Frequently Asked Questions
Will this work for both coolant and boost applications?
Yes. The 3-ply reinforcement handles positive pressure (turbo/supercharger intake) and negative pressure (coolant overflow return lines) equally well. Just confirm your system's max psi rating before install.
Do I need clamps, and what size?
You'll need hose clamps at both ends — typically 2" clamps on the inlet side and 3" on the outlet side. Check your system's existing clamp size to match; some builders prefer worm-drive clamps for repeated adjustments.
Can I use this straight out of the box or does it need prep?
Straight out of the box is fine. Rinse the inside with clean water before connecting to coolant systems to remove any mold release residue, especially if it's been stored a while.

Can I install OEM parts myself, or is it better to have a professional handle it?
While some OEM parts can be installed by DIY enthusiasts, the complexity of installation can vary. For the best results and to ensure proper fitment and performance, we recommend having a trained mechanic install the parts, especially if you’re unfamiliar with automotive repairs.
