The hoses I got were made by [conti-tech??], I think that was the name. The throttle side hose was okay and I used that one, but the head side hose was horrendously made. The two halves of the casting weren't lined up right and the ends were like hacked off unevenly. The clamp didn't have a whole piece of rubber to bite into and the underside barely fit over the nipple when the top side was butted up all the way. The hole for the cold start injector was way out of place as well. I had to get one from the dealer, it was only about $15 and was the more expensive of the two (I believe the pair would have been less than $30). It was an infinitely better fit.

I have also read other posts here relating complaints about aftermarket hoses for the AIC.
