The Airbox Mod That Nobody Does

[jaxouk]

HI ALL, i have done the air box mod (long time ago) but reading through the posts i have saw that you can mod the top of the airbox too. there is a pipe that comes into the top of it (just beside the air meter) and i`ve read that this can be cut away to make the airbox mod even better. However i have also read on here that this is potentially dangerours to the air flow meter and shouldn`t be done......but saying that people have also said that the vxr has this mod done as standard so there is a lot of conflicting info. basically what i want to know is has anybody done this? and if so has it caused any damage and lastly does anybody know if indeed the vxr has this as standard or am i going to be the first to say "ffs this wrecked my airflow meter" LOL

cheers in advance!!

I did it on my old 52 plate astra coupe and never had any problems.

yeah same as mate i had a y reg sri astra (1.8) and done the airbox mod (both parts) without any problems....i must say the difference between the airbox mod in the astra and vec was huge. tbh the mod in the vectra was hardly noticable, so its got me thinking maybe the top bit needs to come out to as, if you want more air into the airbox you need to get more air OUT as well and the top pipe is restricting it. have read on here not to do this tho..

COOL!!, cheers mate these are the results im looking to here. been tempted to do mine for a while now....just scared of messing things up cos ive been told the airflow meter is over £200. did you just cut the top pipe out? what did you use for doing this? hacksaw blade with tape around 1 end?

Isn't it clipped in?

no mate the one at the bottom just clips out, but as far as i can see the one at the top would need to be cut....correct me if im wrong tho

Ok I was wrong, was sure my astra one was clipped in and i assumed this was the same

CHEERS! i think i might give this a go, just waiting on my ebay k&n to arrive. might get the gsi intake too and do all three together to see 1 big improvement instead of three little ones!
