AutoQuest Motorsports - 981 GT4 Side Intake Screens
The Issue
The GT4’s side intake ducts have recessed vents that are difficult to see and clean. If not routinely checked, they accumulate large sized rubber/debris blocking the vents. These vents also have relatively large openings that allow a good deal of the smaller rubber/debris to bypass the vents and make their way up the intake to the filters. Both these issues can lead to a significant reduction in airflow over time, reducing the car’s performance.

Our Intake Screens are installed at the entrance of the intake ducts, providing an immediate and significant reduction in the amount of rubber/debris in the intake system clogging the vents and dirtying the filters. Being at the entrance, they are also more convenient to check and clean. This is a great upgrade to the intake system for the street, and very beneficial for those tracking their cars. It also looks fantastic : ).

I haven't yet created the PDF install guide, but it is a relatively quick job. Once the car is in the air the rear wheels come off, followed by the inner fender cover. Then there are a few screws to undo that allow the side panel to move enough to slide them in place from the rear. Pretty painless : )

Expanded Aluminum mesh?

Indeed, also form fit to the intake opening
I'll be doing some photo/video documentation on our next installation. That being said, I happened to have a Spyder on the lift yesterday and took a little video explanation for speedy974 with my cellphone of how the install goes. I'll shoot you a PM, perhaps I can email or text that over to you as well.

I cleaned air filters this morning. I could not believe how hard it was to pull them out. I don't have that puller tool I've seen on rennlist, but have a wrench that fits perfectly into the tabs on top and bottom which makes sort of a handle. I actually broke one of the tabs. Ended up having to pry around the edges, pull like heck, and throw some 4-letter words at it. I was thinking someone glued them in as a joke or something. It was cold, so maybe that was the issue. Never been that hard before...
To the point of this thread, I found a pine cone, a lug bolt, about $0.85 in change, and a happy meal toy in the airway.

Is there any data or testing to quantify the reduction of airflow into intakes with screens installed?
My understanding is the airflow is engineered to a specific volume. Would the screens inhibit enough air to be a long term issue (cumulative effects over time)?
I realize debris also inhibits air flow but it can be regularly checked and removed. The screens are there all the time.
They look great and I’m inclined to think they are beneficial.
My conversation about the airflow was with someone I trust who is extremely knowledgeable and technically savvy in the world of Porsche performance.

To answer this question yes intake screens do logically inhibit airflow, as they do when installed by Porsche as factory equipment on the GT3s. We haven't seen or felt any decreased performance or lap times on track with the intake screens installed, but we certainly have on cars with their intakes/filters clogged full of rubber and various other debris. That being said, these exact screens are being used consistently in Europe on GT4s by race teams such as Manthey-Racing. We have experienced what they have experienced, which is significant blockage of the air intake system by debris not just at the ducting entryway, but all the way up the air ducting and covering/saturating the air filters, and unfortunately a complete intake system cleaning and replacement of the filters is time consuming and necessary to do often, even just to check what you can't see. It happens quickly enough and significantly enough under race conditions and track days (especially in two/four wheel off scenarios and running off line) that it has been a no-brainer to install the screens for more consistent airflow and prolonged intake maintenance intervals.

It was great chatting with you today as always : )
