Bougie is een onderdeel van het ontstekingssysteem voor benzinemotoren.

In de cilinderkop geschroefd en verbonden met de hoogspanningskabel, levert deze de hoogspanningsvonk over de elektrodeafstand om het samengeperste lucht/brandstofmengsel in de verbrandingskamer te ontsteken. Een correct warmtebereik en elektrodeafstand zijn afgestemd op de motorspecificaties om een betrouwbare start, soepele loop en volledige verbranding te garanderen.

Frequently asked questions

Which engines does the RTC3812 spark plug fit?

The RTC3812 spark plug fits the Defender 2.5L 4-cylinder petrol, the Discovery 1 V8 EFI petrol, and the Range Rover Classic V8 EFI petrol. It's the Champion N9YC equivalent, threaded into the cylinder head and connected to the HT lead to ignite the air/fuel mixture.

How many RTC3812 spark plugs do I need?

You need one spark plug per cylinder, so a Defender 2.5 4-cylinder petrol takes four, and a V8 EFI Discovery 1 or Range Rover Classic takes eight. Plugs are always replaced as a complete set so every cylinder fires evenly.

What does the RTC3812 cross-reference to?

The RTC3812 cross-references to Champion RN9YC and N9YC, plus PSB7E2, BP6 and BR2330. These are equivalent plugs for the same petrol applications, so any of these codes points to the correct fitment for these engines.

What are the signs the spark plugs need replacing?

Common signs include misfiring, hard starting, rough idle and poor fuel economy. Worn or fouled plugs struggle to spark cleanly across the electrode gap. Set the gap to your engine's workshop specification when fitting new plugs.

Does the RTC3812 fit all Discovery 1 models?

On the Discovery 1 V8 EFI the RTC3812 covers VIN FA393361 to WA799999. Confirm your build falls in that range, and note the Range Rover Classic V8 EFI application runs up to VIN HA610293.
