Upgrade your 1990-1997 Mazda Miata (NA) with these OEM heater core pipes from a 1999-2005 NB.

They're used but in good working condition.

Note: trimming to the heater core box on NA models is required, but there are plenty of online write-ups on how to do the modification.

This is a popular upgrade for better fitment or replacing corroded originals.

Pipes only, no box.

If you're handy with a little DIY, these pipes are a solid solution.

Get that heater working right!
