Has any eles ruined a set in 75 miles and a visit to the pod, had to change them yet again today because off a misfire, can any one recommend some better plugs to put in it
cheers
4x4 saph

 

Like I said earlier mate, I fitted a set in my saph and it didn't even make it out of my mates driveway!!!

I know there was a dodgy batch but whether there are still
some knocking about, who knows?

 

i have
if your cars overfuelling at idle it will kill em staright away.
ive got denso iridiums in there now and even tho its still over fuelling a bit the plugs are fine. but im on wasted spark so that helps clean em.

 

I've just put some in mine and it cured a misfire on boost but it's early days lol

 

fixed mine too, was fine at the pod but today the first day i have drove it properly it was worse than ever, can u gap them because they have a funny tip ?

 

Yeah gap them to .65mm at a 45 degree angle

 

do u no what they r gapped at out of the box ??

 

Nope, could be anything to be honest if they have been knocked about. It's worth checking and I gapped all 4 before putting them in and the gap was too big on all 4 so I'd guess at .8mm

 

They come out the box at 0.8mm

 

i use the 4x4 platinum plug never had any problems with them and there well overdue tbh , James at msd said they are a good plug , stg1 only tho

Mike

 

i have them in mine and they last me ages, race after race,

could be worth getting your set up checked?

 

No problems in mine with 2 bar of boost

Steve

 

they are shit, mine miss fired straight out the box, waste of 12 quid
