coil on plug vs cables

[1sttimedsmr]

well I've wondering if anyone out there could tell me some pros and cons with coil on plug systems versus spark plug cables any info will be greatly appreciate it. just heard that cop are better for performance.

UGH..

COP is alot cleaner looking but the fact that unless your putting down some serious power (600hp or so) your stock system is fine...

Its all about pretty pretty stuff sometimes. But I dont want to waste my time for barley or any performance stuff...

Just spend the money on some nice NGK wires and BPR6ES and your set.

they say that coil on plug is more efficient and it can handle more power, they also say
it wont foul plugs nearly as much as wires will
but on the other hand ive seen very high horsepower dsm's with wires so it really
up to you

 

[woooop]

Coil on plug is ok if you have a dis if not stick with what you have. If your not pushing high horse power save your money for other things. There are other thigs you can buy.

The only time you can properly use a cop is if you have a CDI (Dynatek, M&W, etc.).

Otherwise, use the stock coil pack.

Oh, and please search next time.

Thats not true ! I and lots of other people have used a cop withought a dis. But without a dis it is a down grade from your stock setup. Together is better but better than that is gssxr coils and a dis.

Well, there's the problem. Yes, you can use a cop with whatever setup you want. But why use it improperly and downgrade performance?

I corrected my post.

And to add I wasent trying to be an ass. Sorry I apologize ! To the person who started this post, I spent my money on a cop before i had a dis and all it was bling. Take it from someone who has been there spend the money elsewhere.

its not too common for turbo DSM's because the factory gave these cars a powerful ignition system designed for forced induction systems. COP is more commonly swapped into cars that were NA and needed a stronger ignition system for the after market forced induction or spray added on these cars. in their case its about the same for a nice DIS-2 system or piecing together a COP system, plus the COP system is sweet looking compared to stock or upgraded ignition with wires.

if its for performance, save your money unless your passed 500hp, if its for looks/performance then i'm sure it'll look nice. i've seen some nice setups all chromed out while running through this forum

Ive always wondered why so many DSMers chose to go COP. Without a decent tuning setup and the ability to control coil dwell I dont see where any real benefit can be had. The theory of coil on plug is more coils=more time to charge per engine cycle. The longer time the coil has available to charge the higher intensity spark it is able to deliver. Therefore in theory 4 is beter than 2. If you have control of them. On a stock ECU there wouldnt seem to ba any gain. as no control exists?!

Just my theory feel free to develop your own.

Bling.

 

[turbo23]

Are what point does a COP set-up benefit more than a set of nice plug wires?

 

[nuclearr]

I have read what you all have said and I am still going COP and not for "BLING". I absolutely REFUSE to go buy another set of plug wires. I am sick and tired of changing them every 15000 MILES!!! I might even go make a carbon fiber cover to hide the COP underneath. I also no longer have a mounting point for my coil pack changing intakes.

 

[Defiant]

Never.
COP ignitions save the manufacturer the cost of ignition wires, both in parts and assembly time. The plugs don't give a crap whether there's wires feeding them or not. The makers would have gone to COP much earlier, if the coils had been available. They weren't.

Well, that doesn't make much sense.
Bulk ignition wire is much cheaper than a set of coils.

The plugs don't give a crap whether there's wires feeding them or not. The makers would have gone to COP much earlier, if the coils had been available. They weren't.

So, you're saying that there's zero performance gain to be attained by using a COP set-up as apposed to a traditional plug wire set-up?

 

[90on35psi]

I've been running my COP for a while now with no DIS. Run's great.

 

[dsmfa9nutter]

I run a COP because it cleans the engine bay up. Plus there's a lot less to go wrong, no worrying about wires arcing, no worrying about resistance in the wires, whether the plugs on either end are connected, if the coils are cracked/falling apart, etc. Never having to buy another set of wires ($60+) again is another big plus. Two sets of plug wires=cost for a COP.

 

[jrohner]

I don't see how anyone thinks COP looks cleaner. If you just put your spark plug wire cover on, how can any setup look cleaner than that? The 2G's do look kinda crappy how they have the coil and other plugins right on top, but 1G's look great stock.

 

[1sttimedsmr]

this is where it gets so confusing some say cop on stock ignition is a downgrade some say is not , well the truth is out there and I'm planning on finding it. the only reason why i kind of hesitate to get cables, is because the all have some kind of resistance and they go bad, no matter how good they are.I've heard of these cables with no resistance, don't know if its true or not.36-1422MPG - Granatelli MPG Plus Spark Plug Wires

While the DSM's stock ignition system is more than powerful enough to handle tons of horsepower. The fact that wires can be damaged causing a missfire, pop off the coil causing a missfire, plugged in incorrectly causing a missfire. The stock location for the coil is horrible due to the amount of heat it sees tucked away inside the intake manifold. This alone is more than enough reasons to switch.

Now, I agree that in stock form, without the use of an ignition amplifier such as an MSD unit or others that COP is not an upgrade. I do not believe that it is a downgrade either. I would consider it an even trade. The concern with COP with a waste spark system as is stock with DSMs is that the dwell time that the coil has to charge up is not as long as a system that only fires the coil once per cylinder per every 2 revolutions of the crank. I do not believe this to be a problem since the stock coils fire just as often and do not have a problem with missfiring. The dwell time will be the same but instead of firing one coil twice you will be firing two coils twice. So then the concern is that you will blow the power transistor with all the current being drawn through there and that it is not designed to handle it.

Well let me tell you something guys, I have been running a homemade COP setup for 2 years now without a failure. I actually recently swapped my plug wires back on after I had changed my spark plugs and low and behold I get around the block and one of my wires had popped off of the coilpack creating a missfire at higher RPMs. Swapped back to the COP setup and it purrs like a kitten.

Cliffs notes
Stock Ignition: Are good for high horsepower. More parts to break
COP: Not an upgrade and not a downgrade. Less parts to break, less chances of missfires.

 

[Defensorfortis]

sorry to say i must agree COP are bling and you wont find near as much problem with missfires

The people professing cop works without an ignition box are more than likely on low boost levels and small turbos. A set of ngk wires cost $32 from Napa when I bought them a few months ago. Stock coil is reliable, powerful, and already there.

My cop worked, but after trying to make any kind of power it broke up. Rather than drop a few hundred on to of the cop for an ignition box I just put a stock coil back on and left it alone.

Making 550whp with stock plugs and no breakup yet.Save your money you don't need worry about a cop setup.

 

[92AWDHX40]

Your stock set up is fine, 300 to 350hp, wheel horse power, is sufficient, i would say over that youll have poor ignition problems, misfires, stumbling, or sudden rich spikes, but thats my 2 cents.

Stock ignition has been proven to go much higher than that. A COP will offer no benefit over stock without a CDI box and that is minimal at best. It is an aesthetics modification...if you need a CDI box you would need it either way, not because our stock coil is weaker than a COP setup.
