hooker comps, hedman, summit, blackjack, dynomax are all essentially the same routing, 3 tubes under the drag link. the summits vs. the hedmans had slightly better plug clearance. that could easily be production tolerances though. the #5 wire I had to replace the straight boot with a 90 degree one, the #7, I had to bend about 15 degrees.

the TTI's essentially copy the dougs D453 routing. I think the hooker super comps are very similar, also.

since you don't drive your car year round, you don't have to worry about large ice chunks in the middle of the road. I can't really see how anyone smashes tubes in on these things unless you hit something like that in the road...

my uncoated hedmans, while ugly, were still solid after 6 years of year round use. I just replaced with the summits, since I had the engine out anyway, and figured I'd only get another 2 years out of the hedmans....
