Best oem intercooler for HDI

[tigerstyle]

not sure you even need a cooler that big on a small engine? my 2.5 makes 180 bhp on one about a third the size.

PD150 golfs run 2 bar through one about a third the size too!

It was cheap and  I fancied a challenge, if you're going to cut up the front of your car you might as well do it properly! 
and lets be honest, an old 306, not worth much so not much to lose!
