NGK IRIDIUM Spark plugs - brand new, boxed

[summeh]

Bought these and never used. they are TWO grades colder/harder ( 8 ) than standard ( 6 ), so ideally for modified engines, altho will run fine in standard.

I did actually run them in my car for about 1 minute when I was trouble shooting an issue, then put back in the box and never used.

They are NGK IRIDIUM tipped spark plugs, two grades colder than normal. Will fit 16v engine (inc williams). F7P/F7R, probably many others.

Iridium plugs have a service life of 72,000 miles. The tip is just 1mm across so you get a much better spark. So should give better performance

These are 30quid inc delivery and vat from spark-plugs.co.uk

I am asking 20quid delivered to your door.
