I ripped mine off the other week. They're not needed and if you've damaged them they cost about £100 for the centre and £25 for each side part.

I got mine replaced.

Personally I'd replace it, had many a speed bump scrape it so without it you might damage something

This has been covered lots of times, but the tray apprantly helps with airflow and cooling etc etc.. mine got damaged ages ago, and its a pain to remove to change oil and things so mines never gone back on.. never had any problems by not having it... You will get a bit more crap flung in your engine bay though..

Mine was broken off when I bought it a month ago- the sides are still there just not the bottom. Been told by 3 mechanics that it basically doesnt make a difference, just makes the engine a bit dirtier by it not being there. So I am definitely not paying to replace it when it is only likely to fall off again- unless someone told me a good reason why I should

The LCR undertray is long and has ductwork to direct air where it's needed in the engine bay. Other petrol undertrays are comparitively short. Diesels have a longer tray fixed on all four sides, with sound-deadening treatment.

All undertrays smooth the flow of air under the car and help the airflow through the radiator, assisting a little with stability at high speeds. They keep the underside of the engine clean and stop stones and so on getting up into the pipework. I'd replace mine if I lost it.
