Hi all,

I

 

Simple...put them on and see how they fit. If they don't rub against anything then your all set. If they do then you have to get straight boots. It all depends on your mods and what's in the way (ie headers) and how you run your wires.

 

Well - My custom fit Accels came with both. Certain plugs need the straight boots, and certain ones are ok for 90s... I think with all 90s, even if they'll be safe from heat and whatnot, you're going to have a hell of a time getting them on!
