How to build a 4g63 Coil On Plug Assembly

This is just like all other do it yourself projects.
1) Buy parts that make doing the job easiest for you. 2) Put the stuff together. 3) Install it.

No really, I used the JMFabrications Coil Plate, ordered all new UF269 Chrysler coils and wiring from Toyota. This video is intended to compliment thread #290665 at DSMTuners dot com which contains wiring diagrams and part numbers for these specific products. The only thing I did different was use 3/16" grommets in the harness holes rather than elongating them to prevent wire chaffing. I went a little overboard with the convoluted tubing, but it looks fantastic.

you can get coils from Chrysler models...

What isn't covered in that thread is the necessity of a capacitive discharge system. In order for this to be any kind of upgrade a CDI is required. The factory coil pack on these cars is good for 30+ PSI.

Jafro, I am about to build a C.O.P. Identical to yours. Could you please tell me where you got the ARP bolts? I appreciate it and the video is very informative.

[Jafromobile]

@bradikus7 Coil bolts are ARP 770-1002 SS 12-point M6x25mm UHL bolts. You need 2 packs.

Cap screws came with the JMF plate.

I bought a big bag of stainless M6 nuts (SUM-HK-M6CNANIZ), and assorted m6 washers (SUM-HK-25NMLWIZ, SUM-HK-25NILWIZ and a generic 25-pack of 1/4" SS washers) not knowing what would fit best. The loom materials, tape and fasteners all came from Summit Racing, and those are the exact part numbers I used. Wires are all dealer parts, more info in the description. (ツ) b

why are the boots on the coils different lengths?

[Jafromobile]

@Blazen8gsx They're different lengths because I did a test fit with one coil installed prior to assembling anything. The standard Chrysler boots are not a perfect fit. You have to trim them. I've got a video for that, too.

smh.. PLEASE NO ONE DO THIS!

[Jafromobile]

@DaPobster Why would you say that? I included adequate warnings for expectations... that the coils are actually not as good as factory coils... There are justifiable reasons (sheetmetal intake manifolds) that justify using alternative ignition systems. Just sayin'.

[bradikus7]

@Jafromobile Thank you for the reply. I just got back from Jegs, can't believe I just paid $32 for 10 bolts and washers haha. Oh well, at least it will look pretty.

Very clean, nice job!

I posted on tuners 2 times and noone replied and i figured since you took several hours to make the video you may know it by heart lol.

[coheed0000]

Jafro i have a question you may be able to answer, provided you still have your old coil pack. Someone did a 6 bolt swap on my car and the coil pack was zip tied down, so in the process of fabbing a plate to mount the coil packs, i took them off of the stock 2g bracket. Well after i took them off i realized i forgot which was the 2-3 and which was the 4-1. On the back one coil has 2 red wires and a blue wire and the other has only 1 red wire. You dont happen to know which is which do you?
