Ported LGX Intake Manifold

The Tracy Lewis LGX Ported Intake Manifold is engineered to unlock hidden power by dramatically improving airflow efficiency throughout the intake tract. Each manifold is carefully ported to reduce restriction and smooth airflow, allowing the LGX engine to breathe easier and pull harder across the entire RPM range.

When combined with our ported throttle body, Tracy Lewis quotes horsepower gains in the 20 HP range, along with crisper throttle response and stronger mid-range performance. Upgrade to our 80mm throttle body, and Tracy Lewis quotes 25 to 30 horsepower, delivering a noticeable increase in top-end power and overall engine responsiveness.

The result is an LGX that feels sharper, more aggressive, and more eager to rev. Whether you're chasing better track times or simply want a more engaging driving experience, this ported intake manifold delivers real, proven performance gains without sacrificing everyday drivability.
