if you want noise ive got a baileys trumpet atmospheric dumpvalve and silicone hose fitting kit (samco) you could try but its not the best for the car!!!! but my lord is it loud induction kits on the ibiza cupra imo are a no no as their is no space and no decent reliable cold air sourse i would take the airbox apart and cut and sand the inside of the airbox smooth and remove the trumpet shaped bit of plastic near the maf housing in the top half of the airbox also cut the flap out of the inlet pipe in the front pannel also a must is the green pannel filter jbs sell them £30 is then it is mucho louder!

i dont see what the big deal is with this imo poncy wooossshh noise every1 has it now sounds doesnt scream fast powerfull car anymore! i didnt want any dump noise on mine ;)
 
you got any pictures of this induction kit and the inlet from the standard pipe fitted to a 1.8 t ibza for us to see then :thumbup: :shrug:
 
yeah there are companies that state that there are kits that fit ive tryed 3 of them and personally they were all sh1t and to be honest the best its going to get is how ric 2001 has his dynatwist 1 setup but im talking carbon fibre/polished tubing 2.5" - 3" from the maf to a reliable cold air sourse we still dont have that! look at the amount of kits out there for cosworths escorts fiesta's focus clio's ect ect!
 
For my induction kit i just got a universal one, and hose clamped it onto the carb inlet, then got a bit of industrial 3 inch ribbed pipe and clamped that to the side of the cone, and ran it to the front inlet hole.

Works a trat though it dosent look that professional!
