What spark plugs are alternatives to the Aston plug. I know they are NGK!
Also plug coils! Just got quote from Aston - plugs £27.17 ea, coil packs £81.92ea. Appreciate any advice. All for 2005 DB9. Cheers Craig.

There are now improved versions of the spark plugs available for both the older cars (would apply to your 2005), and thr newer bosch engine mgmt V12’s.

This video is very useful to watch and has links to both improved types of plugs.

Aren't they too short?

Yes, you re use the boot an conductor from the oe coils, pull the boot off, apply a bit of wd to the end of the spring then gently twist the spring in its unwind direction and it will come off the spade connector on the bottom of the coil, I re used my inlet gaskets as the rubber rings were still soft and in good condition, if your doing it have a look at Aston 1936 website , there’s an excellent step by step,
