Exclamation coil pack vs. spark plug wires

hey i was looking at my friends girl friends jetta and saw that she has coil packs instead of us honda kids got spark pug wires!

Well i was think which one is better then the other and dont really know, so i just want to see which is better?

I heard that coil packs are better than spark plug wires so i was thinkin if there better i was thinkin if you could convert spark plug wires in our hondas or acuras to coil packs.

BUT i dont know, So i was seeing what everybodys input on it is!

Thanks for looking

From my knowledge coil packs are best. and are more involved with the cars ecu. I was messing with my friends BMW at bmw and they had all kinds of shit to plug into the coil packs that'll tell you all sorts a things. His car was misfiring. Coil packs last long. And are very expensive..

I'm gonna go ahead and disregard the quality of your OP and give my opinion.

I know on mk3 supras with the 7mgte a lot of guys will take coilpacks off of a is300 and splice the wires from the distributor. It gives a better signal for spark.

If you were to be able to find a honda/acura engine that uses coilpacks it would, in theory, be possible for you to modify them to work.

Lots of people already use coilpacks on Hondas. Various Honda motorcycle coil packs have been used and work great. I can't tell you which ones because I haven't done it, but I think I remember that some flavor of CBR coils are usually used.

You can't use them with the stock ECU though, because there isn't anything to trigger the coilpack (you can't use the spark distribution part of the distributor obviously). People who switch to coilpacks are usually using aftermarket ECUs with individual ignition outputs, and there are various configurations depending on whether the ECU has internal coil drivers or not. I can't think of an easy retrofit with the stock ECU, because it only has a single ignition trigger output (the rest is done by the distributor button).

Whether or not a coilpack is better or worse than a central coil depends on a lot of factors, like whether the coilpack coil is of a winding spec that will give you better spark energy than the single coil you already have, or vice versa. Some of that can be changed with dwell and other coil charging parameters though, so that's not an absolute either.

Coilpacks last a long time, don't really have the failure problems that plug wires do, and usually are shielded so they don't radiate as much electrical noise. The downside is cost, and sometimes failure from high heat. Remember that some coilpacks have an ignition driver built into the top of the coil, instead of having the driver built into the ECU or a separate driver module. For example, most VW/Audi products have a little ignition driver module that goes between the ECU and the coilpack and turns the individual low voltage coil control signals from the ECU into higher current 12V signals to fire the coilpacks.

Does that answer your question?

cool so do you think it would be possible to convert over to coil pack instead of spark plug wires?

nice information! So do you think it would be possible to convert over to coil packs on honda and acura motors?

It's been done a lot, yes. You won't be able to use an OEM ECU though, you'll have to use an aftermarket ECU with a coil output per cylinder. You didn't read too closely.

I don't see any reason to switch though, the stock ignition system can be upgraded with a different coil, and you can keep the stock ECU. So the only reason I would change is if you're going with an aftermarket ECU for some other reason than wanting to use coilpacks..

I think some of the newer Honda/Acura engines use coilpacks if I remember.
