I just got a JLT intake and installed it tonight Previously had the Gotts mod and K&N intake. Installation was a piece of cake. Take off the factory intake and tube and slip this one onto the TB, tighten a couple hose clamps, and you're good to go. Had to reset the battery, but thats to be expected. The quick test drive I took showed temps to be 4-10* warmer than ambient while driving. Where the factory intake was about 6* warmer, so not much difference there. Parking lot and idling showed an increase of about 25* though, so this may not be for any of you southern boys or anyone with traffic jams. The noise is much louder! Don't really notice it till 3k rpm, but then she howls!!! Some people said the gotts/K&N made a noticeable difference, but I never heard any over my cherrybomb. This I can hear! I'll get pics of my truck up tomorrow and do a report on mpg after a couple tanks. Here's some google pics
