Underbonnet sound insulation

[El Dingo]

Anyone fitted this to a petrol Octavia?

Did it make any difference?

[RGKTSi]

Yes I did, when we first got the car. Not made any difference that I could tell.

The only reason I went for it, help keep the temperature up during freezing whether

and to stop the underside of the bonnet getting dirty.

[DGW]

How easy is it to fit and what did it cost, please?

[RGKTSi]

I believe from memory it was about £20, not expensive.

To fit is dead easy, literally a 5 min job. A number of clips

around the edge that you line up with the holes on the underside of the bonnet

and just press them in. It does finish the underside of the bonnett off nicely.

Thankyou. I will put one on my list of 'goodies' to buy.

The 1.8TSI is so quiet I'm not sure it would make any difference. I came to it from a 1.9PD so that may colour my judgement but the engine is already drowned out by the road noise.

[Evening Star]

Fitted to my 1,8 TSi, and it helps keep the noise down & helps the engine warm up quicker in cold weather, worth the £22 that I paid for it and it's dead easy to fit.

What Picard said.... surely not .

Have you try turning the radio off and ventilation off, all you heard is road noise and a very faint engine noise untill you push pass 4000rpm even then the engine tone is nice and not hard on the hears

[Evening Star]

On the hears?

My must get my heyes checked...

[ramonford]

Endorse all the above plus when you lift the lid it makes the engine bay well finished rather then some thing that's been forgotten.

Its the first thing most people will notice when its not there.

Also when you drop the bonnet down is doesn't sound like like an old tin can, but some thing more sophisticated and precision built.

Well worth going for in my opinion

Does it come with the clips?

[RGKTSi]

Yes it does.

[CEPi]

Here is mine. Didn't fit it for the noise reduction as I have a full sport exhaust, but just so the underbonnet doesn't look naked and empty like a 1980's cheap car.

Clips have a different part number, so if you are doing a DIY order make sure you order both.

[El Dingo]

Brilliant and useful answers, thank you.

I especially agree that the car seems 'unfinished' without this, and a little bit more refinement wouldn't go amiss.

I'm off to buy mine next week - the price seems reasonable.

[blueR36]

Cost cutting, mine came with it as standard, and my friends car really does sound tinny when you drop the bonnet,,and as above does look unfinished

[dainott]

Yea think i will invest in one of these and cant understand why it isnt fitted as standard!

[Evening Star]

It does make a difference on how quickly the engine warms up in cold weather.

Does anyone have the clip # and Qty. please?

[Evening Star]

I just ordered the thing at the dealership & asked for the securing clips as well and they ordered it and the clips came in a bag, I think they supplied about 20-24 of them.

My local dealer said they didn't recommend fitting the insulation mat on petrol models, due to the higher heat development in petrol engines... I'm not sure I'm buying that explanation. All my previous cars (Vauxhall, Nissan, Honda - all petrol models) did have an insulation mat fitted. Cooling seems very good on the Octavia as well, the grill / airflow to the radiator area is quite huge compared to some other cars - at least my latest car - the Honda Civic with the whole front covered with plexiglass...!

It's guff. They used to fit the pad as part of the standard build. It's just them cutting costs.
