plugs and wires.
 

What plugs and wires are guys using in the 502 mag mpi? Have back seat and hatch out so thought I would maybe Chang them.. also, any advice on distributers or just cap & rotor??.. 98 272...

Hard to beat OEM

I think my local marina may have put a sierra cap and rotor in last summer.. I lost about 200 rpm when they did cap, rotor,plugs, wires

I have seen some good sierra parts and I have seen some not so good.... I don't have a problem with most of their hard parts, but when it comes to electronics, go oem mercruiser..... MSD makes a good set of plug wires too.
