I saw these on Suncoast. How much debris actually goes in our side vents? I would image not very much vs. the front bumper.

My MY'17 doesn't have them. These were introduced as a standard part some time in 2018. I suspect they will be standard for MY'19 models as well. There was at least one case of a early 718 catching fire due to a cigarette sucked into a side intake. Might be the reason why Porsche came up with this part...

...looks like a good idea. Especially now that it is offered as standard. Never heard that story...hmmm...always thought smoking was a nasty habit anyway...sorry guys, when your butts take out a 718 or the like, ZERO "TOLERANCE" here!?

I think I may consider buying these. After reading this thread, I was washing my car and decided to inspect the intakes. I put my hand inside the left intake to have a feel around and pulled out a very small stone/ pebble.
Hopefully they will have protection for the front intakes (GTS).

Just ordered and installed. Less than ten seconds each - like snapping a lid on a jar. I think they make sense; the openings appear to be a point of vulnerability. The price is highway robbery; I think these should have been part of a recall / free distribution.

I just checked my CGTS from April/May build. It does not have them.

Try shipping to the UK, around $100.

I looked in both intakes on my GTS and nothing on the passenger side, but the drivers side had three small pebbles. This gave me a thought. I looked at the picture of the snap in grills and the openings would have still let these small pebbles get through, plus looking at the design, the tabs that lock them in place are on the backside of the grills. I would imagine that once in place they will be a bit of a pita to remove them to get out whatever small stuff gets past them. I have a handheld battery Dyson vac in the garage and it has an extendable crevice tool that reaches in there quite nicely to remove any leaves or other detritus that may make its way inside.
I could imagine areas that have cottonwoods and the spring seed blizzard that occurs in some areas could really get the radiators pretty clogged, and the protective grills will do nothing to stop those little cottony fluffs. I have to clean my a/c condensers on two units every spring and they get pretty clogged up. I'm going to leave mine open so I can vacuum the surface of the radiators as needed.

Respectfully disagree with Wriggly - just because you found a couple of pebbles smaller than the grill openings doesn't mean that they would have gotten in anyway - good chance they would have hit the slats and not the small openings straight on. My purpose in putting these on was to avoid catastrophic intake of something larger, especially on the track. There has to be a reason Porsche is making them standard in 2019.

I have 7000+ miles on my 2017 Boxster. I live in the mountains and so face some road gravel on occasion. I have some small dents in the passenger side ICAC radiator. It's pretty much impossible to comb the fins (I tried). The cost to replace someday has to be crazy large, even if for just labor alone. Sooo, I ordered the grilles last night after reading this thread. IMHO, I figure any deflection is a good thing.

Speaking of the "Low-temperature modules with electric fan and ram-air flaps" as Porsche calls the side intake radiators of the separate, dedicated low-temp cooling system for the Indirect Charge-Air Cooler (aka Liquid Intercooler):
Lovely color exploded illustrations of the charge-air cooling system on pp. 36-37 of the Porsche Service Tech publication https://www.ebsracing.com/files/2017 718 boxster intro lr.pdf
I think they are the nicest visuals in the the entire document, which has a lot. And they have impressed upon me just how sophisticated is this secondary cooling system, new and unique to the 718. It makes me wonder if more efficient liquid charge-air cooling (versus the simple air-to-air on other Porsche turbos), resulting in a cooler denser cylinder charge, allows 9A2B4 to generate more power with lower boost levels. The alternative possibility is that the mid-engine design couldn't flow sufficient outside air over a conventional air-to-air IC, but it seems that could have been overcome with fans and ducting with less cost/complexity.
