⚡ At a Glance
- • Ignition Performance: Consistent spark delivery for dependable cold starts and steady acceleration
- • Best for: Owners replacing worn plugs who want reliable starts and low-maintenance parts
- • Not ideal for: Drivers specifically seeking iridium or platinum electrode plugs
Factory-pre-set electrode gap removes the need for adjustment during fitting. Nickel-plated housing and robust ceramic construction improve wear resistance and corrosion protection.
Easy, accurate installation – thanks to factory-pre-set electrode gap
Electrode gap arrives preset at the factory so no manual adjustment is required; package lists the requested tightening torque or angle for fitment. Following the specified torque ensures correct seating and reliable ignition.
Simplified fitting reduces installation time and the risk of incorrect gaps affecting combustion. Suitable for routine garage work and DIY replacements.
Reliable cold starts – with design optimised for excellent cold start behaviour
Manufacturing and material choices are tuned to promote consistent spark formation in lower temperatures, a feature highlighted as excellent cold start behaviour. Ceramic insulator design contributes to stable ignition under varied conditions.
Fewer failed starts on chilly mornings and more predictable engine response when temperatures drop. Useful for drivers in colder climates or infrequently used vehicles.
Long service life and corrosion resistance – with nickel-plated housing and robust ceramic material
Nickel-plated housing and thread protect against corrosion and seizing, while a special ceramic material provides high dielectric strength and mechanical robustness. The combination increases wear resistance under combustion stresses.
Reduced likelihood of seized plugs at future servicing and extended intervals between replacements. Easier removal and lower long-term maintenance hassle for workshops and owners.

❓ Frequently Asked Questions
Q: How do I check if these plugs fit my car?
A: Use vehicle identification and the parts search tools provided, and observe any listed restrictions to confirm compatibility. Specified OE reference numbers do not form an exhaustive list.
Q: Do the plugs need the electrode gap adjusting before fitting?
A: No, the electrode gap is factory-pre-set so no adjustment is necessary before installation; follow the package torque or angle instructions when fitting.
Q: Should the thread be lubricated during installation?
A: Bosch advises not to lubricate the thread; the nickel-plated housing provides anti-seize protection and corrosion resistance.
