I'm curious, besides making the engine bay look amazing and possibly lowering EGT's(not sure how, but that's what is being advertised) Why would someone replace the intake manifolds on the 6.7 with something like......the Pusher kits($1,439-powder coated), Smeding kit($1,099)? Running basically stock beside a tune, what could I be gaining for the money spent?

I ask because I was thinking about a cold air intake, but a good one is pushing $400+!! So i thought why not just do the entire intake for twice the cost......but is it worth the money?

Thanks in advance for the info.

And if you have any personally experience or recommendations let me know!!

I wouldn't recommend running a piping kit on a "otherwise" stock truck. In the end it's about creating a better/smoother path for airflow. Tuning advances timing, air needs to be there ready to flow into the cylinders.

Stock mode: The turbo is trying to suck air thru a itty bitty straw......
Aftermarket air filter/"intake": That straw is now two times larger (or whatever) the turbo gets good air......but that air has to get to the cylinders....so we need the best path to get there.
Piping kit w/Pre & Post turbo piping: Now that "straw" is four times larger. Smoother piping (hence more direct) allows that turbo to get the air to the intake manifolds.

Want more???
If I had bigger pockets I'd dump money into modded intake manifolds and the exhaust manifolds. It's just not easy to swap it all out, takes time and definitely need to have money as a back up plan. LOL

Add to that straight piped exhaust......then you just need a good tune to make it work perfect.

If your running a straight pipe w/tuning is it worth it in a towing situation? You think? Thats pretty much my current situation

A piping kit would/could eliminate the classic "plastic CAC tube blow out". This is when the CAC outlet side piping (plastic) is stressed and gives out. Tends to be very audible and not easily missed while driving. Does cause an OhShetz moment...can be fixed roadside but not for long term driving. In the end most people do a upgraded CAC out pipe with no further issues to report. Just a bit PO'd over sitting on the road side making a field repair then getting the pipe swapped out.

I'm always on the side of running mods, but one has to weight their own priorities. DOT issues??? Maybe stay stock. Recreational towing or towing your own equipment you could be enjoying the ease of the new power/torque.

I've towed plenty with my mods....never concerned with the new capabilities.

Ive read about the plastic CAC blow outs. I guess im getting sucked down the rabbit hole haha, I dealt with my EGR and DPF and told my wife that was it just to hopefully help with longevity(as she shook her head haha). but then you hear how the truck really sounds 😀..then i thought about getting rid of the throttle body cause i was worried it might somehow close(even being unplugged) and at the same time get rid of the plastic CAC (get two birds) Theeeeeeeeen I started seeing the full pipe kits that would "DO IT ALL" haha and look good while doing it.

I guess im here trying to justify it in my mind haha you all know how that goes.

Btw, all my towing is recreational, and private work. I wouldn't think DOT would bother me unless i was being an idiot rolling coal.

Thanks for the responses Btw

I'm partial to No Limit. They treated me right with all my stuff. I will say you get what you pay for. Just ask questions before you decided with whatever brand. I can suggest asking about additional ports in the main tube so you can use a boost sensor to see the PSI as it's traveling to the manifolds. My MidWest piping setup has two ports that I use for boost and air temp in the piping. Not to mention using a No Limit intercooler with it all.

Open elements.......well....I'm not a good example for people to follow. I've never changed my No Limit filter over 160K miles of driving since I installed their stuff.
Still running the stock turbo, no issues. Just oil, oil filter, fuel filters, fuel, and driving it. Truck does what I want, when I want, for as long as I want, without question.

I made sure to get a pre-wrap on the filter so is that why it works????? Can't say for sure.

Intake air temps generally run 15-25*F above ambient....So if the OAT is 90*F I see air temps post-CAC in the 100-115*F range. Running on the HWY as long as boost PSI stays below 5lbs PSI, the intake temps stay within that 15-25*F above ambient. Towing while holding boost over 5lbsPSI.....those numbers stay higher. Does the truck know.....not a chance. Just keeps running down the road.

See what happens at idle......IAT is read from the MAF. ITAKE TEMP is the Edge Performance sensor in the piping leading to the Y that splits to the intake manifolds.
AMB TEMP is the OE sensor in the passenger side mirror which feeds the Sync NAV display as well.

This is on my list of things to knuckle up and buy one day, I will probably go with the MPD kit there all about the same in price within a bit from each other, the fit and finish of the MPD kits I hear are worth it.

I really like the pusher kit, but you have to buy the hot side charge tube separate, kindve annoying they don't just include it with the rest of the kit. And I don't like that the filter pipe is two piece. The MPD is nice and really expensive haha
