Verified Buyer
Bought Boost Tube upgrade kit 25936.
Should have done more research... kit only comes with the upper silicone hose and 1 clamp, not the lower. After looking into other kits, found that the HSP kit comes with both hoses and clamps for a couple dollars more. I tried to exchange it for HSP kit but it was going to cost $100 to ship back to XDP and a 5% restock fee, so I guess I will keep the pipe and find a hose and clamps to make it work. Factory bottom hose is permanently clamped to stock pipe so a new hoses and clamps are needed. Probably my own fault for not paying attention to what I was buying but it for sure is an incomplete kit.

Banks power boost tube upgrade kit
Ordered the boost upgrade kit, the pipe came but the rubber boot an clamp did not, I immediately reached out to the customer service section. The situation was handled an I had my boot and clamp in hand 2 days later. The pipe went right into place an seems to be holding well. Order number: 2441051
Worth it
Got this tube along with the banks technicooler intercooler. Temps are down across the board. Spools faster. Sounds better. 2-3 more lbs of boost. I believe it flows more air through the fins as well because my Coolant temps are down as well. Not sure what gains come from the tube and the cooler, buy both and you won’t have to wonder. Transaction was easy, got the parts in 3 days with free shipping 1500 miles away. Order number 1491322
