GPD 1811935 Ignition Knock Detonation Sensor Direct-Fit Replacement

The GPD 1811935 is a direct-fit replacement ignition knock (detonation) sensor engineered to meet or exceed original equipment fit, form, and function. Knock sensors play a critical role in engine management—mounted on the engine block, cylinder head, or intake manifold, the sensor detects abnormal vibrations caused by engine pre-ignition or detonation and signals the ECU to adjust ignition timing, protecting the engine from damage.

Key Features:

• Direct-fit OE replacement — no modifications required
• Engineered to meet or exceed OE specifications for fit, form, and function
• 100% tested for durability and performance prior to leaving the factory
• Responds to knock frequencies up to 1000 Hz, accommodating shifts in engine knock frequency across a broad range of operating conditions
• Manufactured with an automated data acquisition system to continuously monitor sensor output and verify correct voltage response at the specified frequency range
• New unit — not remanufactured

Warranty: GPD products are warranted to be free from defects in materials and workmanship for a period of one year from the date of purchase.

The GPD 1811935 is a professional-quality ignition knock sensor designed for reliable, long-lasting performance as a replacement for a failed or faulty OE unit.
