Description
Unlock peak performance from your VW/Audi 1.8T 20V engine with the IE Intake Manifold—finished in a sleek, durable black powder-coat. This true motorsport-grade manifold is designed from the ground up to outflow the factory intake, delivering dramatic horsepower and torque gains across the full RPM range.
Ideal for big-turbo applications, this intake manifold features aggressively sized resonance-tuned runners, CFD-optimized bellmouth velocity stacks, and a large plenum chamber for exceptional mid-to-top-end performance with minimal loss in turbo response. Whether you're running a GT28 or a bigger setup, this manifold is your gateway to serious street or track power.

Performance Engineering
Every detail of this manifold has been obsessively developed for maximum airflow efficiency. Using advanced Computational Fluid Dynamics (CFD), Integrated Engineering engineers optimized the runner length, plenum volume, and bellmouth shapes to reduce restriction and boost volumetric efficiency. The result is faster airflow, more combustion, and more power.
