Plug wires

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?

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 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.

      OCI, not when but why?

      By Atlas · Posted

      On the subject of OLM, Gm's OLM tool may be more "informed" than others brands. I recall OLM's in mid-2000's Chrysler products literally counting down a set number of miles. That's all the OLM appeared to be.    I would actually expect GM to be able to explain the parameters that their OLM takes into account from a high level. No, I would not expect them to disclose their software coding or data analysis around their parameters.   So we're talking about two different topics, so to continue the subject on the other one, I'd be curious to know how much "standard particulate matter" in fresh oil is able to be filtered at first start by a fresh oil filter. How much particulate matter is enough to "matter"?   I.e. how much of a "lever" do we think this equates to (variability in particulate content, in fresh oils, between different makes/brands, some which filter less, and some that filter more).   We can say that more particles = more wear = shorter engine life as a logical statement and use that data with a little marketing to scare people into selecting a more refined/filtered oil. Using a similie, is this like deciding to forego two alcoholic drinks in a lifetime because we're worried about the potential impact on lifespan? Are there numbers which translate the ISO test results into a quantifiable increase in wear for a given engine/use case?

      I'm pretty sure it doesn't actually recalibrate the speedometer it just changes the wheel speed sensor inputs to the computer. The truck still thinks it has stock tires.

      I apologize, I missed this post, at risk of going off CURRENT TOPIC.   I'm not saying it is BS, I'm questioning how much information is being held back. GM is NOT going to spell out exactly every parameter in the algorithm. Liability, intellectual property, etc.    I'm not naive enough to believe that it is as simple as revolutions, coolant temperature, miles, time; are you?    I don't do irrational either, and boiling the OLM down to four simple values that I could code in an afternoon (I'm not a coder) is irrational - unless it suits your agenda to ignore it.

      Chris 21 I appreciate your constructive response. !!  😉😉😉   The 6.6 is gas.  Correct me if I’m wrong but by recalibrating the speedo you’re correcting the shift points of the transmission on these trucks.?.

      That is a huge misconception.     Bigger does not always equal safer.  Modifying does not make it safer either, with exceptions.   Think of this.  Your truck in stock form is capable of emergency maneuvers, proper stopping distances, its handling is designed around the factory wheel/tire packages, etc.   37s and a lift?  Now you've affected your braking distances, handling and ride control.  You've raised your center of gravity higher.  Your front visibility is now obstructed more than stock, same for your rear.  Does it look cooler?  Yes.  Does it now work as good as it did from factory on road?  NO.       As for my mention of exceptions?  Say you had a sedan or crossover.  They typically come with all season tires.  If you swap out for a performance all season or a summer tire, you improve your car by lowering its stopping distance (better braking because of traction) and improve the handling (regular and emergency) of the vehicle.  That is an actually improving modification.  My old 2019 LD 1500, I ran UHP all season tires on 20in wheels in a factory offered size.  It improved all aspects of how it drove over the Duratracs it came with from the factory in the stock 18" tire.
