Is there a downside to a universal air filter (i.e. green cotton for example). I saw one at halfords for £30 but its universal. So i'm thinking, greens a good brand, if the diameter for the maf is right, whats the problem? and if there isnt one... why do people spend so much more on a 'specific' one?

and while i'm on this... what is the correct diameter for a leon cupra (facelift) 180
 
No downside except you will have to fabricate a bracket to hold the filter so that is doesn't just hang from the maf. I've got a Jetex cone, 304mm long, 140mm -120mm diameter taper -£50...
 
B3lsy and myself used a universal filter (i think B3lsy used a HKS mushroom filter), take the top half of the airbox off and fix the filter into the lower section of the airbox, you can also cut the top section to fit close to the filter, thus air from the airfeed will be forced towards it, you also get more induction roar and louder dump noise i think.

I also left the bottom half of the standard airbox in:)
 
sorry to hijack :p
do you find the filters make you mpg go down alot??
 
my mpg diddent go down but then if you wana start changing things to try and get abit more power then you gotta take the fuel consumption on the chin!!!
 
hey people i was just thinking about get an up rated panel filter i.e green or pipe cross, will it make any difference?
 
i have always gone with bolt ons in other cars (but never in a leon) rather than panels they seem to work better to me
