I have Zunsport grills on the front of my base Cayman and at the track in June my driver-side grill had two huge cicadas smashed on them. I knocked them off after a 25 minute run and saw no increase in temperature during those laps. Maybe the other side compensated, I don't know. Normally, no negative effects from the grills.

On my 18’ 718 CGTS, I used Zunsport in the front and RGS on the side vent. Car was on the track and both performed as intended (can tell how much rubber string did I pulled out of the side vent grills)
I think the Zunsport look cleaner in the front.
But at the end pick the ones you like most but put something for your own sakes.

Had front and rear RGS on our BS. Both side vent grills slipped down slightly, leaving ~1/4" without coverage at the top. No real worries about anything getting through; however, I didn't like the way they looked once they slipped. I prefer the RGS side vent look, yet currently leaning toward either Zunsport or Rennline for the GTS.

First dealer I took my car to for sale assessment immediately saw zip ties and asked what happened. Gave him the story and he said those would have to go. Interesting he picked up on them with not much inspection. I thought they were inconspicuous, but I guess not. It never bother me in ownership and I preferred the "behind-the-grill" look. Either will do the intended job.

Kind of ironic Porsche puts the grills on the GT cars which are expected to track. Next thing we'll see them as options for a good bit more than the usual offerings lol

For those that may want to make their own custom grills, this place offers some interesting grill patterns. They don't have ready made grills for the 718, but I like how they have done them for other variants. Interesting they use a neoprene trim around their grills. I may make my own for the 911. I don't think I'd like the Zunsport grills for this and not sure I like using zip ties for this application via the RSGs. Rennline makes them for the 991.1 GTS, but if I have to remove the bumper cover to install, I may as well make my own and save a few hundred. Kind of ridiculous what these companies charge for these considering what they are and what they're made of. Heck I just remembered I have a full sheet of the same anodized stuff the RGS uses, down in my wood shop. I may use that or I quite like this grill pattern. I think it's very much like the GT3 grill pattern.

Bought the RGS grilles for the front of my BS. Like the grille appearance but hate the cheap tiewrap look. Like others mentioned, they seem flimsy. Depending on hand size, they can be hard to install without proper tools. I have clubs for hands so you might imagine how it went for me.

Bought Zunsport grilles for the side intakes. Easy install and very high quality. No cheap tiewraps! I can understand why some might not like the look but I didn't really mind it.

Checking on returning the RGS for Zunsport as we speak.

Update: I was able to return RGS front grilles only having to pay return shipping. RGS support was very professional in all aspects of purchase/process/return. Great company!

I replaced with Zunsport and I'm very pleased with final result.

Did mine today. I have a YouTube channel that I started for DIYs in my Macan, and now extending it to the Cayman. Hence, video of my installation experience here:

I missed this thread. I installed RGS on my BS about 4 weeks ago. I bit of a fiddle both half hour to do both sides including masking up. A Gynaecologist could probably do it in 15 mins tops
I prefer the OEM grill look of the RGS to the Zunsport and in blighty they cost a third of the Zunsport grills

I noticed that some of these are mounted in front of the louvers and some are mounted behind them. How do you get them behind?

for models with the Sport Design - (GTS and GT4 have this as standard) - they don't have the horizontal slats

so the Zunsports don't cover up any grille slats (with Sport Design front)- for the other models (Base / S) many prefer the RGS which install from behind w/ zip ties for more of an "OEM" look with the slats exposed

There is a PCGB discount code that gets you 20% off. Personally for a Base or S I prefer the RGS grilles. For the GTS or cars fitted with the sport design package, the Zunsport grilles look better.

I ordered mine for my 2018 718B and was stumped immediately when my Black Package spoiler prevented access from underneath the lip. Instead of securing from the sides, I used the support arms below the lip to attach two zip ties per grille and it’s holding perfectly. Overall, 10 minutes to install and a great value for protection!

