strange spark plugs
« on: September 08, 2007, 16:06:29 »
Just changed the oil & filter on my P38 4.6 and decided to chuck in a new set of spark plugs since the originals have been in since it was shipped from Japan last year
The plugs that were in it were NGK BP5EVX which I have never heard of and they had a tiny pointed electrode tip
Using google, these plugs seem to be platinum tipped racing plugs for motorbikes ? - over a tenner each on ebay !
Anyone used these in a Rangie before and is there any advantage over normal (champion) plugs ?

IIRC the normal setup is BP6ES, or optionally the 5s?  Not heard of these ones.

Yeah - that rings a bell, just wondering why I have ended up with motorbike plugs in my Rangie  :?
It seemed to run fine with them in mind

If they're that expensive they MUST be good!  You could always replace them and keep them as spares.

BPR6ES is the specified plugs -the 'R' is not THAT important, but will make a difference :)

BP6ES. or BPR6ES

The 6 is the heat rating, so that's important.  One of the letter is the length, one the thread etc etc.

The R stands for resisted, cuts down radio interference but if you run LPG you're marginally better off without it.

If they are platinum (I'm guessing the V) they won't work too well with LPG I'm told.

I fitted BPR6EIS Iridium plugs, costing typically £8 each, I was very smug when my local factor got me 8 for under £50.
