Post by: GLIDN on August 01, 2010, 10:49:24 am: surely these would be the same for the ED30 / S3 and GTI golf?

Or are the ED30/S3 specific?

Post by: Dav on August 02, 2010, 12:25:19 am: Personally i'd run a copper plug going from my experience of Iridium/platinum plugs (expensive, can be the cause of most miss-fire cases on turbocharged cars)

I dont know what the Golf copper plug code is though...
Title: Re: ugraded spark plugs?!
Post by: xxx_mojo_xxx on August 02, 2010, 08:47:21 pm: OEM spark plugs are platinum ones by default...had no problems.
Title: Re: ugraded spark plugs?!
Post by: Dav on August 02, 2010, 10:02:24 pm: No you probably wont on a standard car...when you start to tune/run more boost you probably will.

Hi Dav - what kind of problems could I expect? I'm running Stage 2 and haven't experienced any issue, but that may be down to me not knowing what to look out for.

Cheers.

Post by: Dav on August 03, 2010, 05:35:30 pm: Usually the cause of high rev/boost miss-fire's, not every car has a problem but it CAN develop over time or if you fit new plugs.

I only ever use copper plugs in cars.

Post by: nc35 on August 04, 2010, 08:02:00 am: The higher the tune the smaller the gap to prevent pre ignition.

Pre gapped at just over 0.8mm you can reduce to 0.7mm for a stage 2

Hope this helps.

Post by: Dav on August 04, 2010, 07:25:22 pm: Pre igniton is caused by the wrong grade, if you have this you need a colder plug i.e. an 8, if the gap is too big the boost just blows it out also causing a missfire. ime.
