I do like the zip ties because they provide a cleaner looking install and you will have zero clearance issues with the bpv hose, engine cover, or other areas. The only real concern that I have seen using standard hardware is at the BPV hose.
ahhh, okay. thanks! i have an 08 wrx, so i don't need to worry about the engine cover, but i didn't consider any BPV hose clearance issues... it'll be more fun to machine the zip tie channels in anyways.
it does look cleaner with the zip ties too.
