Anybody know the stock TB size? Just recently bought my truck and found it had a cai and catchcan. The TB looks ported to me, so I measured it with digital calipers at just over 83mm. Was going to get a Moe's 87mm, but not sure if it's worth it now?

Haha, sorry,uploaded the wrong one. This one probably isn't much better, but that's all I snapped when I was in there. Forgot to snap another one when I took it back off to measure with the calipers :slap: . If need be, I'll pull it back off tomorrow to get better lighting.

The new throttle body, standing alone, will probably not make a significant difference in your performance. If you also add a aftermarket exhaust, a CAI and a tuner with a custom tune to your new throttle body you will notice an increase in the performance in your truck.

I have a Moes 87 mm throttle body, I did it at the same time as my grannetelli hot street coil packs but they did make a noticable difference.

I'm surprised to not find any aftermarket intake manifolds. Do these come with the eagle intake manifold? My previous vehicle was a 2011 300C, I know the eagle intake manifold was something that came later stock to squeeze a few more ponies outta the hemi.

Yeah? What are the claims? I know when the eagle intake manifold came out, people were jumping on them for $1200 just for 15 HP. It was stock design in 2013+ I believe. But keep in mind, I believe a cam wasn't available at that point lol

The intake manifold is different between the trucks and the cars. The truck manifold is taller and is an "active" intake.

You got all the goodies(well a lot of them). You should see a marked increase in performance. The headers will also give you a pretty good boost also. What gears do you have? You might check with Matt at Moe's Performance about the intake.
