i have noticed that the air box lower half as been drilled with about 30, 10 mm holes anyone know if this is harmfull and why it might have been done only just noticed it.

 

I guess someone did it to let more air into the box.

 

well yes but why i wonder standard work fine dont they .any one else done this i only mention it as i have had some idel problems ....

 

I would expect they did it because of poor info or something they read on the internet etc.

Normal causes of dodgy idle are an air leak,dodgy VTA,MAF or coolant temp sensor (normally only when cold though)

 

cheers fella thats why im askin really i have purchased a coolant sensor to fit and just wondererd if the extra holes takin in more air could have affected maf im just tryin elimination thanks for your imput ..

and yes its only from cold ...

 

toigye, just get yourself a cheap replacement off eBay...

 

yeah will sort it mate just thought id ask the question some clever guys on here

also some ones lol .....cheers pal

 

used to see it done back in the day on old 3i's and that
gave a bit of an induction roar , and dependin on where the airbox was i suppose it would allow a bit more air flow
BUT never would on a scooby , would draw nothing but warm air anyway

 

yeah i would agree with that point well made thanks

 

thats ok

 

ive got a few mates who have drilled their air boxes. it makes the car sound a bit louder and give it more of a rumble. but ive only heard of boy racers doing it to make their cars sound like subaru's.

 

its done by idiots thinking it lets more air in but it just lets heat in so it sap's performance and uses ya fuel quicker
