B58 Ignition Coil DIY solutions

[fmorelli]

My point was - there are a host of differences and yet they still worked until they didn't. The R8 coils also had a push and seat feel which people thought was the coil seating on the spark plug, and it wasn't. I put my time in on this one. Just saying, from experience, don't overlook the nuances of fit if having misfires. In our experience, there was more going on there than was obvious on initial inspection, and it served as a good lesson. Good luck, I'm sure you'll persevere and figure it out.

the SPP209E dont will fit with n54 cover.
there will be need boots with 155mm length.


this would be the part number link for it.

unfortunately these boots have no resistor inside. but since i want to use the original resistor, these boots have to be changed a bit. I will keep you up to date.

the SPP175E could also be used. as these are 169mm long, they would have to be shortened.

I'm thrilled to see soo much activity in this thread since I last checked in on it! nice to know a DIY option could be available soon! thanks everyone for your input.........Question, are any of these checks for the correct coil boot being done on a N55 motor? i'm not sure if fitment will be the same so I'd like to ask that you guys specify which motor you're testing on.

post 18.

better:
-or try post 15 by your own experience.
-or the HU7Z-12A402-A Ford. little bit longer.

but all have no resistor inside......
well nexsys havent resistor,too.....so...

Update- SPP 209E (CPBK206 for the set of 6) Overall a MUCH better fit than I was using especially the plug to spring connection. I did have to extend the skinny coil end about 10mm or so to feel better about it. Other things to note, the cap that goes over the plug well is slightly smallish for it and needs to be kind of smushed over it before tightening down. You also must be more careful with my method since this results in it not being perfectly flat when mounted. I also had to add another 1/4” or so to my spacer to make up for this. It could probably be trimmed off but I’d rather have the hole sealed up. There is another version of these that are 25-30mm longer SPP223E for 2018+ F150 3.5 ecoboost but I’m going to stop with these. I only had time to get the easy bank done and go for a quick spin…

This is where I ran into trouble. As soon as I layed into it I got misfires on cylinders 2,3 I’ll have to recheck everything when I have time. In my rushing I realized I didn’t apply any dielectric grease thinking there was probably plenty still on the plugs. I have not updated the dwell tables but the stock ones should be ok. I feel like this should have been fine and am starting to wonder if the factory resistor in the B58 boot may actually be needed? Someone smarter than me will have to figure that out. Most modern plugs have integrated resistors so I figured it would be fine. I had this issue on my first iteration and the issue followed those two coils to the next cylinders I moved them to so I just bought 2 new ones that I’m still waiting on… Or maybe I should stop being so cheap and buy the rest of a new set of eldors Idk. Hopefully I can get a chance to mess around with it this weekend. From what I understand the other options out there removed them as well? A little help?

cut the spring and put the stock resistor inside!

 

[pysical]

Nexsys does have a resistor inside. The resistor is typically used for EMI so you dont get that static in other electrical components and also sometimes heard through the radio. With the power of the B58 coil already being very high, too much power can cause carbon tracing on the plug porcelain itself.

I think without resistor would be fine for short term but it would be ideal to put one in.

I never really post on here but saw this thread and figured I’d chime in. I’ve been all through this catalog and currently have tried just about everything that would fit length wise. I’m waiting on spp209e still which is for 2015+ Ford 2.7 ecoboost no clue if it will work but looks promising and for $20 I’ll take a shot. I’ve tried raiding the coil boot section behind the counter at the parts store doing comparisons coil and boot in hand with no luck. Currently running spp191e (Audi/VW 2.0tfsi) which are shorter than I’d like but work. The pigtail I got was for a VW cam sensor I don’t remember what year/model. They can be sourced for pennies if you want to wait the month or so from China. Rock auto has been great for all this stuff since most are not typically stocked at your local auto store. I’m still waiting on my precision harness and 2 new coils (took a chance on a used set) to complete it.
For mounting all I’m using is a 1/4 x 3” exterior screw and a 1” spacer in the small unthreaded hole to right of the spark plug hole. Fits perfectly and is very secure with this super simple method. I originally had made a bracket connecting the 3 on each bank but it was not necessary and a pain to change out one coil. You just have to be very careful to screw it in straight on and if you feel it bind STOP. The cover fits with no issues. I planned on doing a little write up once I figured it all out but that’s the meat of it. I’ll update once they arrive Tuesday I’m hoping. Don’t mind my 2 retro eldors on 2/4 I’m still on stock dwell tables

cut the spring and put the stock resistor inside!

