Thanks Mudski. Did the MAF sensor yesterday - got a bit of dirt off of it but it didn't look to be very dirty to me. I took the plastic cover off from around the intercooler and as per the photos - it's obviously not airtight anymore!! So it looks like I'm in the market for a new intercooler - I see that Patrolapart has a basic unit with welded end tanks for $675 or they have a HPD one with a thermo fan for $1275 - have you had any experience with either? Is it worth spending extra for the HPD version?
