New plugs, Coils sitting proud

Hi all

Feel a little silly asking this question so apologies in advance.

Have bought 4 new NGK BCPR7ES plugs, the main coils on cyl 1 and 3 have gone back on neatly but 2 and 4 are now sitting proud having "clipped" in (approx 7mm proud).

I bought the 3330 variant having followed advice on a well known suppliers website but I'm now thinking I should've gone for the 1272 and that they have a slightly shorter overall length.

Can anyone confirm this or point out that I've done something very stupid before I shell out for another set?

Cheers in advance

Very odd. Are you sure they are pushed home properly.

Pretty sure they are, putting a fair amount of weight into it, I just get the 1 seating "click". The plugs that came out were the OEM champion nlp100290 jobbies, they measure 5mm less overall length. Thread dia, length etc are the same as these NGK's, the extra length comes from the top half of the plugs...

Sounds like you have answered your own question.

No not really, my original question was, are the 1272 variants a shorter length? This, before I buy a set and find out that they too are too long. 
 

Cheers.

Following as I've also seen this on VVC engines with BCPR7ES (3330).

Could they be copy plugs from an unknown source ?

Mine were from Euro Car Parts so should be genuine.
