Title: Carbon Fibre vs. Plastic airbox..
Post by: jamie_pyrite on 14 March 2009, 15:26
So I was in my mate's car today. His friend phoned him up and they chatted via the car's bluetooth handsfree so I could hear the conversation. The lad reckoned it's worth paying £200 for a Carbon Fibre airbox on  a 75bhp Saxo!  :grin: He reckons that because it's made of Carbon Fibre rather than plastic, it makes a massive difference in performance between the two.. Something to do with "heat soak" he said!

Just me or does this sound like a load of rubbish, considering all the airbox does is passes air through it! As long as they are the same dimensions and smoothness inside, I wouldn't have thought it'd make a difference?

well technically he was right. A carbon airbox like the BMC induction kit does keep the heat out. Engines perform much better with cold air rather than hot air. Now, spending £200 on a BMC filter or similar on a 75hp saxo is just plain stupid, cos there will be so little difference its unreal.

All true. With 75 ponies on tap he will need all the help he can get.

He's right about the heat soak, as kharekatoh explained. But on a 75hp engine there's no point at all really.

Given the speed at which the air is hosing through the airbox, can anyone honestly kid themselves that a carbon fibre airbox is going to improve anything other than the cosmetics of the vehicle?

It's going to functionally improve neither the Saxo, or a Golf5 GTI, if the shape of the airbox is the same.

If there is an improvement to the shape and functionality of the airbox/cone filter then maybe it's worth another ~5bhp but manufacturers tend not to fit rubbish intake systems to their cars - why would they?

The carbon speed / carbonion intakes for the 2.0T are good :)
