Installed the 02 IED devices yesterday. The install took all of 10 minutes from start to finish, the front "module" tucks in behind the frame crossmember and I secured it exactly like the OE connector was. The rear tucks behind the starter and requires nothing to secure it, just like the OE connector. The only thing to watch, as per the instructions, is not to bend or kink the center section of the 8" device.
Rode about 100 miles after the install and noticed a definite decrease in heat coming off the engine. I rode some last week in colder weather, and there was more heat generated then than after the installation of the 02 IED devices yesterday. Couldn't tell any difference in performance, just lower temps. Also didn't check fuel consumption, with 6 gallon tank, I don't really care if they lower mpg by a little bit as long they keep the engine cooler.
Bottom line is I think they are worth the $80 as a little "insurance" to help these engines run cooler. Eventually I will upgrade this 96 to a 103 with all of the "stuff" that goes along with a good upgrade, including a PC or SERT, but for now, I think the 02 IED's are worth the money.
