IMHO depending on headers or manifolds you dont exactally need OTVC. some say they look nicer others say its harder to work with due to constantally having to move them. i put longtubes on my 93z and went through 2 sets of plug wires before i found the trick. stock ones of course my car ate through them in 15 minutes. that was expected. i bumped it up to morosso 8mm plug wires and just routed them slightly different. those lasted about a week. then i finally got smart and ordered some heat shield boots from jegs and slipped them over some msd8.5mm wires
Here is the results. sorry for the bad pics not much room to work with.
these are the heat boots from jegs.
the tricky part came at the #6 cyl. on teh passenger side ( i believe it was number 6... third one back ) i had to route this wire under the motor mount because the heat boots do not like to bend. this is why i couldnt really do it any other way-

there is not a lot of room to work with
