I am looking for new spark plug wires for my 2003 496 mag ho motors..does anyone have a AC Delco part number? Merc wants 500.00 for each set.....

Good luck i went thru this last year on my searay unlike in a car the wires are routed around the exhaust manifolds so ones from a car or truck will not work they are short
only thing i would think of is buy universal wire set and make them to the length you need

Yup I thought I was smart and ordered a set for a 2003 chevy truck with the 8.1 and of course they were not nearly long enough. It just blows my mind to think that they can charge $500 for a set of wires...or you can buy them for $100 each if you only need a few...hahaha its a joke

I think the aftermarket can solve your problem.............for example MSD

MSD's from Teague are under $100.

I just ordered part number 32079 from MSD. I called and talked to the tech dept and that is the plug wire that they reccomend for my application. I will have to put the end on my self and cut them to length which is no big deal I have done them in the past before. They cost $ 137.95/ set from Summit Racing.

Thanks everyone for the help.

It still just blows my mind to think that Merc tries to get $500 for a set of wires that are probably not half as good as the MSD wires

Good info here; thanks. Please be sure to report back on how they perform once installed.

Just wnet through this a couple of days ago. The late 90s Corvette set will fit. Mine are BWD supermags. Part number is CH869. One of the short ones has a straight boot, and is kind of a PITA to get on, but the rest will work.

Late 90s? As in a 1997-1999 Corvette C5 with the LS1 engine?
