K&N or SB Filters cold air intake

Meaning if the stock airbox can move enough air to feed a supercharger it can move enough air for a na engine.

The Oem tube on these engines isn’t restrictive ether. Doesn’t have the large baffles and chambers like a lot of other manufactures.
 
Everyone's a comedian. But any excuse to post more pics is fine with me. 😁

Yes, funny. I still don't know what the special good looking thing is, nor would anyone that's never seen the engine bay of a RAM 1500.

Is it the hump on the top of the engine?

Sorry, I didn't realize you were from the HD world. Here are pics with the stock intake from my previous truck.

Yes, they absolutely do. I've had K&Ns on 3 Hemi trucks (5.7 and 6.4). Noticeable sound as well as throttle response improvement and slightly better mpgs.

I have an S&B to install tomorrow morning. I went with it for a change, hopefully I'm as happy with it as I have been with the K&N.
Let sus know how it’s been with your S&B. Which one you like most, and Why? Thanks
 
Considering he thought the other ones made a difference. I’m sure he will say the same thing.

Has anybody measured intake air temp before and after? The primary purpose of a "cold air intake" is to lower the IAT so you get a more dense air charge and theoretically, more oxygen to the engine. That's why boosted engines are intercooled, to bring down the IATs. Increased flow is worthless if you're just sucking more hot air. In addition, more flow in = more flow out. A CAI by itself only separates you from your hard earned cash, to see any effective gains you'll need to address flow out and fueling....in other words, headers and a tune.

I've seen this same debate over CAIs on Chargers/Challies. The OEM air box on my Scat runs 7-10* above ambient in clean air. No CAI, no Hellcat air box mod, just the OEM box with an OEM filter. Most of these CAIs pull air out of the engine compartment where everything gets heat soaked, especially on the LX cars. The only CAI that makes any difference at all (maybe 2-3*) is the Legmaker that routes the filter out of the engine compartment and down behind the L/F headlight.

Almost everything I've seen on the market for trucks these days pulls air out of the engine compartment to some degree, with the exception of maybe the Vararam. The last real CAI I saw on a full size truck was the old Scotty II we used to run in the 2nd Gen diesel days. Long filter and an "air box" that required a 4" hole in the firewall to pull air from the low pressure area at the base of the windshield, right under the plastic cowl.

Save your breath dude. They aren't listening. I promise..

Actually guys did (for the Hurricane), the K&N, because it is drawing air from the engine bay was showing around 199 IAT, which is insanely high over the factory of around 120ish. But yeah sucking in engine bay air is a terrible idea. The S&B, usually, will not draw air from the engine bay, so that IAT should be very similar to stock. With a much better sound. Why do people think the reason people and intakes is for power gains, it isn't, it is for the sound..which is 100% noticeable. People buying intakes for 'power gains', need an examination.

The factory intake is a cold air intake because it pulls air in from outside the the engine bay. You can't get colder than ambient, and on 5th gens the intake air is pulled from the grille area, in front of the radiator support near the passenger side headlight.

I definitely didn't buy my Vararam for sound. You buy an exhaust for sound, not an intake. While intakes do allow you to hear engine sounds more that's not the sound you want to hear, you want to hear your exhaust. I got my Vararam primarily for looks, as IMO, it's the best looking intake, and secondly for performance, because it's about the only aftermarket intake that gives verifiable gains. And yes I did verify with my TazerDT 0-60 timer that it did help with performance.
