If your going open cone I'd personally get one of the kits to put it in a area of direct air like mine.

If your just planning on putting it in the engine bay I'd stay with a panel filter in a smoothed box with a larger air intake.
 
Well i am fairly new to some of these issues so still researching.

Will be fitting some new rs4 soon which will be the first real mod :)
 
Well a panel filter and air feed would be the cheapest option and look OEM.....Prob cost you aboutt £65 to do.

A open cone filter and relocation pipe are about £130-225 for a decent one.

Hope this helps :)
 
Iam going to go for a K&N cone and make the induction hose setup myself with universal blue samco hoses and aluminum tubing as i did in my MK3 Fiesta. Iam going to locate mine down in the lower part of the bumper though on the Leon.

I did this but with a 1 piece mandrel bent alloy pipe......my advice is don't do it because it sucks in loads of crap and water when it rains......it killed my MAF sensor to last weekend! :(

I know its going against what I said earlier but I didnt realise quite how bad it was at the time

I've put my airbox back on for the winter now.

I'll find a way around it somehow. I'll find it a nice little space where its not too exposed, away from the heat but will draw air. Maybe use a meshed off cold air feed aswell.
 
The only place would be just as it comes through under the inner wing/chassis leg, if you used a stumpy filter it would just sit higer than the bumper grille.........you'd still obviously suck in crap just not as much as directly behind the grille like mine was :)
 
Thats about the only space there is to be honest, as you can see if you were to go higher you'd prob be touching the splash shield so wouldn't have a great deal of open space around it to suck air from.......any lower and you'd have a great air flow like I had but also risk the problems I had in the bad weather.

Another option is to do it like the picture and buy a K+N Precharger to cover it.
 
The tuning mags have done loads of tests on induction vs panel filters and i have often seen induction kits do worse than the std filter in the box unless they cost hundreds and have very good heat shielding so it is a good choice to go for the panel filter but you wont get that induction roar like an ind kit would.

But I like a challenge :D
