Bit(hing about K&N intake kit

EP370z

First I open package and noticed both tubes had a small dent in them in different areas. Where the plastic 90* angles go to pipe one had burr on inside of tube. Other one had paint/powder coat in treads wouldn't let me start tread. Same pipe also looks like when they flared the pipe they ripped it cause the was a build up of tig weld. Got it on but took more work than it should have. The HKS exhaust went on like butter tho only issue was hanger related but fixed it pretty easy.
