Stock L5P charge pipes choke airflow with undersized diameters — this kit replaces them with a 3.0-inch hot pipe and 3.5-inch cold pipe in 304 stainless, freeing up restriction without changing factory mounting points. The 5-ply silicone couplers and stainless clamps handle boost reliably, and throttle response improves with the reduced backpressure.

Features

• 304 Stainless Steel Mandrel-bent tubing
• Heat-resistant and weather-resistant silicone couplers
• Improved throttle response, increased airflow
• Billet-aluminum connectors with Viton O-Ring
• Constant tension spring clamps

Manufacturer Description

Boost your L5P with the PPE high-performance intercooler charge pipe kit. Replace the restrictive 2.5 Inch hot pipe and 3.0 Inch cold pipe with PPE's free flowing 3.0 Inch hot pipe and 3.5 Inch cold pipe. Constructed from premium 304 stainless steel, this kit provides superior durability and environment resistance.

Engineered to eliminate factory restrictions, these pipes improve throttle response and enhance airflow. The high-pressure hot side pipe is designed to be a single, seamless unit, reducing pressure drop and ensuring uninterrupted airflow.

This kit conveniently includes two billet aluminum quick-connects, one for the intercooler and one for the throttle body. Each connector comes with a Viton seal and a steel retainer clip. PPE Performance Silicone Couplers and constant tension spring clamps are also included.
