12261-21060 PCV Ventilation Hose for Toyota Corolla Yaris Vios Sienta 1NZ-FE 1.5L Engine

1. Product Details

Product Overview: This crankcase ventilation (PCV) hose, OE number 12261-21060 (also 1226121060), keeps your engine running at peak efficiency by channeling harmful blow-by gases from the crankcase back into the intake system. It is manufactured as a direct OE-equivalent replacement, matching the original part in dimensions, shape and connection layout for a plug-and-play fit. By maintaining correct crankcase ventilation, it prevents oil sludge build-up, stabilizes idle and helps the engine stay within proper emission levels.

OEM Equivalence: Built to original equipment specification with the same mounting points and internal diameter as the factory hose, this 12261-21060 breather pipe is the practical replacement choice for workshops, distributors and end users.

Why Replace: A cracked or hardened PCV hose can cause rough idling, higher oil consumption, a whistling vacuum leak and even the check engine light. Replacing the original hose with this 12261-21060 ventilation pipe restores correct crankcase pressure and keeps the whole emission system working as designed.
