The Definitive S2 Spark Plug Thread

0.6-0.7mm is good. I think they are pre-gapped from factory to 0.7mm.

Great, thanks!

*EDIT*

Looked at the specs of the plugs again, turns out I'm running 0.9mm.

I don't see any need for such a large gap, do as JP said above and gap them to .6mm

I stumbled upon a thread somewhere in the web, that to take advantage of the increased spark from FSI coils, a plug gap of atleast .040 inch is required.

*EDIT*
Found it - http://www.audizine.com/forum/showth...FSI-coil-packs

Is this true or I can stick to smaller gap? Currently running BCPR7ET with 0.9mm, runs like a clockwork.

[Thuppu]

Yes, I would also say 1.1 meter is little bit too big gap.

Plug change time upon me. Wanted to hear some opinions. I want to go for BKR7/8EIX-11 (1.1m gap), this is a native gap for FSI coils (which I run). Will the old 5-banger be OK with that?

^^^^^ so long they are not Denso's. I've seen more molten heads than you can shake a stick at with Denso's fitted.

I have been through about 5 sets of IK27's i would not bother with them any more

BKR7EIX from NGK gap to 0.6mm

Going to replace my plugs tomorrow with BKR7EIX- seems they are a good alternative although not much reference to stock motors . I have been scared off using the F5DPOR due to apparent quality issues and would rather not use them.

Stock engine at the moment. Would 0.6mm gap work well? Or better to leave them untouched?

[Vorsprung durch Technik]

I'm sure others will know the answer to that question,but on the face of it if Bosch were prepared to sell out to china and dumb down quality they deserve to loose market share.

[s2driveruk]

does anyone know if the issues with the stock item quality control is still a problem or was it limited to a batch or specific build period?

Thanks man!

Hi.

Who are the compatible spark for our original Bosch's F5DPOR?
I try with a FR5dp kit but I'm not very happy.

I've RS2 stage3 from PRJ

So the Iridium plugs are friendly after all.
