Spark plugs

[paul pierotti]

Hey guys i think i have a few problems with spark plugs i feel the car isn't running as good as i would like at the moment and relised im using the same plugs i had before the rebuild and are not in the best condition. So i took one out and went to fetch new ones but i remembered henry roy put motor bike plugs in it when he serviced it one time and was wondering everyone thoughts on running theese plugs. I seen on the forum nkg-pfr7g-11 are type r specific plugs would people agree and wheres best to buy plugs

I don't know the reasons or advantages for fitting bike plugs but there's maybe a reason. That or Roy's lost it completely now.

Common misconception with plugs is that iridium/platinum tips are performance plus. They're not. The materials are used to increase service life not performance.

If that's the manufacturer recommended plug you shouldn't go to far wrong with it. Depends on set up really but on a relatively stock/lightly modded engine you should be fine.

I got the impression at the time that basically he loved to fire bike plugs in everything lol

The ngk plugs that you mentioned I've used for the past 3 services on my em1 and have just bought a 4th set. I know it's not a Type R but it's still a B16 so these will do a job
They're so cheap replacing them every year isn't an issue. Like Rob said the iridium plugs are for service life anyway. At a third of the price you can't go wrong with the ngk 11 plugs.
