how do u close up the gaps on a spark plug, thanks

 

anyone???

 

Just tap them on a hard surface.

Nice and gentle to ensure you don't damage them, close gap to far etc and obviously check the gap afterwards with a decent set of feeler guages

Assuming they not iridium plugs which you not supposed to alter gap

 

thanks thats what i was gonna do. just making sure

 

whats that gurE? (not altering gap)

also what ARE ridium plugs? (compared to normal ones)

always wondered
