I have a 2020 RCSB 5.0
Any suggestions on an Intake? Looking for best performance option

 

S&B. Priced right, Sealed and works great.

 

Yep, S&B is a nice one, I have that one as well. As far as performance, you'll be disappointed, unless from what I've seen, supposedly gives you a couple horses up around the higher end of engine rpm. Looks good, and sounds good if you remove the clear over, but then you'll be sucking in hot air from under the under the hood.

 

I was thinking the airaid one because it looks cool lol or maybe just a custom 3.5-4 inch might work best

 

I had an Airaid on my '12 5.0, it looked and sounded great, but being an open top, even with the seal, no doubt it was sucking in hot air. That was one of the things that drew me to the S&B. Actually, the OEM system is plenty good for most of our trucks, but ya, there's cooler looking ones out there..
I can tell you one thing, even today with a 65F temp, at 55 mph, I was reading 97-100 temps on the IAT2, IntakeAirTemp. That sensor is at the rear area of the intake manifold. TBH, I never saw what the temp was with the OEM intake. One of these days, I'm gonna remove the clear cover, and see what I get then.

 

Id say a Gen5 3.0l whipple. get plenty of air what that thing.
