Hey fellas, for those who have removed the Rain/Snow blocker in the grill, I am looking for an honest assessment of the risk for rain getting into the intake.

I have a Rotofab CAI installed, so I would assume it would take a lot to get up to that point.

Though my A10 '20 is not a daily driver, I am in Florida where spontaneous monsoons are prevalent. For the most part, I can control not driving in adverse conditions, but I am concerned for the low chance I get caught up in a storm and rain gets "ram aired" into the intake.

Thanks guys!

GM wouldn't have added the time of development and expense of a part if they didn't think it was necessary. I won't pretend to suggest they spent millions on engineering on a part that costs like $5 to produce, but if, for example, they (and every other manufacturer) skimp on not painting what they don't need to (just look under the hood or chassis for the OEM e-coat where there is neither base coat or clearcoat) to save however much that is on materials, they won't add a part unless it is necessary. I recall reading a part of the book about the 6th Gen where they added a brace to the chassis only on V8 cars (because they needed the extra strength) around the rear torque box. That's one of a couple examples I can argue.

If that part didn't need to be there, they wouldn't add it. I removed mine because I have no intent on driving much in the rain. I would be willing to bet, though, that unless you were under heavy throttle much (and I'm not sure how one could be with this car in the rain), you likely don't have much to worry about. I only have theories though...

Notice any difference (power/throttle response)? Does it block off say 40% of the intake tract area?

I am pretty sure the only real benefit of this is to lower IATs by being able to pull in more air from outside the engine compartment.

I myself have the velossa scoop and I don't think it really does anything besides funneling the relatively cooler ambient air into the intake tract.

Hellcats have a direct hole from the headlight to the airbox. Remove it and don't think about it anymore.

I have a VelossaTech scooping thingy, I've removed the rain/snow blocker and the SC lid damper with no issues.

As another reader posted, you build boost a little faster without the blocker. This gives a bit more punch in the low end. Nothing dramatic but it is noticeable. I also think 6th gear on the standard m6 ZL1 has a little more power likely due to a ram air affect at highway speeds.

I use a 2000 PSI power washer to clean my car. I’ve spayed the front grill dozens of times with a the powerwasher without any issues.

The intake inlet sits pretty much behind the driver side headlight so the airflow path has a slight curve to it.

I suppose if you drive your car directly into the path of category 4 hurricane there’s a chance you might suck in some water. But I wouldn’t be too worried about a typical thunderstorm.

Is this part present in a ZLE too?

I can't say that I did. I did it right after the 2650, between that, and not having driven the car much (I only had the car about 800-miles before adding the 2650; and put those miles on over the course of about 6-months, so I don't drive it regularly enough to really evaluate a smaller change, like that), I couldn't say it was or wasn't worth it. Having, theoretically, more cool air push toward the air box was what I was after. I can tell you, though, moving from the standard RF to their BG was a fairly big difference in flow through the MAF and there was a considerable increase in blower sound. I add those comments because I believe these changes in the intake track can make a difference if you allow the ECM to take advantage of them. Maybe, for the purposes of the deflector, it won't be as big a difference, at least until you're at-speed, but all the little (correct) stuff can add up.

Thanks, but expect a green filter alone makes a significant difference - the stock air filter is thick and restrictive
