Hi all
For what its worth i have tried standard air box with green panel filter and i am now running induction kit(jabba).The green panel filter was a big improvement over standard and to be fair to seat they have done a good job on the standard air box,its twice the size of the one i had on my fabia vrs.However i was always left feeling that it was stuggling to get enough air at high revs,mine is remapped and at it felt something was holding back at high revs,only thing i could put it down to was not getting enough air,so i bit the bullet and ordered jabba induction kit(it came with stainless heatshield and JR cone filter),it cost me £170 which is expensive compared to green panel filter @ about £40 but when fitted it looked spot on,and the stainless heatshield does just that,no warm air gets any were near filter,it actually deflects heat away better than standard plastic air box which always felt hot after a good drive.
As far as performance,well i have no air flow logs but it picks up quicker,and not just a little bit,it also doesnt have any more problems at high revs,so that tells me its letting more air in,i wouldnt say ive gained any power over panel filter but it picks up better and revs harder,nothing is holding it back now.
It sounds good,not too loud but good dv sound with my bailey and lots of turbo sound,you can hear it from out side car but its not like say subaru which can sound silly.
At end of day you pay your money and take your choice,£40 for panel or £150+ for induction kit,just be carefull which induction kit you go for,there is good ones and bad,its better paying a bit more i think.I am well pleased with mine and would recomend it,it does everything its meant to and ive had no problems with maff sensors!!.
