Quick question or two - I know that these plugs are sometimes sold as single units (as they appear to be on the ebay link) as they are used in motorbikes. However, I think the bike plugs come with a different gap setting. Is it the same for these or are they preset to 0.8mm like the 4-pack?Also, there was a post or two about some folks reducing the gap from 0.8 to 0.67mm or something like that on tuned cars. Is there anything behind reducing the gap (as there is a big danger of damaging the delicate tips on these plugs?Quote from: Tfsi_Mike on December 18, 2011, 10:50:48 amThe pad damper I'm talkin about ^^ I managed to source 4 of these for my NQSBBK as I was unlucky enough to get a bit of low speed squeel although it may have been a combination of discs, pads and not being broken in enough. These things fixed it no problem anyway. As a bit of advice, if you are going without the anti-squeel shims, use a non-petroleum based grease on the back of the pads like CeraTec. Copper grease rots the bejeeziz out of the rubber dust seals.
The pad damper I'm talkin about ^^
Can you take the brake talk to another thread please, I will clean this up a bit later.
I found this thread after a bit of searching having noted my car was missing occasionally at idle after a long run at medium to high loads (extended motorway run, with some B-road overtaking for instance). I have the latest revision PCV flying-saucer-esk jobba fitted.Mine's a stg-1 K03, so I'll report any improvement to add to the thread's statistics. For reference the plugs I removed are 15k old PFR7S8EG and they look in text-book condition. Whatever the outcome 4 iridium plugs for just over £20 makes them pretty much disposable, so cheers to the OP for the tip-off.
Ive noticed the same so it would imply these plugs really do make a big difference.However my MPG has improved by around 2-3mpg
Put mine in the other day and def smoother! I was running the NGK OEM heat range ''7'' plugs before.
I wouldn't touch the gapping. Mine are perfect from their purchased spec.
