Barely used NGK 3330 Grade 7 plugs

Not sure if anyone is interested but I have the above available. They have only done about 200miles if that since I changed them out to put some Iridium grade 8 plugs in.

 

They have been gapped by a professional so no need to worry about that.

 

Might make a nice cheap serviceable item for someone.

 

Say £10 posted.

 

Can take pics of them if necessary.

No you can't, its why all the iridiums in the FAQ section state to leave the gap alone and the manufactures tell you not to do it. You can damage the elctrode which is why its not recommended.

Even your qouted website says you can! It just says it's not usually necessary and you have to be careful! :rolleyes:

 

 

 

Q.Do I need to set the gap?

 

 

A. Generally, no. The DENSO Iridium Power plug comes pre-set with a protective sleeve over the firing end, to protect the gap from accidental alteration. DENSO Iridium Power’s ultra-efficient firing power compensates for normally recommended gap settings that are smaller than the pre-set value. In the cases of vehicle modifications (nitrous, turbo-chargers, super-chargers, high power ignition systems, etc.), some adjustments may be desired. Or, if you prefer to remain consistent with factory specifications, you may adjust. However, please be careful not to place any stress on the fine center electrode during adjustment. You could accidentally break off the very hard, and therefore brittle, tip.
