiency from fuel-injected small-block and LS-based powerplants.

Constructed with HOLLEY's reputation for quality manufacturing, this air foil features precision dimensions (3.5 x 2.6 x 3.7 inches) and a verified weight of 0.15 lbs that integrates seamlessly into OEM and aftermarket intake configurations without adding parasitic mass. The foil design works by directing incoming charge air and managing boundary layer separation within the manifold plenum, reducing turbulence and promoting laminar flow into each intake port.

This air foil is particularly beneficial for TPI and LT1 engine owners seeking to enhance performance, especially in applications that require improved cylinder-to-cylinder air distribution and more consistent fuel atomization. Whether fine-tuning a stock restoration or extracting peak performance from a modified engine, this component addresses critical variables in intake manifold design.
