Why Choose AFI?
- AFI specialises in electronic fuel-injection, ignition and engine-management components.
- KN1093 is catalogued specifically for the applicable early 370Z application.
- Sold individually, allowing customers to order one sensor or the vehicle’s full quantity of two as required.
Replacing Both Sensors?
The applicable 370Z uses two knock sensors. If both sensors have been confirmed for replacement, select a quantity of 2 before adding the product to your cart.
Please Check Before Ordering
KN1093 is catalogued for 2009–2013 370Z models and should not be assumed to fit later vehicles. Confirm the vehicle’s build date, engine and removed sensor before ordering.
A knock-sensor fault code does not confirm sensor failure by itself, as wiring, connector or sub-harness faults and genuine engine detonation can produce similar symptoms.
