GPD 1811843 Ignition Knock Detonation Sensor Direct-Fit Replacement

The GPD 1811843 is a direct-fit ignition knock (detonation) sensor replacement from Global Parts Distributors (GPD), a trusted name in OE-quality automotive components. The knock sensor monitors the engine block, cylinder head, or intake manifold for abnormal vibrations caused by pre-ignition or detonation, feeding real-time data to the ECU so it can adjust ignition timing and protect engine integrity.

Key Features:

• Engineered to meet or exceed original equipment (OE) fit, form, and function
• 100% tested for durability and reliable performance prior to packaging
• Direct-fit replacement for a straightforward, hassle-free installation
• Manufactured from premium materials for long service life
• Backed by GPD's 1-year limited warranty against defects in material and workmanship

A failing knock sensor can trigger a check engine light, reduce fuel efficiency, and allow engine-damaging detonation to go uncorrected. The GPD 1811843 restores proper ignition timing control, helping your engine run at peak efficiency. Note: This part has been restricted from sale in the state of California.
