Spark plugs
 

Still got the original factory spark plugs in my car & as they still start the car first time without fail, I've not bothered to change them til now. So today I took one out to see which they were, but found no name just NLP 100290 printed on them, so what make are they?? as I'd like to order some new ones.

That's the MGR part number, I'm not sure who the supplier was.

Looked at Rimmers but they're way OTT at £8 odd each + postage.

I agree, ebay has NGK plugs for much more reasonable prices.

6 plugs at £8 each works out over 10 years at £0.0131506849315068 per day.

Will my car last that much longer, or more to the point, MEeeeeeee

if you don't want to pay for platinum plugs, just chuck in some 99p ngk plugs and change them every 10k or 20k instead!

I've started supplying Bosch plugs - these have excellent feedback from customers who've fitted them into KV6-engined 75s and ZTs:
