Frequently Asked Questions

Will this fit my radiator outlet or intercooler piping?

The 3.50" inner diameter suits most turbo intercooler setups and larger radiator hoses. Measure your existing hose ID before ordering to confirm fitment.

Do I need clamps or any hardware to install this?

You'll need hose clamps sized for 3.50" diameter to secure both ends. Spring clamps or worm-gear style work; the hose itself comes bare.

Can I splice this into an existing coolant line?

Yes — 12" is long enough to bridge a section or serve as a repair patch. Use two clamps per connection point for reliable seal under pressure.
