Can A Fan Spacer Make A Difference In Your Build?

We were surprised to learn recently that the folks at Flex-a-lite can actually tell if a customer uses a fan spacer from another manufacturer?

Even though most car builders consider a fan spacer a commodity product–as long as you find one the correct length the brand doesn’t matter–it turns out that Flex-a-lite have added several design features into their spacers to improve the performance and durability of the fan. In fact, Flex-a-lite won’t warranty their excellent radiator fans if they discover it was used with a spacer made by another manufacturer.

So why is that and how can they tell if one of their fans have been used with another manufacturer’s spacer? This video explains it all, and it makes perfect sense. Check it out.