This Forum is a wonderful resource!!
I've found out about the RGS intake grills and contacted them: lightning response to let me know that Design911.com has them in their UK warehouse.
All I need to do is order them!

 

[scratt]

I used your video guide today @santirx. Thanks!
RGS grills were very easy to install. Of course in Iceland I could not find a hook tool, but improvised with some net curtain wire with an open hook in one end. That made pulling the grills into position super easy.
I also evened up the cable tie look by adding a middle one on each side of each grill. 😅
I plan to use the complimentary beer holder that came with them to toast a successful install later this evening!

RGS reached out to me, and asked for my installation video. My video is the one showing up in their website as installation instructions for 718…😁

Great video, Santirx, keep them coming.

For anyone having difficulty finding the essential hook tool, they're sold as O-ring removal or pick tools. Mine was in a set with pointy right-angle tips similar to a machinist's scribe set, useful for popping small electric connectors like the clear side marker lights.

Thank you for the video! Fortunately had the tools as part of a kit I received from a company that sells speaker equipment for BMWs (my other two cars). Went great!

 

[ICE718]

Today I fitted my radiator grills from the Radiator Grill Store based in the US (www.radiatorgrillstore.com).

I tried the Zunsport grills and didn't like the way they looked. These look more OEM and are really easy to fit. Took me all of 10 mins. Not expensive either but shipping to the UK is more expensive than the grills themselves yet the total cost is half that of the Zunsport grills shipped in the UK.

Overall, very impressed and would highly recommend.

Do you know if this is better/easier to put on before or after PPF? I would think after but not sure so any deatliers on this forum! lol

 

[Porhaus]

Not easier nor harder with PPF in place. You'll want to use painter's tape (or similar masking tape) regardless of whether PPF is in place because the grills do have some rough edges.

Got my RGS grille (front and side vents) mounted today. My impression

Front Grille
1. Front passenger/driver side grilles were not too hard to do. The YouTube video from RGS was very helpful, although make sure you don't just jam the grille in place without having your hand between the grille and the radiator to make sure it doesn't poke at your radiator. The zip tie is barely noticeable

2. The front center grille was a bit of the pain in the ass. You have to gently bend the grille to fit it and then have to methodically use a pick tool too pull the hexagons (one row at a time) toward you to re-align it. It looks great afterward but was very time-consuming.

NOTE: If you don't have one of those pick tool, go get one at your local store, amazon or other site. I got a set of 6 (fairly heavy duty) for less than $8.00. You really cannot do the job without it, especially the centre grille.
NOTE: Before you install your grille, run your hand (with gloves) along the edges. Mine has several wires that pointed out at 90 degree angle . I had to use a pair of pliers to pin it flat


Side Vent
1. For me, I had PPF wrapped and my guess was that the PPF tech didn't mount the vent back properly. I was ready with my car trim removal toolset but when I used my hand to test pull at the vent, both of them popped out without much force . I guess I am lucky that they didn't fall out by themselves on the road somewhere. But this saved me a bit of time.

2. The side vent grilles have the same quality as the front grilles including a few wires pointed in the wrong direction. However, the fit was quite poor. If you look a this RGS install video at 3:26 mark, the tech just popped it in. For mine, I had to bend around the edges to make it fit properly. It wasn't super difficult but definitely not the same experience as the video.

Overall, I am super happy with the look. I was deciding between RGS vs Zunsport. Even though Zunsport is cheaper with the 20% coupon, I think the RGS looks way better.

Got my RGS grille (front and side vents) mounted today.

One more additional note. Ten zip ties (8") come with the package so you do not have to go out and get them. Getting the zip tie into the grille and looping it back out with the "least" amount of hexagons in between was very painful. I wanted to have the minimal hexagons in between so that the result looks neater. After spending 20-25 minutes trying to work it (lots of swearing in between) , I almost gave up but then I thought of a trick.

It's a simple 5 step process using the concept of threading the needle. It's best explained with a series of photos. See attached.

Hopefully this will help others.
