Desno IK20 Spark Plugs - Should I Change the Spark Gap?

[MarkyB]

'scuse my ignorance, but do I need change the gapping on Denso IK20 Spark Plugs or leave them at the factory setting?

* I searched the forums, but I guess it must be one of this things that everyone else knows except for me

Cheers,

Mark.

Why IK20's?

IK22 would be better for a remapped car, as they are 1 heat range colder, and most people leave them at standard gaps.

I have no experience of IK20s, try searching ukmkivs.net, I know a few run Denso's on there, but like me, most run IK22s.

IK20's are the equivalent replacement for the OEM NGKs, I'm on the standard 210BHP so not much point in spending extra for a colder running plug.

I have bilsteins + tiebars + bushes, followed by 4 new tyres on my todo list before I even start thinking about a remap...
