Look at the stock intake tube vs smooth aftermarket. Factory flow is slower and turbulent. 52mm is good with the better exhaust and roller rockers as I stated earlier.

 

The only difference in power you would see is in the upper RPM range, where the smoother tube would give better flow. For 99% of driving, the aftermarket cold air systems don't do squat. Certainly not enough of a difference to justify the cost.....

 

Hey, it's like back in the 00s when everyone's latest "mod" gave them at least 50 more hp. All our little Magnums were cruising around with more total HP than the Hemis! Hahaha

Don't forget the KN sticker! That's a quick 5HP!!!

 

O.P. did not specify r.p.m. range or if cost was worth it( which is entirely subjective). He asked for 50 or more h.p. without tearing apart motor. It can be done. A tune will at least get rid of the death flash and prob about 10+ h.p. by itself.

 

When people talk about more H.P they are telling about it in the useable range. Plus $200 for a CAI isn't "low cost" especially door little too no gain

 

Yep. What the Fanatic said.

Folks looking for more power are looking for USABLE power. No point spending money on parts that are intended to work in an RPM range these motors weren't even designed for.

I agree though, getting rid of the death flash, and reducing torque management, is definitely worth the time/effort/money involved.

 

Seriously? You two don't think you can add 50 h.p. without a power adder or tearing the motor apart? You keep saying no.... yet rockers are easy, tune is easy, exhaust moderate, intake easy, e-fan easy. You disagree, fine. Instead of telling everyone "no" can't be done and being extremely negative, give us your suggestions? Any dumb *** can sit there and arm chair qb. How about give the o.p. some positive info.
If I hurt your feelings.... ban me.

 

I'm saying it can't be done cheap. If it were me I would go headers and true duals (at least $600), tune ($300), rockers ($180), and a cam ($250). None of that is cheap and easy like the OP wants.

It's like me saying I want a 800hp V8 car that runs and drives and is street legal but I only have $3,000 to spend. It's impossible.

 

Throttle body spacer adds like 50hp.

 

The question was "50 to 150 horsepower"..... Tune, exhaust, rockers, and intake might get you close to 50...... But, not cheap. I think the fanatic underpriced several of those. Rockers are more like around 300, intake is 600, exhaust is likely the same. (for a complete system.) I haven't seen a cam for under 300 bucks in quite some time, and that is JUST the cam.... then you need springs and such to make it work. (or, lower your power expectations.) If you REALLY want to get north of 50 plus HP, then you are looking at heads as well..... so, 2-3 grand for better-than-50 horsepower. Not inexpensive. But then, horsepower is rarely cheap.

Wanna spend less, and get more power? Pick up a used hemi, and adapt that to the truck.
