I went 8 Delphi 4 or so months ago. No issues I can tell of. I just made my first long highway drive to the VA and pulled 26.2 mpg, so I doubt I have misfires. I get around 12.2 over couple three tanks of gas average on my city, but thats all inner city less than 30 mpg stop and go. Occasional highway burst, if I go to a movie or shopping.

So I think thats a good start for a Cops alternative.
 
A good start, but not nearly long enough to mean anything. Check back at 60K miles and 100K miles. OEM seem to become marginal somewhere in that range, though some do make it longer.
 
When I started reading this thread, I saw all the Info on Cops, and the opinions. So I did my own little research project. I bought a sample off of Amazon (love 30 day returns!) and even tested them the best I could off vehicle (note some old posts about a proper tester). Anyhow, as best I could tell the low cost Amazons I was testing was the economy SMP version. Another member (thanks again btw) bought the set and put em in before me had two marginal behaviors (misfires) in a couple months. Thats when I decide to try Delphi. Thing I I noticed most is they are significantly heavier, making me think they have far more internals than the skimpy one I attempted to cut in half. The springs too. Delphi was 'supple' and easily snugged on a plug. The amazons were stiff, and didn't fit on unless modified a bit or forced. Different wire material I guess.

I predict the Delphis will be a good OEM alternative. (crosses fingers) Course Joe, I will likely be dead before the car hits 100k on em lol.

The ECCPP amazon ones were absolute garbage. I had 6 go bad within probably 4 weeks. Cant expect much for $5 a coil. Replaced with the Delphi and its been about 6 months and they are solid still. Only complaint on delphi was rockauto gave me opened ones from different batches that were dusty. Clearly no one orders them often.
 
Ya, probably the average owner orders the cheapos hoping to get off easy, then few months later I am picking parts off their undamaged (collision) vehicle in the junk yard. The other factor is that probably some may know the OEM are SMP and can be had for just a few cents more than Delphi. To me, SMP may test and throw them in the 'thrifty' pile if not to spec. No thanks!

Thats interesting about the dusty. Mine were completely sealed and wrapped in bubble wrap. I think you did yours before me, so thanks are in order! ;)
 
I think that there is an assumption by some that coils last forever on other cars. However, I do see a lot of chatter about coil problems with some other cars, and strong recommendations to just replace them all when the first one fails or becomes marginal. It seems that even the 4.6 suffers from this, though I do suspect that it might not eat coils quite as badly as the 3.9.

Related to all this, I just recently replaced all six coils on my 325i. At least three of them had become marginal. However, I have to admit that they did take their time, 190K miles and fourteen years.
 
I feel stupid for ordering 6 SMP coils now for my v6... I should have spent the extra $100 for better ones :D

Ohh well, wish me luck lol
 
Back in my flathead days, I used a Mallory coil about the same size as my two fists. It did last practically forever. But when you are using a coil about the size of your thumb...

My Accel yellow COPs now have about 60K miles on them. When I get around to an engine change, I'll try another sort of thing I have in my head.

Depends Seapro. If your talking about the SMP 'thrifty' around 10 bucks, then I wish you luck. If your talking the SMP around 35, then the information I have is that they are the same as the current Motorcraft OEM. So no need to spend extra.

There is no doubt that an overall quality drop happened when Visteon left the game for us.
 
My Visteon coils in the 04 LSE are holding up good. No coil covers either.
 
Update- about 6k miles later and the Delphi's are going out on me. So much for that idea.
 
I have a set of 8 motocraft coils that I have not installed yet as I changed the marignal coils with spectra coils. I do a lot of highway driving...so no issues as of 1000km so far but got the motocraft ones as back up.

I am at 7k and my car is running better than my 2002 every did (at least from my memory as it approached 100k). I would suggest you have some other serious issue. These coils are just to solid to all the ones I compared (which included aurelio). They even fit the plugs better than current chinese Motorcraft.

No matter. You are under the 3 year 36k warranty. Do us all a favor and get with Delphi and have them replaced and investigated and maybe we can have some insights.
 
