Report back on how easy it is when you have actually tried it..
Even some professionals recommend the whole air box be taken out because of the difficulty in getting the tabs back in the slots in the limited space with the box in the car...

I replaced mine and there was no need to remove the entire air box as long as you remove the throttle body air duct by losing the throttle body screw clamp so you can disconnect the throttle body air duct.
Removing this ducting makes it easy to remove and reinstall the airbox/filter cover.

5-10 minutes to take off and 5-10 to put on is simple, is not a big job.
it's not really 10 minutes. More like 25-30.
with my luck the 4 bolts that hold the hood extractor duct on one of the bolts fell, ironically the last one by the passenger side. It dropped and with lots of cursing and sweating profusely in this 92 degree day, I gave up after 5-10 minutes of looking with a flashlight and a magnet.
the pcv lines dont need to be removed although it does get in the way when you're trying to put the intake cover back on.
And speaking of the intake cover. With the new filter, I used bms, it seems that the rubber rim that mates with the intake cover is a lot thicker than stock so you really have to wrestle with it in order for the intake to snap into place again. After that reassembly is very easy and within 2 minutes you're done.
I started the car up and moved it up and down the driveway with no codes or weirdness. But I didn't get a chance to drive it because it was really hot and I was tired, since I did this right after work. So I'll know the results tomorrow.
stock filter looks brand new lol. Kinda wondering why I even did the mod. But well see tomorrow. I only have 10k miles btw.
also does anyone know the part number for the 7mm bolt that holds that hood extractor duct on? I lost that 1 and I'm not about to take everything back apart to find it in the engine bay lol
Remember when changing an air filter was just 1 wingnut and took about 15 seconds? You could do it in the Autozone parking lot and throw your old filter in their trash can. Ahhhh.... the good old days.
Having:
1) removed my OEM 2014 Z51 filter and air duct to install an aFe low restriction system,
2) removed the aFe system when I sold the 2014 C7 and installing the original OEM,
3) removing the OEM system from my Grand Sport and
4) installing the aFe system that was on my 2014 on the Grand Sport- it's easy one you're past the first!
Just unclip that cooling line from where it's attached and it's long enough to pull out the old filter holder and air duct and reinstall whatever. Removing the plastic air duct to the hood vent is the first thing to do but that is only a few bolts.
The aFe filter and filter box is larger than the OEM but it fits very well and is an easy install.
aFe Made in USA Filter left; OEM Grand Sport made in Thailand filter right!
Here is a detailed picture/test of the install. If just replacing the OEM filter some of the early pics show How-To-Do that: http://netwelding.com/Cold_Air_Intake.pdf
Just follow these and you will not have any difficulty getting the filter cover back on and no lubricant needed on the filter seal.

THERE IS NO NEED TO REMOVE THE ENTIRE AIR FILTER BOX!
The key to all this is that everything pops off quite easily, if you are having difficultly in pulling anything apart or putting it back together, your doing something wrong.
1. Remove the hood extractor duct to gain access they are four 7mm bolts, then it just pulls out quite easily. Note: the screws come out so be careful not to drop them.
2. Remove throttle body custom painted throttle cover (no need to remove the holding clamp)
2. Remove the electrical connector (5) from the sensor.
- to remove mass airflow sensor plug, pull up on the RED clip, then squeeze the button and it comes off easily see video if you don't remember)
3. Carefully lift the surge tank coolant hose (1) from both hose retainers (3) and position the hose to be able to remove the screws securing the air cleaner/filter endcap.
4. Loosen the air duct clamp (4) at the air cleaner/filter housing endcap and move the duct out of the way.
5. Next loosen the throttle body screw clamp so you can disconnect the throttle body air duct. Removing this ducting makes it much easier to reinstall the airbox/filter cover.
6. Remove the two screws (2)
1. un-screw with a TORX, the two top screws from the airbox (where the air filter is housed, tilt back and pull out.
2. It may be easier to use a socket wrench with flexible shaft to loosen these screws.
6. Turn the air cleaner/filter endcap downward at the top and disengage the lower endcap mounting tabs from the lower retention hinge features.
7. Inspect or replace the air cleaner/filter.
Care must be taken when putting the air cleaner box back together, the bottom goes in first, tilt it on an angle so the flanges slid into the endcaps, if you do it right, the airbox goes back in place fairly easy, do need force it at all.
1. Reverse Steps to replace the air cleaner/filter endcap.
2. Replace the extractor hood duct. See above.
after reading this thread it makes me wonder if the tech does take the filter out to inspect when having a oil change. Or does he just pencil whip the report based on miles driven
I just replaced the oem with a BMS (Burger Motorsports filter).You do have to remove a few extra pieces on a vette as opposed to most others but if you take your time no problem.

Doubt very much if they "inspect" it as it's much more work than most filters!
That is a side advantage of the aFe low restriction system. Since the filter is larger it needs a new larger filter housing. The housing has a clear plastic window. This is one mounted on my Grand Sport
Did any of you who replaced your stock air filter with a BMS air filter on yourLT1 notice any significant driveability or throttle response improvement, or any other improvement of any kind?

Just installed the BMS filter on my 17 Z06 and upon startup i see "the engine will operate with reduced power" I know this is an issue that others have dealt with and now I guess more research to go for me!!
FWIW, reduced restriction air intake systems can cause an LT4 engine to run lean. I found that the GM sold low restriction system has only half the flow improvement of the aFe system, which like mine, is a significantly larger filter. Not an issue with the LT1 but folks have reported ~40 hp increase with the LT-4 and some low restriction products. That may put in outside the OEM air/fuel MAPS so it can't adjust properly. Like installing headers a "tune" may be needed.
