FAQ
Is the CSF 7221 a direct fit?
Yes. It drops into the factory location with no cutting or modification.
Do I need it on a stock FL5?
It is most useful for track days, hot climates or tuned cars where coolant temperature climbs under sustained load.
How long does shipping take?
Delivery times vary by part because many items ship directly from the manufacturer or distributor. Message us before ordering and we'll confirm current lead time.
Can I return it?
Yes. Returns are accepted within 30 days of delivery. The customer pays return shipping, and a restocking fee of up to 20% may apply.
