I lied ,the other day I saw Bosch plugs 4 four AU $37.50 at super cheap
here in Melbourne .They had 4 earths and a small centre pointed in such a
way that they should maintain their gap for a long time ,100.000 KLMS I was
told .I used such plugs on an Alfa I once had they made a huge difference
..so I will see .By the way number one plug was a fair cow to get in right so
they havent changed their ways ,they still jamup in the treads .
