Hi All,

Today whilst driving down the M1, I heard something scrape really bad and upon investigation realized it was the tranny splash guard hanging loose.

I also realized I dont have an engine splash guard (I thought I did). Probably why it came loose over time (screws and spire clips hanging out).

I have zip tied the tranny guard down quite well but my question is....

Is it worth having an engine splash guard, it obviously hasnt had one for a while, so I am not sure what to think?

Any input would be great

Cheers

Yes it is worth it IMO.

Firstly, it stops road shit getting thrown up all over the engine and into the engine bay in general.

It also keeps engine noise slightly more muted.

Also, when it's really wet, there is a risk of the front pulleys getting wet and belts slipping (which is the reason the guards were put there in the first place).

Hmmm I see what you are saying, How much do these cost? I suppose second hand is the way to go here.

I will probably source one used and have it ready for the service it is due in May where Ill get the dealer to reinstall it for free as they would have had to take it off normally in the first place.

Cheers for the input

No idea.

Although plain black plastic trims/ducts/etc I've found not to be too insanely priced from BMW

For my E90 335i it was £96 from BMW

I've been looking for a second hand one for ages but have been unsuccessful so far.

Yea it seems there isnt any available but £96 isnt bad i suppose. Still though seen as its going to get dirty/cracked quickly I would rather pay little money for it.

I am in no rush so Ill see if I come by one in the next few months

Thanks for the input!

it is worth the money, when it is properly mounted it will protect the engine as well as keep the airflow correct for cooling and aerodynamics.

The protection of the oil pan is a reason alone for me. In the long run if you drive highway a lot the fuel savings will pay for the shield.

Really, so your saying that mpg increase is noticeable?? By how much % would you say, 10%?

Strange as when the car was in the air I noticed something straight away - Lets see if you spot the issue





I think something is missing from here

I am trying to find a part number and I think its this 51757059387

Which is this -

Large rats or stupid careless last owner - I'll leave that up to you

Waiting on a bmw price as that ebay one looking at feedback isnt the best fit ment

The main reason for the flat floor is MPG, not to stop the belts getting wet, or offer any sort of protection.

I suspected this, I am sure anything that has enough momentum to damage underside parts would probably break through the under shield anyway. I get cooler temps this way lol and if I drop anything whilst working on the car, I can easily retrieve it

[Digitalize]

It would protect against scrapes, but you'd be scraping for a long time before any damage was done anyway. Hard knocks will pass right through.

I imagine it also helps with the NVH factor too, smooth air is less noisy.

That eBay link says no to the fitment of 335i on the listing.

Cotswold the forum dealer with discount quoted £144.37 (part number 51757059387)

Reading reviews on the ebay item fitment isnt that good so looks like a OEM part really
