What plugs for an XE?

[Mazz]

As above, got a slight mis-fire (haven't they all atm!) which hopefully will be plugs as they are the original ones I put in about 5 years ago...

I've seen Spudly and Mieran's thread, and say to fit some NGK's 3330's / BCPR7E which seem to be the same :tard::confused:

Are these them, is the 'v grooved' thing ok? 110861640837

NGK iridiums if you can get them in the right thread/depth, absolutely fantastic plugs. I know of a set that have been in 3 different performance engines over 2 years, including dyno set ups etc which normally kill a couple of sets with bad fuelling/odd temp ranges, and still going afaik!

Little bit pricier but most people will sell the car before they need another set!
