OEM / Quicksilver vs Sierra vs DIY MSD spark plug wires

[_vn_]

Hello
I've been reading up on different options and would like to hear opinions regarding spark plug wires. It seems to me that Sierra parts when made for not precise fitment are OK budget option to go with - do spark plug wires fall under that category?
For money extraction reason, nothing else I can't think of, Quicksilver makes kit for 8 wires with 1 separate coil wire being shortest costing additional 25% of kit price :/
I also looked at option of making my own wires with MSD parts - is that an overkill? might cost same to build as to purchase kit + coil wire by quicksilver
Do engines such as mine 6.2L mpi 2001-2004 "eat" trough wires faster? I've had boat for 2 seasons and not sure when previous owner replaced wires and plugs.
Last week when i took wires off to apply dielectric i noticed some corrosion on only some wire connections, i've not done "illumination" mist test in dark to determine which exact wires are leaking if they do, and frankly rather not purchase 1 wire at a time and have mix of wires.
1. OEM/Quicksilver
2. Sierra or other knockoff
3. Make my own with MSD

thanks !

In most all cases I don't buy Sierra parts unless I need it quick and cannot find it elsewhere.
Spark plug wires I buy from the local auto parts store and just get silicone jacket and MSD and many others are offered.
Haven't heard anything about 6.2 being any harder on wires then any other engine

Just my opinion

Well the OEM wires are good and will fit perfectly. Often boat plug wires are longer than auto wires, so if the DIY is precut make sure they are long enough, if you get a bulk roll of wire make sure you have enough to cut the proper lengths.

Never heard that one

Yeah, they are on a wire-by-wire basis. Reason is because car engines don't have exhaust manifolds the same as boat engines. The car wires come straight from dissy and across the rocker covers to the plugs. Boat engine wires need to drop down and go under the exhaust manifolds... Hence they need to be a bit longer.

Never found that to be an issue in all the years I have messed with boats, but Chris/Stony I'm sure your knowledge far exceeds mine.

Don't be so sure of that LOL!
