We control the process from jig to weld — no outsourced mystery parts. Each manifold and hard line is built on dedicated fixtures to ensure repeatable fitment, alignment, and gasket sealing.

Smart Packaging & Serviceability:

• 2-piece charge pipe for easier install and removal

• CNC’d adapters and block-offs that fit correctly the first time

• Routing focused on clearing factory components and keeping access for future service

Thermal Control That Makes Sense:

• Carbon fiber turbo blanket included standard

• Proper oil drain and feed geometry to avoid oil pooling issues

• Coolant tank relocation hose kit to clean up routing and keep temps under control

Complete Hardware & Plumbing:
You’re not left guessing line sizes or running to the hardware store mid-install. Feed, drain, vacuum, gaskets, block-offs — it’s in the box.

This kit is built for the enthusiast who wants OEM-level fitment with race-ready potential.