As was said there, any reason why the springs in the original B58 coil and the aftermarket boots can't be mixed and matched to include the resistor and have the assembly work as intended?

 

[Dumaurier7]

........Also, since I don't see the B58 option in MHD for the N55, anyone know if the PR option ( dwell times) will be more suitable than the OEM?

 

[pysical]

Putting them in another boot is probably what Nexsys did. I can cut one of my boots open and see whats up. Since we need longer boots, it may be possible to just pull out the spring from the oem boot, stretch it, then put it all back in a longer boot.

no. they dont have resistor inside the boots in the Stock Valve Cover version just for the m18 Cover....why because they use the full stock b58 coil.

Mix the spring of aftermarket with the Stock b58 spring and resistor and put it in the aftermarket boot

pull the spring out. cutting isnt nessesery

you have to cut it to pull the resistor out

i have two friends here with the nexsys stock valve kit. no resistor and burned spring after some miles on road.

ok i have eldors b58 here and i can pull it out. iam waiting for aftermarket boots than i will Mix it with the b58 boot (resistor)

Ah ok. So the stock valve cover kits are going to have issues then it seems like. I may order another set of boots and then try to put my resistors from the b58 coil into them. I mean its just some springs and a resistor. Nothing that couldn't be measured and ordered.

I can confirm SPP209E will work with the B58 resistor installed. I hacked up a single boot of both to try. If I had to do it again I would go with the SPP223E for the additional length. Here’s how it goes…

Shove the B58 resistor small side down the top coil connection side until it bottoms out the fat side. The top of a skinny paper mate pen was just the right size for this but use anything nonmetal you choose. The skinny side of the SPP209E spring is the same diameter as the B58 contacts to the resistor so I pulled it out some and trimmed it down to 75mm or so. Could probably be a little shorter but works. Carefully take some pliers and flatten out the cut coil end. Push that in the plug side on the inside of the spring until the coned part gets past the lip inside that holds it. Besides that I trimmed off the 3 ribs on the plug side and the seal ring on the coil side to get that depth back and remove the additional spacer. Back to a 1” spacer with 3” 1/4 exterior screw and upside down self sealing washer. And that’s it!

I checked the B58 coil box in MHD and tried it out on cylinder 2,3,6 individually. 2,3 worked perfectly but #6 which started me on this journey was up to its usual tricks throwing a misfire code over 6k wot. I don’t blame the coil for this at all but it really put an end to my motivation on this project. I’ve exhausted just about every option on #6 now besides the new crank sensor I’ve ordered.

I don’t want to turn this into a help me thread but before the suggestions come… 09 E90 AT AWD FBO E40 China turbos 25psi, 1500cc 50/50 Meth. New injectors, S55 Eldor coils, NGK 97506 @.018, new vanos solenoids, HPFP holding 2300psi, compression 176-179 across all cyl. Injector seats in head clean and tight. Cleaned all grounds. All items torqued to spec. I’ll have to play with the tune some more. Ive moved afrs, trims, timing, load/boost, vanos, reported torque and lots more with no change. I have confirmed no true misfires are happening by disabling misfire detection after 6k but I will not run it this way day to day. Crank sensor is going to be the last part I throw at it. If anyone has some more ideas I’m open to them. Good luck to all!

Good info @MR-KRAKA

A little bit of research I did...

It looks like the Nexsys kit uses a SPP170E boot. I am guessing only because it looks identical. The only place I found that gave me any sort of length said it was 6.5" which is 165mm. This seems like it might be a bit longer than the boot you mentioned SPP223E which shows 146mm (5.75").

Also, the resistor in the B58 boot is a 1k ohm resistor. I tried looking around to see if we could purchase a smaller one that we can easily slip inline (picture attached) but I can't find anything. Finding some of these would be a lot easier than opening the boots and fitting that larger resistor in them.

Looks like people are removing the resistor in the Cruze world https://www.cruzetalk.com/threads/diy-spark-plug-resistor-bypass-supersparks.14809/

Not sure if anything here helps but I am going to try to fit the resistor in my boots that I have.

Ughh why’d you have do this to me? Ordered… for whatever reason it’s not in the catalog I was using 2013+ Dodge Dart 1.4L

155-165 will work.

it also depends on which b58 coils you have. i have eldor. see pictures. my variant will be picture 3. i will use the top of the stock eldor b58 and for the bottom the half spring of the aftermarket boot.

as soon as the SPP209E I will try to insert spring and stock resistor into it.
