The only thing about the Bosch wires is the name. The wire itself is not special and the resistor ends must be factory seconds as are most aftermarket brands. Probably 1 out of 4 sets of aftermarket wires I have installed have come back within a year, usually due to an open or shorted resister end. I now go back to the dealer.

The first set developed a hole near the end and eventually blew themselves apart. The second set had a high rpm miss on the #3 wire. I haven't been all that impressed with the Bosh wires thus far. Fortunately, they keep replacing them. jim ----- Original Message ----- From: "George Goff" <THX0001@AOL.COM> To: <vanagon@GERRY.VANAGON.COM> Sent: Sunday, December 21, 2003 7:29 AM Subject: Re: Engine Miss > In a message dated 12/21/03 2:43:30 AM, neptunesguitars@SWIFTDSL.COM.AU > writes: > > << Symptoms are start van runs smooth for 30 seconds then miss kicks in. >> > > SyncroPete, > > The symptom you describe certainly would seem to indicate a problem in the > fuel injection control system, but because of an elusive miss which I have seen > in two different vans on THREE occasions, I suggest that you look to the > ignition wires.
