Cold Air Intake

Jettech1 · May 5, 2023

I just want to add, if you are going to spend the money for this mod (and I do believe there are way cheaper ways to do this). Put that rubber plug in on the side of the intake box. I'm telling you all, it went from sounding like trash to one of the best sounding intakes I've ever owned. Seriously....I know it's been kind of a fiasco up to that point but I'm telling you, it sounds amazing!! If I had a do over. I would probably grab some rubber 1" plugs, drill about 6 holes in the front of the factory airbox (below the filter of course) using a 1" hole saw, throw in a flat panel whatever kind of high flow air filter and adjust the sound and flow using the rubber plugs. So there's your tip on how to save money and make it sound great. But damn, the way it is now is definitely the best sounding intake I've ever had. And I'm not saying it will sound like mine just by drilling some holes in the intake box....it may or may not because the setup I have eliminates that huge whatever it is in front of the throttle body. Just FYI all.

Stillen has a air scoop to replace OEM at the top of the grill. Helps direct more cool air in toward air filter box. I haven't gotten it yet, but will be getting it down the road.

Interesting. Please keep us updated. This might save many a lot of money down the road.

Would be interested in a before and after of towing with this set up. I'm guessing without a load, the engine being torque sensing, is defeating any benefit.

Did any of you gain any fuel mileage after installing a cold air intake.

I'm thinking of an S&B for my 2023 with 6.6 gas

I have a 22 2500 gasser that I installed the S&B on and the answer is a resounding NO! If I had a do over, I would have left the stock intake on it and saved myself 350 bucks.

Thanks for the quick reply.

I think I'll save the bucks too and stay with stock,

Much appreciated

A few years back motorweek did an analysis on cold air boxes. The results was there can be improvement in mileage. The conclusion was you probably won’t keep the vehicle long enough to get the advantage. Most of my life I didn’t tune my vehicles, add cold air and put loud exhaust on for any reason other than the chance for improved performance. My butt and ear said, yea baby! From as far back as adding a 4 barrel, duals, and a B&M shift kit to the early Chevy truck engines. Sometimes even changing the rear gears. That was my goal. Gas mileage improvements? That happened too. Especially in the early days. Did I care? Not a bit.

@Randal Scottdid you ever get this? details?

Edit: Why would you run this on a gasser if the intake doesn't take air from there?

On a gasser this is where it gets it's air from. As long as you have a closed cold air intake in the OEM position. I didn't get one of these. I looked closely at theirs and modified my OEM to work about the same. There is a post on here showing what I did.
