Has anybody installed one of these yet?  I saw a review by Lonestar Hawaiian earlier today and I like the concept, but I'm concerned about quality due to the plastic being different from OEM.  I'd hate for it to be too hard and crack while driving down the road.

I highly doubt it's going to crack. From what I could tell it looks more like ABS plastic than whatever the factory is using. This is on my want to buy list after seeing his video of it the other day. I didn't know it had been out for almost 2 years already. Stillen's website seems to be the only place to buy it.

I contacted a YouTube content creator I know in Southern California.  He knows a few guys with Trail Bosses (my truck has been in a couple videos).  He said another guy he knows has this on his truck and it caused issues with the active aero shutters in the front grille.  He had to take a dremel to the Stillen piece to trim it back and eliminate the issue.  That's not something I'm interested in doing until I've seen the modified setup.  I almost pulled the trigger on this today, but decided to take a step back.

The guy in the video says the factory scoop has hot air coming from the radiator through the vent and into the intake and  theirs stops that now my question is how is hot air going to come up through the factory scoop/shield when the truck is in motion and air is blowing though the radiator and grill? I think its just another thing for the company to make money on that doesn't work.

I would be worried driving in a heavy rain following a vehicle that is putting off a lot of spray and getting sucked into the intake.

The air comes from the radiator side of the shutters. If the shutters are open you get cooler air. If they are shut you get warmer air.

Iirc, the shutters close at 55 mph, right?  So, if the shutters are closed how would the Stillen scoop work?  It doesn't sound like it would.

      Do you remember that Harley Davidson was more successful (solvent) when it produced about 60% of the market demand (by design) and forced wait times of up to three years? Even when your turn came around it was, "Take what we are giving you or move to the back of the line and start over". HUGE markup's were 'normalized' and dealer killed. 40% markup and no floor plan? What's not to love? Greed will kill them yet. They have surplus production and customer base is tanking. And still they think nosebleed pricing will work.

      The engine was done as part of the 6.2 recall?   You'd have to see if your VIN also has the 6.2 engine special coverage on it.  Coverage number is N252494003.  If you have this, your engine is covered under this and NOT the GM replacement part engine warranty which is 3yr/100k from the date of install.  The 3yr/100k mi warranty is in effect for non warranty purchases.     This is not any different if it was replaced under warranty without a recall or special coverage.  So if you had a 5.3 and it popped at 3 years in at 50,000mi during the 5yr/60k powertrain, the replacement engine would not get the 3yr/100k, and instead gets the remainder of the 5yr/60k as coverage.     So N252494003 gives 10 years or 150,000mi of coverage, which ever comes first, starting at the vehicle in service date.  So if your in service date is 01/01/2022, N252494003 gives you special coverage of the engine until 01/01/2032 or 150,000mi, whichever comes first.  So if your start date was 01/01/2022, you'd have left 5 years and 4 months (lets round to august 1st), or 62,000mi left of coverage.   So you need to know your in service date to know how much coverage is left.

      Injector update

      By CamGTP · Posted

      Okiee dokie there bud, way to take things to the extreme.   I guess you missed the whole point and take things way to serious. I installed different EV6 style injectors that just so happen to be larger in my car running the same LQ4 engine and with a better spray pattern than the stock style injectors and I noticed no difference in the idle quality. Kinda was my round about way of saying that even if you put the same size but better style injectors in your truck, you will likely see the same thing.    I'm sure you're great to have conversations with in person if that's how you act through a keyboard. One little things sets you off and now I guess my dick is all up in your face.

      I can't believe that could possibly be the case. It should be 36mo/100k miles from installation. Then again, it also seems like since a dealership installed it, it'd all be in the system and you wouldn't need to worry about registering, either. Shows you what I know. 😄 Hope this one outlives the warranty!
