I don't have a JLT intake tube, but do have a densecharger with a Steeda STB and with the upbend it has gives more room for an intake tube. With the stock NPI lower and/or upper intake, the fit is no problem. With the trick flow plenum (raises height) and PI intake, I had to buy an adapter from the local auto store for it to fit without hitting against the STB. Hope these pics help.
With the stock plenum
Here it is before I got the new adapter and hopefully you can see the bulky elbow connection and the how the STB leaves room for clearance.
Here it is after the new adapter.
