what performance gains will i see from the pikey mods, if any??

Nil. Its only value is in delaying the onset of heatsoak. However if you take your car on track or push it hard on the road you may be grateful for the extra cooling.

HTH

I would say you don't get anymore performance just not the drop off due to heat.

ordered my vent from audi, pickin it up tomorrow so ill let ya know what i think when done.

Why didnt skoda do this anyway?

I'm sure I heard the Ibiza already has this done as standard?

Power should be up to almost twelvety hundred BHP at 3rpm

On a hot day. In the twisties...

Don't use insulting derogatory language.

Anyway, everyone knows you can't get a caravan behind the SMIC of a Fabia...

... Now a hamster on the other hand ...

Just take the cover off the intercooler, near side fog light. Then try it before you buy it................
