Im currently using a modified airbox atm, looking to change to something else.
What have people tried and what would you say is the best option??

either what your using with pipercross filter etc or something along the lines of an enclosed induction kit like bmc
normal induction kits like k&n etc make the engines run like shit

I also have a Pipercross Viper laying around that I used on my 2.0 for a while if you're interested?

Same as Gregg - Ran a cone on my xe and it didnt do it any favours.
Was much better with an enclosed kit.

My old Green one, engine was responsive, throttle response was better, it just fealt better at top top revs.
PiperX sealed jobbie, well it didn't cough and splutter when it was cold like the Green. It idled perfectly and ran far better when cold.
Engine revs were smoother, not as responsivly jerky on throttle, pulled nice but didn't feel as though it pulled as hard at 6k+.

Thanks Damo might try for a pipercross viper, or bmc. Currently running K & N panel in airbox sounds ok but just fancy a change

just chuck the cheapest cone filter you can get on it. it doesnt really matter and all this heat soak stuff realistically is a load of internet rumour rubbish. must be an enclosed filter my arse.

Heat soak is the biggest load of toss you will hear. The only time heat soak will pose any tiny problem is on a baking hot day sat in traffic doing 5mph, even then the only thing you will notice is maybe some loss of low down throttle response.
As soon as a car is moving, any warm air in the engine bay is instantly displaced by cool air coming in the front of the car.
The only time an engine benefits from an enclosed induction track is when a ram air system is used to pressurise the airbox. This is usually only used on motorcycles and is only really functional over 100mph. Otherwise, race cars run open itb's...
The bogging people refer to is because the engines are running too lean and need re-mapping to suit the new filter as the old induction track was so restrictive, not because of 'heat soak'
The cheapest cone filter will give you same results as an expensive enclosed filter. Dont let anyone else try and persude you (and themselves) by telling you an enclosed filter is worth £200 more than a cone.

Had a cone filter on my XE when it was fired in the corsa.A few weeks later i modified a 1400 drilled airbox to fit and it was noticeabley better.Pulled so much harder and ran alot better.

Yes, clearly speak to Nick, he clearly knows things.
Heat soak doesn't effect a car on idle does it.
Open filters work wonderfull on XE's dont they. They don't effect cold running, or make the response a little jerky at all. They are smooth and operate far better than anything else.

When do you ever drive a car on idle? Its not like you need throttle response around town and in traffic jams is it?
ive driven xe's with cone filters on and they are a little jerky due to the leaner mixture but then again they have never been the smoothest engines in the world...vauxhall throttle response in general is snatchy even on newer cars.
just fit some iridium plugs and an adjustable or uprated fpr when fitting a cone filter. the better combustion and increased fuel should smooth out any glitches.

to answer you reply
a std air box, due to it being plastic will suffer from heat soak on idle, due to the car not moving
an enclose filter made from fake carbon or whatever, will suffer heat soak on idle, due to the car not moving.
a cone filter will suffer heat soak on idle, due to the car not moving.
thats clearly just common sense................

We're talkiing the difference between quite a few degrees in temperature though.
Heat soak creates the initial loss in power. It makes a vast difference.
Its kinda like 1/4 miles and turbos. People bang on a huge IC to do 1/4 miles...
Its like, heat soak people, your IC isn't going to do a damn thing until 1/2 way down the 1/4 mile. Get a Charge cooler dammit so the charge is already chilled on the line.
Even when you start moving, the air inside the engine bay doesn't go away. Its still very hot air, and an open filter will continue to suck in that hot air and loose power. Sure a closed filter will get warm and hence warm the air inside a little more, but as soon as your moving, fresh cool air enters the chamber and cools the overal filter temperature. The filter won't be as poorley effected. If the owner was really anal, they've put heat wrap on the filter -> Throttle body, to keep the charge temp down to a minimum.
