Why Choose Bosch Double Iridium Spark Plugs?
- Fine-wire electrode construction provides a concentrated spark for dependable ignition.

- Direct replacement dimensions allow installation without adapters or modifications.
Please Check Before Ordering
Confirm the engine type before ordering. The VR7NII33X suits the VQ35HR and VQ37VHR engines but does not replace the spark plugs used in VQ35DE-powered 350Z models.
The advertised price is for one spark plug. Select a quantity of six when replacing the complete set.
Check the electrode gap before installation and tighten the plugs to the vehicle manufacturer’s specification. Do not apply excessive force to the fine-wire electrodes when checking the gap.
If you are unsure about fitment, contact Zend It Auto Parts with your model, year and engine before ordering.
