Hi all!

Picked up my MK8 PE last week, only has 10k miles on it which is the newest car I have ever owned!
I noticed that the, I suppose fins behind the grills have small bits of debris, some tiny stones lodged in there that have bent some of the fins.

I was wondering had anyone any cheap solutions or DIY ones to fit a mesh behind it to protect this? I know Zunsport do one but at the price it seems a bit dear!

Any help is appreciated, thanks!

If you mean the radiator fins then I too would welcome some advice how to gently get bugs out of them. I really don't want to start poking about with a brush or jet blasting as those fins are quite delicate.

I figure its down to the amount of cooling the engine needs but this car collects bugs like now other I've had.

The big hexagonal grille holes just let our winged friends stream in. I've got 'bug on bug' action in some places, not in a sexy time way either! Dead bugs under dead bugs, under dead bugs. The build up must reduce airflow.

As regards fitting a mesh @JamesC115 I'll let the more experienced owners give you a definitive answer. But my amateur two penneth worth would be the car needs a strong flow of cooling air. A mesh would interrupt the flow of air and risk it running hot?

Yeah. I think it seems like using a damn pair of tweezers is the best bet!

You are very correct re the air flow in. I was just curious since I saw Zunsport retailing one. Though that's a bit different to me buying some thin stiff mesh and doing it myself....

Just looked at the Zunsport products and they look good. Would the intake of air really be that inhibited but these grills, as @Keithsson stated, over to the experts on the forum. I did think to amount of opening through to the radiators looks excessive. What isn't very clear is how you would install these behind the existing grills. I have watched a video on Youtube and when installed over the top of the existing grills I think they look terrible...😎

That sounds like it wouldn't be covered under warranty🧐
SSSHHHHH 😲

Very true, luckily a good friend of mine is the lead tech and a fully qualified mechanic, MOT chap and all round Ford nut at the main dealer I'll be using for servicing and any other issues. He has confirmed that a warranty claim for any thing other than the things I have changed will be good. The only thing it would fail a claim on is remaps, so potentially may either not remap until out of or nearly out of warranty or take the chance, I know Superchips Bluefin have their own warranty for their maps if found to be the cause of any engine damage, there is always options.

@Twiddle, I think you can get arrested for Full Frontal Intercoolers🤣

I’ve had Zunsport grills fitted for protection. They are well made and I know opinions of how they looks are subjective, but I like them.

Zunsport upper and lower grilles fitted here too and my Mountune Intercooler hasn’t got a mark on it….I bought these grilles with the intention of protecting the intercooler from picking up chips or fin damage and they’re definitely doing their job so far!

Hi @old dave, I can see the benefit of these grills, but I would have them fitted behind the stock grills probably costing more to achieve this. I wonder if you have had any engine temperature issues, particularly during the really hot weather recently. I don't personally like the look of them fitted externally, but if we were all the same the world would be a boring place. Beauty is in the eye of the beholder and personal preference must always be respected👍🏻

No engine temperature issues at all after fitting the grills.

I'm assuming the screws that hold these in cause some pretty nasty holes in the original upper and lower grills? I'm thinking of getting just the lower one but not sure I want to damage the bodywork screwing this in :(

I always soften them first with a bug squash remover, that's the key. Then you can remove them with a gently hose. Ideally from behind, or more realistically from a higher point, so the bodies don't get driven into the fins.
Wire mesh grilles like the Zunsport won't affect airflow in any measurable way in this application.
I'd personally be more concerned about higher intercoolers affecting airflow to the cooling radiator to be honest, which is something I've thought a fair bit about. It's not just the affect on the airstream, but temperatures. The radiators are designed for a specific range of temperatures in and out. So the air passing through the intercooler leaves at a higher temp than it enters (obviously) and that hot air will then go to the cooling radiator if the intercooler is in front of it. So the radiator sees a higher temperature than it would otherwise. May not be a problem most of the time, but it will have an effect during hot weather, when your intercooler is working hardest and so is your engine cooling. So if/when I fit an upgraded intercooler I'd personally be looking at a design that was the same height as the stock unit.

Re bugs in the rad - power washer at an angle and make sure you have waterproofs on. You will get soaked but be bug free.
soft/medium setting.
And wear safety glasses as I had to go to use an eye bath kit after I first did it.
Re the full size intercooler should be safe up in Scotland never gets that hot 😂😂😂
