Just by chance I replaced the spark plugs yesterday, Just a query really as all 6 plugs condition were of a brown colour, does this seem a normal colour?.

light brown you hope.

as long as its not totally white, or totally black you should be running ok.

dont suppose you know how old they were ?

Hi I would like to know how you got the 2 centre plugs out

 

[mikey magic]

light brown is most likely to be the cause of optimax or octane booster. this does make the plugs go brown.

:funny:
Light tan is normal,in all road going reciprocating petrol engines
The centre plugs can be removed,with care,without removing the inlet pipework...or just remove it,easy enough..
