I've purchase an 8$ coil just to get a replacent one in case of fail,
But iyo which differences between 8$ one and 60$ one?

Coil is a coil, should make its work?

 

One will last for 15 years, the other will last for 15 days.

 

Really?

 

No.

I'd guess quality control is part of the cost...another factor may be the number if wraps in the winding, which translates to spark energy. But your $8 coil may last 50 years, and an M$D could last days.

Price does ≠ quality, and MSD proves that.

 

Sometime you get what you pay for.... Also some companies charge widely different prices for what amounts to the same thing.

But I would expect that a coil that costs all of $8.00 is not going to have a long life much less develop the voltage required.

 

Interested in this, so are you saying a cheaper coil has less wraps than an expensive one? As result? A less voltage on spark delivered?

 

I'm saying it could. If it's much cheaper, the money has to come from somewhere;
*Cheaper labor
*Less quality
*Innovative manufacturing process
*Cheaper materials (either sourcing or quality)
*Less PROFIT

^Some of those factors could reduce quality, others may not.

My contention is that M$D coils (for example) are no better than any other coil...even CHEAP ones. I don't believe MSD's produce meaningfully more power, I feel that they fail way more than OEM....I think you're just padding pockets when you buy one. OEM, is solid quality, but you know there is a big profit margin there too. So, IMO when you get into CHEAP parts, you could get one that is a POS...or you could get one that is reliable...depending on where the dollars were trimmed from.

A coil is a very, VERY simple device, and I wouldn't have a problem buying a cheap one.

 

What did you meant POS? Point of sale?

 

Ha ha..sorry, Piece Of S--t. Piece of junk.

 

hahahaha. Christian you are from Sweden or something right? He means piece of shoot.

I was going to reply to your post but held back because i got the impression that so many on here are "buy usa" types who think just because its made in the usa its better or just because something is made in china is worse.

unless you open the item and inspect it yourself (as was eluded to about counting the number of wraps in a coil) you just do not know if higher price equates to higher quality. I think back in the 80's,when i was in elementary school, it was certainly true that cheaper price imports were worse in the quality department than made in the usa or in my case made in canada.

but things have come along long way and the ingenuity is now coming from within over the pond and in no way does made in china mean low quality anymore. In some things yah but same holds true for some things made in the usa and canada are crap now too.

to illustrate my point, something completely different from automotive, my first business ended up being an import business from asia and reselling with my own label on it in north america. there were people buying thier product from the exact same factory in asia as i was, but charging 1/3rd of me. And, there were people charging 3x me. The product was exactly the same and we paid almost the same amount give or take 10-15%.

So, most of what you see on the shelves comes from the same place, and its it is truly branding....companies literally invest into a "brand" , trying to build a reputation on something other than the inherent quality and usefulness of the product....because it is the only thing they can do to differentiate themselves due to the fact that the product is exactly the same as everybody elses.

Anyway, i agree with the others. price doesnt mean jack. whats inside the device, quality of materials does: (how many windings, gauge thickness of windings, quality of glue used to hold the casement together, quality of metal used for the plug pins....). Many times, they are exactly the same.

Before i get flamed, i want to make a point of acknowledging certain products that are "specialty" products like the brake pad company on here that makes amazingly awesome pads, for a premium price, and they let the product do the talking, not some huge billboard marketing. These guys are great and they will always have a good speciaty following. The size of market is smaller and they have lower production runs which means thier input costs are higher because they buy smaller quantities of raw pad material and therefore have to charge more. But, its not that its made locally or in north america that makes it better, its because the usefullness and materials used work better for the intended application, and there is (unfortunately) nothing that is stopping other lower cost producers from reverse engineering these products, building them overseas en masse and then putting them on the shelf as a premium pad. It is inevitable and for all i know it might already have happened.

And that is ok. We are a global marketplace now, its not the 80's anymore. Competition is good. Slack off and we lose.

cheers all.

 

Exactly.

 

Perhaps, perhaps not. Safelite replaced the windshield on my 99 Mercedes S320. They used a non branded one with all the right sizing and the rain sensor attachment. Rain sensor refused to work. Took it back to Mercedes on their dime and they said that the sensor was fine but the reflective material was not right. Safelight said it was the sensor

Made a deal. If the OEM glass didn't work, I'd pay for it and buy myself a new sensor. They agreed since they felt that they were from the same factory except one had a 3 pronged star and the other didn't.

Long story short, soon as they replaced the glass, the rain sensor clipped on and started working. Why it was supposedly the same spec as OEM and the sensor didn't like it? Don't know but I didn't care.

 

Ha ha
I'm form Italy

 

 

Well paesan, when I first got my car 8 years ago, I had my friend who owns a repair shop install an Advance Auto (cheap) coil in my 89 Corvette..When he put it in he said (don't expect this coil to last more then a year) , and I guess he knew what he was talking about because 10 months later it stopped working ..I then installed an Accel coil and its worked fine for 7 years....WW

 

so which are high quality coil and even optispark:

MSD, ACDELCO, ACCEL and DELPHI?

This is my 10$ coil.. Standard motor product from rockauto

 

the last time I bought a coil he had two differant vendors one alot more money but he told me the same place built them both and proved it to me I bought the cheaper one

 

Same place, sure. More importantly what specifications? I have 10 employees. 2 might be fantastic, 2 horrible, 2 below average, 2 average and 2 slightly above average. All come from the same company

 

I think the only real variance in coil manufacture might be the magnetic wire quality. The biggest difference in the $10 coil and the $50 might be that the $50 unit probably has $40 worth of advertising and marketing rolled into the price.

 

Without knowing the specific manufacturing details, I have found it to be a crap shoot. I have had private label manufacturing done where they put the same product in my bags. It doesn't have the same warranty. I have also had lower spec material used. So instead of 20% product and 80% filler you can get the real stuff which is 50% product and 50% filler. All from the same manufacturer.

If you don't believe that, how do you explain that using Mercedes OE glass works with my rain sensor but "Same Factory" glass won't? I think it depends on what you tell the factory you want for specs and more importantly, tolerance.
