Product Description

This Stage 2 intake kit replaces the L5P's restrictive plastic factory intake system top to bottom - intake pipe, air box, and all - with a fabricated aluminum setup finished in gloss black. The intake horn steps up 1.1" over the factory diameter, meaningfully increasing airflow to the turbo for improved horsepower, torque, and throttle response, while pulling in cooler air through the hood's Ram Air duct and inner fender.

It's a genuine bolt-on installation with no tuning required, using basic hand tools and high-quality silicone boots and stainless T-bolt clamps for a clean, reliable fit. Just remember to disable the factory air filter monitor system after installation to avoid a recurring service message, since the dry filter isn't tracked by the stock sensor logic.
