I finally stopped overdoing my intake spacer after a dyno day
I was running a 3 inch spacer on my 2018 5.0 for over a year because I figured more air was always better. A buddy at a shop in Phoenix told me I was losing low end torque by pushing the intake volume too high. You ever get feedback that made you totally change your setup midstream?

That 3 inch spacer is probably killing your torque curve on that gen 2 coyote. The factory intake manifold actually flows pretty well on those cars without adding that much volume. A 1 inch spacer would give you the intake temps you want without choking out the bottom end.

Ha! Yeah I learned that one the hard way man. I put a 2 inch spacer on my old gen 2 and it felt like I was driving a Honda Civic with a clogged exhaust below 3000 rpm. The car would just fall on its face leaving a stop sign. I felt real smart watching that dyno graph look like a ski slope. Now I just run a 1 inch and call it a day. My car actually feels like a V8 again instead of a really loud vacuum cleaner.

Phoenix is right about that 3 inch spacer being too much for a street driven gen 2. The extra volume messes with the runner tuning and kills low end where these cars actually make their power. I've seen dyno sheets where a 1 inch spacer picked up 15 lb-ft down low without losing anything on top, plus it keeps the intake charge cooler without the drivability issues. @phoenix_thompson4 if you ever get a chance to look at the runner length math on those factory manifolds, it's actually pretty impressive how much work went into them from the factory.
