Air filter change? worth doing?

[turboguru]

Hi,

I am the proud owner of a Krypton Green exige with black stripes which you may have seen at Goodwood breakfast club yesterday if you attended with my roof off?

Anyway my question is this.. I have a stage 2 exhaust but the standard air filter and I wondered if I changed to a Pipercross airfilter which I believe costs around £400, is it worth it? will it help the performance at all and will it sound better or worse?

all feedback and opinions very welcome, cheers all

it will sound great and probably give you 2-3bhp (not noticable really) ...keep a look out for a cheaper kit - maybe 2nd hand on here or on SELOC...its worth changing for the noise..will put your insurance up a bit though usually

There are not many "filter kits" that are better than the original lotus design, many are worse. Most of the good ones post gains of less than 5 bhp which can be attributed to atmospherics.

If you are doing it for power gains then it is not worth it, if you are doing it for the noise then go right ahead. SimonK's sounds brilliant!

Be careful with some of the cheaper kits - many of these haven't gone through much R&D if any and in some cases the assembly comes apart with little provocation - you certainly can't afford to have a filterless set up.

Also check the filter type - some are foam, others cotton. Both work well but if you're not one to tinker with the car then bear in mind that foam filters will degrade if neglected, whereas cotton ones just get more clogged up.

Can't add much to the debate re your Air Filter (mine's an S1) but saw you at Goodwood yesterday and thought i'd say Hi Your car looked gooooood BTW.

Cheers for the compliment, it's good to get some feedback on it. I will be at the GRRC event on Sunday too so may see you there :-)
