Put this on 2011, 4.7L Dodge Dakota (website and instructions only to 2010 model). Figured since no body style changes, there probably weren't any engine modifications either. The only real problems encountered during installation were vacuum hose port not in right location on new intake and original sensor location on engine not long enough to reach intake location for it - had to lengthen both the hose and sensor wire! Hopefully this will improve mpg - too early to tell as vehicle new and it's running more here due to Winter warm-ups.
4.7 HO Dakota Review
Install was simple, only took a about 30 min. Everything made well and easily mounted. Only small issue was the MAF sensor mount which was just a piece of rubber hose was the wrong size, i luckily had the right size laying around so no big deal. I got the Wrinkle black, no need for the shiny intake under the hood imo. It looks good. As far as performance and such. I have had in on a few months so i could get a good idea of the mpg. With my mix of highway/city i was getting about 15.5, the average after a few tanks was 16.3, so i gained about .8 mpg which was about my expectation. I recently added a MBRP catback and got the mpg to 16.9. I would definitly reccomend the combination of exhaust and intake, it really makes it run much better. This is better than the stock restricive air box, the engine breathes better and trys less on the highway. Throttle response seems a little better, but performace is always hard to judge with something like this. You can hear it sucking air a little bit, but that is expected with an open filter, does a nice slurp downshifting 3rd to 2nd. I've had great luck with AutoAnything and haven't found better prices, hope this review helps
Good and Bad
The good: It looks great. it sounds great - quite under normal driving but mean sounding when your on the gas. Most importantly, it gives me more power where I needed it. I often found my Dakota dogging up hills with a full load. This intake definitely increases the pull under those conditions. The bad: Injen did not do their homework for the Dakota. Mine has the 45RFE transmission and the intake does not fit. I had to relocate the vacuum kickdown canister and fabricate a new bracket to hold it. The filter also rubs against the TCM, so I need to buy a shorter filter. I positioned it so it is not too bad, but still the filter should be shorter. These problems turned what should have been a 20 minute job into a 3 and a half hour job. After I encountered the problems, my research found that the AFE intakes include brackets for just this problem - I guess they did their homework. Conclusion: If you have a Dakota without a 45RFE transmission, I would highly recommend this intake. If you do have the 45RFE, your money would be better spent elsewhere.
