The reason i dont really recommend is because its tough to do all the work through the headlight housing. its a pretty small space to have one hand holding the res. and the other cutting. definitely DO recommend a dremel!! i had tried everything!!! i ended up using a pair of hedge clippers/small branch cutters and that was easy but alot of damage to the bumper if you dont tape it up good to protect it.. As for a differance i did notice an increase in sound. it was louder for sure. not so much performance wise. but i mean, im sure it helps, its more air. Hope this helps out.
