Spark Plugs

sebastianlieken

Hi all,

I want to change the sparks in my golf because as far as i can tell from the service history (at vw) they've never been changed.

the car is a 2008 Golf MkV 1.6 fsi, engine code : BLF

I'm trying to find the right spark plugs to put in but i'm getting a bit lost in the technicalities of them. I know that the gap distance is vital to an efficient spark, but I don't know what the gap distance is for my engine?! (I dont have an owners handbook)

• on the NGK website here it gives ZFR6S-Q sparks with a 0.5mm gap.
  
• On eurocarparts here one of the recommendations is a Bosch plug that specifies a 1.35 / 1.4 mm gap.
  
• On the Bosch website itself here, it too specifies a 1.35mm gap with their plugs.
  
• Amazon here throws up the NGK plug aswell for a golf 1.6fsi BLF engine code but doesn't specify a gap
  

And then there are multi prong earth sparks and single prong earths. I have a set of feeler gauges so I can change a single prong, but not a multi prong I guess...

and then are copper cores the ones to go for?

I am confuse.

not sure if this is a stupid question or a difficult question...

Take the old ones out , bring them to a motor factors , or give a local dealer a ring a ring for the correct OEM ones

demanufactured

Plugs come pre-gapped no need for feelers guages anymore.

True enough but that said you'd be amazed the number of plugs I've removed from the box to find the electrodes bent and require gapping. Perhaps a friendly parts man at VW will be able to give you the correct plug type. Indeed OEM service items are often not too much more expensive than spurious ones, plus you've the confidence that precisely the correct parts for your car are eing fitted...

They are very badly worn, You'll find a world of difference with new plugs, economy and performance wise.
