It's really easy mate, i done it last week.

Bumper comes off and you remove the old side mount. You should have got 2 brackets with the Inter cooler - they go on to the radiator brackets. Loosen the screws and push the radiator back a little.

Then all you do is connect up the pipes.
 
Does anybody knows will Forge piping kit fit on my 100pd, since i already bought Seat sport fmic, cuz people over here in Croatia told me that Forge piping kit is just for ibiza 1.8t petrol.
 
hmmm would have thought it would be the same as the pd130, but im guessing. maybe email them as the will have a kit somewhere for it
 
They told me they are not sure is 100pd same as 130pd a guess it is same thing cuz piping must be same,does anybody knows is piping same on 100pd and 130pd ?
