14'SilveradoLT

The tube will NOT swap over to the stock air box. Good news: Put the plug on the front of the box and it's pretty bearable. Towed 90 miles today with it....def louder. Towed ~4,000 lbs and averaged 13.7 MPG......and that was about 35 miles of city driving. Doesn't quite seal to the fender (just bought some rubber weather stripping). ....I'm going to give a few more weeks. Also not sure it's a vibration from the airbox....it could actually be coming from that stupid adaptive exhaust valve...i've already got some clamps to keep it open.

I doubt it, the tube is tapered wider on the filter end. I'll check today though.

Well, the thing sounds awesome wot....nice and deep. Bad---- my wife hates it, son loves it....wife wins. I'll throw it up on Ebay and/or here. I need something quieter. Power wise....nothing high, nothing low.....does feel more responsive at around 2300-3000rpm. Rarely allows the truck to swap to V4...I dunno if that's good or bad. Quieter options?? I will say this filter is HUGE.

Yep, the feet aren't snapping into the stock location holes at the bottom....it's like the "AFE feet" aren't tapered correctly. I've pushed pretty hard on the sucker and it will not "snap" in like stock would. I might go back out and try to force it harder.

Just installed the AFE Stage 2si. Impressions: Build quality- (A- )It's pretty good, there is a gap on the seal to the fender. Intallation- (A ) Pretty Straight forward...I broke one clip on a breather hose before I figured out that all you need to do mash downward. Performance: N/A.....Sounds cool, no difference in the butt dyno, Seems to keep it out of V4 longer...but then holds it longer once it's in MISC: The danged thing vibrates BAD under WOT throttle....I had to make shift shim it to get it to stop. I'll be getting some thick window gasket weather stripping to finalize that part. Other than that...we'll see if there is a difference in mileage. I think it might return some gains w/ a tune perhaps...stock not so much.

Just bought the AFE Stage 2i today for the 5.3L. I'll let you guys know how the install goes. I'm new to the forum, been lurking since I traded in my 2013 F150 Ecoboost (4x4 Offroad, solo mach-x exhaust, 3.55 gears, SSinc tuned, AFE stage 2 intake, and a mild polish on the TB)....on my 2014 Silverado 5.3L CrewCab 4x4. Only mods so far are plastidipped front emblem, muffler delete and new tip. I'm loving the truck...I do miss the 93octane tuned power of the Ecoboost at times though.
