Upgrade your charge pipes with the do88 charge pipe kit! This comprehensive kit includes all pipes and hoses to and from the intercooler, designed to complement and further improve the performance of high-output engines, including those using the do88 Performance Intercooler rated for up to 1000hp.

The OEM charge pipes are often not optimal from an airflow standpoint, featuring several narrow, tight, and flow-reducing bends. The do88 system outperforms the OEM kit with significantly better airflow and added reliability, making it sufficient for all further tuning regardless of your output goals.

Significant Airflow Improvement

The do88 pipe kit is significantly bigger with smooth transitions, offering a 31% increase in airflow. It delivers 638 CFM @ 150mbar (2.17psi) compared to the OEM flow of 440 CFM. This reduction in backpressure allows your engine to breathe freely and perform at its peak.

Superior Design and Construction

  • Hot Side: Features a large 70mm (2 ¾") aluminum pipe from the turbo to the intercooler. This mandrel-bent pipe eliminates the restrictive, flat design found on the OEM pipe. It is finished in a discrete, matte black powder coat for a sleek appearance and long-lasting protection.
  • Cold Side: A robust cast aluminum charge pipe runs all the way from the intercooler outlet to the throttle body. This eliminates two potential leak points found in the factory setup.
  • Larger Connections: The cold side pipe features a huge 86mm hose connection to the intercooler (compared to the OE 64mm), matching the inner diameter of the do88 Performance Intercooler for a smooth transition.

Advanced Features & Reliability

This kit is engineered for performance and durability:

  • Accessory Ports: The cold side pipe includes two CNC-machined 1/8 NPT connections, perfect for methanol injection or boost pressure sensors.
  • Reinforced Hoses: All included hoses are reinforced with 4 layers to cope with high boost pressures and temperatures. They feature a stepped inside at the pipe connections to reduce turbulence.
  • Secure Assembly: The kit is rounded off with high-quality hose clamps for a secure, leak-free assembly.
  • BOV Compatibility: Compatible with 2019+ cars using the included adapter for BOV recirculation.

Product Versions

We offer this kit in two versions to ensure perfect fitment for your specific setup:

  1. OEM Intercooler Version: Includes hoses adapted for the standard OE size intercooler connections (70mm).
  2. do88 Intercooler Version: Includes hoses adapted to match the do88 Performance Intercooler (ICM-420) with larger hose connections (80mm).

Please ensure you select the correct version for your vehicle's intercooler setup.
