NGK Iridiums BKR8EIX ***12k mile update on page 13***

[alexperkins]

I do, very much 

[JackG]

There's so many different plugs out there and people rate different ones so im pickled 
Would these be "the daddy" for stage 2+ eddy?
 

[alexperkins]

I would say so Jack

[jaycue2u]

I assume these are the right type for an 05 GTI?

[alexperkins]

Yes

However if you are not mapped, it should be said a BKR7EIX is perhaps better as this is the same as VWs stock plugs.

Im running a stage 1 revo atm, looking to go stage 2 in the new year, so these ones are GTG?

[alexperkins]

Then these are perfect for what you want

I was under the impression 7's were the ones I needed for st2+ well just ordered these to try thanks for the link!

7s are VW spec, which are a step cooler

8s are step cooler over VW spec and better suited to tuned engines

Also, iridium is a better conductor than platinum which VW use in their NGK Plugs - Iridium is almost as conductive as copper, but has the long life of platinum so its win win

Will see how I get on with them. Cheers

May not go in till spring when the weather allows the engine to be worked safely.

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.

I have been running these for a couple of months now and the car hasn't missed a beat.

[JackG]

I would say so Jack

Cheers dude

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?

The 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.

Can you take the brake talk to another thread please, I will clean this up a bit later.
