Genuine TB37H3 Breather Hose For 97-02 Ford F150 Expedition F250 4.6L V8

If you've got a 1997 to 2002 Ford F150, Expedition, or F250 with the 4.6L V8 (VIN code W), and you need a breather hose, this is the one.

It's a brand new, genuine part, number TB37H3.

No aftermarket guesswork here—this is the real deal.

It's the factory-style hose that routes crankcase gases back into the intake.

If yours is cracked or clogged, it can cause rough idling or oil leaks.

Swapping it out is easy and cheap insurance.

This fits a bunch of years: 1997, 1998, 1999, 2000, 2001, and 2002.

Just double-check your VIN and engine size before ordering.

It comes with a 12-month warranty, so you're covered.

Simple part, crucial job.