You had a problem in a month with the cheap ones and after only 6k miles the Delphi's which is basically a GM part is now bad? I think as someone else suggested, you may have another issue going on. I bought 8 Delphi's but have not put them in so I have no experience to give anyone on them yet. It just seems very odd a GM coil would only last 6k miles.

Delphi and GM parted ways a while back. Since then Delphi went bankrupt and was purchased by new owners. I had hopes for them as well, but they definitely are not the same as GM anymore. In fact, there is/was bad blood between GM and Delphi over the GM ignition switch scandal.
 
So Ford/Motorccraft changed who makes their coils and no one has had the new Chinese ones long enough to know if they are good/bad or ugly yet. Delphi parted with GM, the Amazon link above has many reviews on that coil, some good, some bad, etc. Some say the Standard product works, so in reality this is another LS experiment in the making as we speak. This should be a TV reality show, let's see who doesn't get voted off of the island and is the 'Survivor.' Stay tuned! :confused:
 
No other issues ,100% a bad coil on cycl #2. Luckily I have some spares. I did mention that some of mine were sent a bit dusty and out of the wrapping/opened looked like diff batches. Might have been returned at rockauto.. I think I was the first to start ordering them. They said it wasnt a valid return so I ended up keeping them. The others were fresh/sealed.

As for the junk amazon ones they were just that. I think 6/8 went in 2 weeks. What do you expect for $5 a coil lol.
 
Well if that's what you expected out of a $5 coil, then why would you buy a $5 coil? Just sayin. :rolleyes:

Lol.... what I get out of all this is more reason not to be so certain factory parts are worth the premium. True, what is left of alot of our Motorcraft version parts is likely been manufactured decades ago and sitting on shelves some where. Bottom line is do the research who may have made it and decide the price versus reputation is worth it. I am sticking to my Delphi choice for now.

BTW my mechanic who is pretty knowledgeable says SMP makes the current OEM, so I would suggest looking into the more pricey version of SMP as competitive to Motorcraft. I also went with a URO degas bottle this week, think I am glad I did it was 70 bucks and is rock solid (radiator specialist in area gave positive review) , but on the other hand the perfectly good working one I had my mech said was factory installed. No cracks or anything on it - gonna keep as spare.

The Motorcraft thermostat that stealership wont warranty is out now replaced by stant superstat and the system runs at about 200 degrees instead of creeping slowly starting at 208. How the hell do they not see a sticking stat and one that runs hot is not bad? Less than a year old to again support OEM is not always the best choice anymore. 33 bucks then versus 6 now.

Man, you do have to wonder how much Ford is over charging for a plastic bottle ($200+) when someone in China (Ford part probably made there also) can sell a new degas bottle for a LS on eBay for $26.99 including the hose and cap and free shipping to the USA and they are still making money on it. I'm sure it's a piece of crap, but the Ford part can't exactly be an A+ product either, afterall it is the part that all of us are always replacing. It and the other plastic parts should have been made of metal. But Ford knew that and they just enjoy re-selling us parts that we shouldn't be replacing as soon as we do.

Hogwash, they are good for 10yrs. The Lincoln LS isn't the only car produced with near all plastics cooling systems and such others suffer the same identical faith. Even GM has failing overflow buckets. I've replaced one or two in my time. It's still the issue of plastics exposed to a corrosive substance which is in a constant state of heat cycling over time.

Pop any hood on any older car and have a look at anything plastic ... it all ages and all becomes brittle. Just the way it is.

You and Grizzly can knock all the OEM made in China parts or not, still beats any of that cheaper not to spec nor approve crap out there.

But yah, you should buy that cheaper bottle and let us know how that goes.

Not disputing the OEM overpricing but as the saying goes, she whom holds the vagina, wins!!! Ford would be the bitch in this instance indeed.

Also the issue with the much cheaper Dorman bottle wasn't just that it wouldn't last as in beginning to hairline crack, an additional and formost issue was the thread on the bottle at the cap. It didn't allow for a good tight fit to hold pressure. Many have cursed this unit and many have also made it work for a little while.

Of course things do get revised and improved. Potentially later models could very well have been improved. We don't know this to date.
