    well no is the shortest answer :P a cone filter will jsut soak up alot of heat....
    best option will be to do the airbox mod.

    if you want something with some noise that an enclosed induction kit would be best, like a viper or venom

    I might as well resurrect this thread as I have questions relating to the same subject and car.

    So is it widely accepted that a cone filter without the shielding would have an adverse affect on the peformance?

    Can anyone recommend a good budget enclosed induction kit and where to get it from?

    Thanks

    well even with shielding it can still soak up heat, for example these two set up.

    and
    http://i151.photobucket.com/albums/s...y/IMG_4220.jpg
    http://s151.photobucket.com/albums/s...t=IMG_4221.jpg

    both were mine and both suffered from alot of heat soak!

    The best cheapest option is to do the airbox mod with k&n panel filter.

    or if you can be a cheap as me find a very cheap pipercross viper (£50)
    but still suffers sometimes as this part (http://i151.photobucket.com/albums/s...y/IMG_4839.jpg) sometimes comes loose and sucks in hot air again, but hasn't done it in a while lol

    If you want noise, you want ITB's

    On a serious note, cone filters aren't worth getting unless you drive around in the cold alot, and under bonnets in astras they aren't

    Thanks for both of your replies.

    I've already derestricted the airbox. Would I notice any benefits of a K&N panel filter?

    My reasons for considering an air filter were the noise and possibly a bit better response. But from what you guys are saying I don't know if I'll bother.

    What are the symptoms of heat soak?

    Reduced power espeically whilst in traffic in the summer.

    Noise = Open cone filter
    Power = Derestricted airbox, Vectra C Diesel air intake and performance panel filter.

    Performance panel filters...
    K&N, ITG, Courtenay Sport / Piper X
    Its a jam thing

    if you havn't already done it then get your self a new exhaust with a higher flow rate. more air IN - more air OUT! - As for the need for better response then i'd seriously consider a remap - well worth the cash and it'll run loads better. do the air box, filter and exhaust first though.
