URO NI1317947 Ignition Knock Sensor for Nissan

The URO NI1317947 is a direct-replacement ignition knock sensor designed to restore proper engine performance and fuel efficiency on compatible Nissan and Mercury vehicles. This critical engine management component monitors cylinder pressure to detect abnormal combustion (knocking or detonation) and signals the engine control module to adjust ignition timing accordingly, preventing potential engine damage while optimizing power output.

Key Features:

• Direct-fit OE replacement design for easy installation
• Manufactured using high-quality polymer and corrosion-resistant metal materials engineered to withstand extreme engine heat
• Alloy conductors minimize electrical resistance for accurate operation and reliable signal transmission
• Plug-and-play wiring connection eliminates splicing or modifications
• Cost-effective alternative to OEM parts without sacrificing quality or performance

Replacing a failed knock sensor eliminates common symptoms including reduced fuel economy, loss of power, rough idle, and check engine light codes (P0325-P0334 range).
