Frequently Asked Questions
Will this hose need clamps, and what size should I use?
Yes, you'll need hose clamps to secure both ends. Since this is a 4-inch diameter hose, use T-bolt or worm-drive clamps rated for that size. The exact clamp size depends on the ID of your barbed fitting or adapter.
Can I use this on a turbo intake or only for coolant?
This hose is rated for boost, coolant, and vacuum applications. If you're running it on a turbo intake, confirm your boost level stays within the hose's pressure rating—silicone typically handles 15–20 psi reliably, but check the specs for your specific turbo setup.
Do I need to do anything to prep the hose before installation?
Inspect the interior and exterior for defects before cutting or fitting. If you're trimming the length, use a sharp utility knife or hose cutter to avoid fraying the edges. Soak the hose ends briefly in warm water if they're tight over fittings—silicone softens slightly when warmed.
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.

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.
