Which induction/filter

The K n N was getting old so replaced it for an ITG foam job, and i reckon i may of felt a lack of power?. I'll never get a bath sponge for a filter again. This filter was sprayed with a sticky aerosol and having it on during the summer its got dead fly's a all sorts of crap stuck to it!. Blitz do a good one and had better be ranging from £209-400. I see H.K.S mushroom used a lot but heard they're sh-t (sponge). Back to K n N, any thoughts?. Oh, any idea which ones are good for removing gunk with an airhose from the inside?.

what car are u putting it on?

what ever u buy make sure its fully enclosed other wise u r wasting your time

Nissan Pulsar GTIR- Attached to AFM, No induction just flexi pipe from front brake duct. Heard of one that can be restored to filtrate as new simply by blowing from in-out with pressurised air when removed.

Get a sealed forced air kit, ive heard theyre pretty good.
