Plug wires

[sdeeter19555]

I'm at 60k, have had new plugs sitting on the shelf for this 2012 since it was a month old, never changed them although I bought them to chase my surging issue (which I still have). I am going to change them next weekend and was wondering about plug wires.

 

Then I had an ah-ha moment...I've had a whine in both my cb and my (oe) stereo since new. I had made the assumption it was the alternator. Now I'm wondering if it's a bad wire?

 

Are the preferred wires the OE wires? Or is there an aftermarket option that is preferred?

Me personally I'd stay with the AC Delco's. These engines tend to like OE parts when it comes to engine operation.

OE my preference.

 

Here's a search of this site. Has been discussed much.

I have had good luck with MSD wires, used them on my 2001 suburban, and they are on my current truck.

No real need to change the wires unless there is a problem and it shows they are bad. Mine are original at 166k and it runs great and still gets 18mpg. OEM is the way to go if you do, no need to put on something expensive on a stock engine. Kind of like killing a gnat with a sledgehammer.

I do have a low rpm surge and a whine in my radio...

Well if you changed out to the recommended plugs then the next would be the wires.

I never got around to the plugs, they are sitting on the shelf.

Here's a great resource to help explain the different types, pros, cons, and myths.

Here is my opinion that is not backed up by any scientific testing and is totally subjective...

 

I have Magnecors (Electrosport 80 series, 8mm) on both of my Jeeps and they are a HUGE improvement over the stock wires that were on them with regard to EMI feedback into my communications equipment. The ONLY thing I dont like about the Magnecors is the spark plug boots. After about 2 years, my boots deteriorated just enough to allow intermittent arcing to the head. I replaced the Magnecor boots with thicker MSD Pro Race boots from Summit which solved the problem and the wires were put right back in service. They have been in service for about 5 years now and perform just as good as the day I originally put them on. Enough about Jeeps..

 

When I drive the Sierra, I always listen critically for extraneous noise in my amateur radio equipment . I find the OEM wires to be satisfactory in suppressing EMI most of the time. 99% of the people on this board would not have any issues replacing the stock wires with OEM and they would never miss a beat. However, if you are a wack job like me and you are into mobile amateur radio and need the lowest noise floor you can get, I think you can do better than OEM wires. Being that the stock offering from Magnecor is good but not bulletproof enough as is, next time, I'll be rolling my own wires. I'll be using Magnecor wires and terminals but I'll remove the stock boots and use the much thicker and superior MSD boots that have proven to hold up to the abuse of an underhood environment.
