## Why this one

- **0.8 mm gap**: Set at the factory, Bosch type VR8SII33T.
- **23 Nm torque**: 26.5 mm reach, 14 mm plug socket.
- **Iridium both electrodes**: Slow electrode wear keeps the gap stable over long intervals.

## On the job

### What it does

Iridium on both the centre and the ground electrode wears very slowly, so the gap stays close to the factory 0.8 mm over long service intervals. That matters on hybrids, where the engine starts and stops constantly and every restart has to fire cleanly. Bosch type VR8SII33T, 26.5 mm reach, tightened to 23 Nm.

### Fitting and what else to check

Change all plugs on the engine in one go and fit them with a torque wrench into a cold head; aluminium threads strip easily. Blow out the plug wells before removal, and check the coil boots for tracking marks or cracks while they are off.
