Help keep ignition timing dialed in and guard against damaging engine knock with the NTK Ignition Knock (Detonation) Sensor ID0308. It installs as a direct-fit replacement for the 2006-2011 Honda Civic (L4-2.0L) and 2006-2009 Honda S2000 (L4-2.2L).
This sensor monitors the vibrations caused by engine knock or detonation so the engine control system can adjust ignition timing. A piezoelectric crystal generates a varying voltage based on vibration intensity, signaling the computer to delay timing and help prevent severe, costly engine damage. If a failed knock sensor is the cause, symptoms that may point to replacement include a check engine light, engine hesitation, poor fuel economy, or a failed emissions test — diagnose the cause before replacing.
- Piezoelectric operation: converts engine vibration intensity into a varying voltage to help manage ignition timing.
- Connector: single male blade terminal in a square female connector.
- NTK build: reinforced components help reduce failure and resist corrosion and moisture; shielded harness helps block electrical interference.
- Fit & support: manufactured to meet or exceed OE fit, form, and function, with mounting threads and wire gauge matched to OE; backed by a 3-year/36,000-mile warranty. Mounting hardware is not included.
Made in Mexico.

Frequently Asked Questions
What does this knock sensor do?
It monitors vibrations caused by engine knock or detonation. A piezoelectric crystal produces a varying voltage based on vibration intensity, letting the engine computer adjust ignition timing to help prevent detonation and engine damage.
Which vehicles does the NTK ID0308 fit?
It's a direct-fit replacement for the 2006-2011 Honda Civic (L4-2.0L) and the 2006-2009 Honda S2000 (L4-2.2L). Check the Buyer's Guide tab to confirm fitment for your vehicle.
What are signs this sensor may need replacing?
Possible signs include a check engine light, engine hesitation, poor fuel economy, or a failed emissions test. These can have other causes, so diagnose the fault before replacing the sensor.
Is mounting hardware included?
No, mounting hardware is not included. The sensor's mounting threads, harness length, and wire gauge are matched to OE for installation.
What warranty and country of origin apply?
The sensor is backed by a 3-year/36,000-mile warranty and is made in Mexico.
