I'm looking at them too. I see kits with a "T" and kits without. Is there a performance difference or is it just preferance. Also there are DIY kits you can put together yourself, is there a downfall to these? It all seems pretty simple I think.
Mike I looked up and down for your write up on this, and cant find it anywhere?
You can do it yourself, but it looks just like "you did it yourself." Or get the kit, which looks much more professional and is a much cleaner install. I also got the allseasonsdiesel kit. Mine does not have T's. The PCV reroute kit prevents the leaky oil buildup in the factory blue turbo boots.
I'll have to go digging Chad to see if I can find what I posted. It wasn't in a DIY thread though. I pretty much used the instructions with the all seasons kit. you can look at them ahead of time from his site too. It's a top notch kit.
