Frequently Asked Questions
Will this hose work for coolant circulation, or is it better for vacuum lines?
Silicone hose of this grade handles both coolant and vacuum applications. What matters is matching your system's operating temperature and pressure range to the hose spec — get that right and you're good either way.
Do I need hose clamps, and what size should I use?
You'll need clamps to secure the ends, but clamp size depends on your fitting diameter, not the hose itself. Measure your barbed fittings and go up one size for safety — most 4" ID setups use standard worm-gear clamps in the mid-range.
Can I cut this hose shorter, or does it come pre-formed?
Silicone hose cuts clean with a sharp blade or hose cutter — no special tools needed. Pre-form it to your routing, then trim if needed before final clamping.
K2 Industries & OUR OWN FAQ's
How do I check fitment?
Check the listing for your year, make, model, trim and engine. Body style, build date and factory options can matter. If the listing is unclear, send FI Performance your vehicle details and the product link or SKU before ordering.
What comes with this part?
Check the product description for quantities, hardware and accessories. Photos may show the part installed with other components. Ask us if you need to confirm whether a part is sold individually, as a pair or as a kit.
Will I need extra parts or modifications?
That depends on the part and your setup. Check for adapters, wiring, coding, tuning, trimming or additional hardware before booking installation. If you already have aftermarket parts, tell us what’s installed.
What should I check for headlights or tail lights?
Match your factory lighting type, connector and body style. Halogen, HID and LED assemblies can differ even on the same model. Check pre-facelift versus facelift fitment and features such as adaptive lights or leveling.
Should I have a shop install it?
We recommend a qualified installer for wiring, engine, brake and suspension work. Inspect the part and confirm fitment before cutting, drilling, painting or modifying anything.
When will my order ship?
Availability and lead time vary by item. If you’re working around a shop appointment or event, contact FI Performance for a current estimate before ordering.
How do returns and warranty claims work?
Contact FI Performance with your order number before sending anything back. Eligibility depends on the item, its condition and the applicable policy. If there’s damage or a defect, keep the packaging and send photos of the part, label and issue.
Is this part intended for street use?
Check the listing for any use restrictions and confirm the requirements where you drive. If you need a specific approval or certification, ask us to verify it for the exact part number before ordering.
