Edit to my last 1hd cooler post too...
The official 1HDT Intercooler thread
I might add that during the install I noticed Mark's HDJ80 had a bonnet scoop. When I asked what intercooler it had? he stated none...
Not very reassuring that the bloke who sold me his product, didn't even have one on his own vehicle...
How does all this testing happen if he doesn't run it on his own 80 ?
