3.9i auto spark plugs

SatcomLandy · Aug 25, 2014

I would like to change my disco's spark plugs which plugs do you find the best? I don't have lpg just petrol.
I see some old post's but none are new so I will ask again.
I'm getting old and cannot remember what plugs I fitted to my ex army V8 110, I can remember that I fitted a blue dizzy cap & blue magnecor leads.
Thanks
Gerald

Factory fit Champion RN11YCC then u could have NGK BPR6ES.
Bosch and Denso also do plugs for the V8

NGK BPR6ES also work well if running Lpg in this engine as NGK plugs tend to have a faily broad temperature range and at around £16.00 for 8 great value for money!

I have been running NGK BPR6Es in my petrol 3.9i for three years with no issues. Often doesn't get used for more than a week and still starts first time whatever the weather.

NGK BPR6ES £1.86 each at euro car parts at the moment.
