HI PPL, I Have just de-restricted my air box and fitted a K&N panel filter, ppl have fitted a vectra induct to re-place the astra-g one but i was thinking of getting a big hose (about quadruple the volume size of the vectra intake) to go from the air box straight to the front bumper.
I have been told from a friend of a friend of a friend that this is not a good idea as it will mess with the air mass sensor thingy as vauxhall ones are pretty sensitive and i won't get a correct mixture of air and petrol (will get too much air) and will end up with having poor performance than standard, and have a dodgy running engine even when put back to standard.
Is this true??? if so are their any other options to the vectra intake (apart from the pipercross hose)
Also haven't noticed any difference in accelaration or top speed or general smooth running from de-restricting my air box and having a K&N panel filter could this be because a lack of air getting through???
sorry for the detailed story but anybodys opnion or advice would be helpful, cheers
