Check your Air Intake Hose Clamp

Several of us in the MAF clean thread have reported that at least one hose clamp on the air intake box is significantly loose from the factory. For me, the one you can see with the plastic engine cover closed was not even hand tight, in addition to several other members. The second clamp under the plastic cover was about a half turn looser than what I'd consider tight. Build date of the truck seems to be irrelevant.

As this interface is downstream of the MAF, its possible that air flow is allowed to bypass the filter, and may result in sluggish throttle response or inconsistent/decreased fuel economy.

Please use this thread to post your findings, and any impact it's made on driveability.

 

Glad to see this thread, my 2017 manufactured in 02/17 had this clamp very loose!

 

Just like the electrical wiring tape coming loose on my truck within the first 15k miles

 

This is a very very good callout - the clamp on mine when I cleaned my MAF was also loose. It wasn't even hand tightened.. and took several twists to get it tight enough for my liking. Throttle response has been much better since both the leaning of the MAF and tightening of the clamp.

Hasn't resolved all of my issues by any means (MISFIRE city...) but definitely addressed some high MAF readings and significant bogging I was experiencing before.

 

Born 4/2017, just went and tightened mine down. Clamp was pretty loose, not coming off loose, but it sure wasnt tight.

 

Where else would you check for potential intake leaks? I'm pretty sure my intake is operating as expected following my MAF clean and clamp tighten but damn I can't really trust that anything was torqued or assembled properly. Sad, but true

 

grab a bottle of starter fluid and spray around---any leaks will cause RPMs to spike.

 

Holy crap, checked mine but 02/17 spun it with my finger tips. Wow

 

Hey, thanx OP.... I just checked my 09/15 born on date.... and the clamp in question was not "real" loose , but it took a full turn or so of the 1/4" ratchet....... Loose enough, in MY opinion to allow extra air in there...

 

Just checked my 10/16 born on date and it checked out to be good and tight.
There ya go.

Initial Quality Scores are LOW... and we wonder why.

 

Born on date 1/17 Texas. On tight

 

9/15 Baja
Tight.

 

2/17 Texas
Both clamps tight.

 

1/17 Mex both tight

 

Good thread mateo, loose clamps can cause driveablity issues for some, my build is 2/16 and clamp is tighter than a crab's ass!

Cheers!

 

Ok... Is the Crab's ass tighter than a frog....????

 

Where is the other clamp you guys are referring to? I only checked the one pictured.

 

Just that metal clamp on the intake hose right?

Mine was as tight as could be. If I turned it any more I might start breaking stuff.

Mine looks to have a notch that makes it sit in place differently than the ops pic. Do you guys have that? It's on the opposite side of the hose from the maf.

 

Mine does have a little locating tab on the side towards the front of the truck. You can see his towards the bottom of the clamp.
