VY Spark plugs, HELP

[benhaines]

Hi guys my vy's ideling a bit roughfly every now and then when cold, told it could be spark plugs, so i followed the advice on the forums and brought 6, NGK BPR6EFS15 spark plugs, and am wondering can you just put them in, or is there a little more involved? do you have to adjust the gap? or are they good to go?? thanks guys

They will generally be very close, if not exactly, set to what you need. If you don't have feeler guages, you would still be reasonably safe to put them in as they are. Just check that none have closed up the gap in transit.

There usually OK unless they have been dropped. I'd use a spark plug guage as feeler guages can sometimes not go in straight. Just use the spark plug guage and select the size below and above the one below goes through, the one above doesn't means they are OK.

As well as sean880's answer, you should be able to find the gaps on the sticker in the engine bay on top of your radiator area. It will also be listed in your vehicle's manual in the technical section from memory

, Easy , the gap is 1mm or .038 " ( or 38thou feeler gauge) V6/superV6/5.7V8/6.0V8.

Most NGK's that are specified for these donks come pregapped but its worth the 5 mins it takes to check them JUST in case!!!!!

colgf, They are not 1mm for a Super 6. It's 1.3mm for an L67 (Supercharged 6). And 1.5mm for a V6. The Gen 3 V8 also takes a 1.5mm. Definatly NOT 1mm. And also not the same for all engines!

Then Gen 4 V8 has the closest gapping to 1mm, but that is 1.1mm.

Thanks for info, 1mm is for NEW plugs. After about 3 weeks in the vehicle they are worn to around the 1.1 / 1.3 mark. Never set NEW plugs to the makers specs, always go narrower......
