Filter kits

[MorpheusGPR]

Is there any cutting needed in the filter kit? How much gain hp and tq is average and whats the 1/4 changes average.

Don't want any permanent marks left.

Thanks.

no cutting required for the airkit alone, we do need to trim the plastic liner for the ram air set up. we seen around .2 reduction with the ram air kit. of course the outside air temps play a big factor with ram air.....
