I've also heard that the flexible lines develop leaks over time, maybe because they run so close to engine heat where they come off the sandwich adapter.
Based on your username, is this going in a Jeep? For an off-road vehicle that runs at high RPM and low road speed for a long time I think the external cooler would be worth it. However, its probably not needed on a street vehicle.
Thank you for the replies guys, they're so much apprecciated...
Yes, cooler is for a Jeep and will spend a lot of time just off idle so it's not gonna get too much air at low speed...
I'll look forward and get a nice sandwich adapter with a cooler.
