whats the difference between the 2v part# 140032 and the 4v part# 140034?

also i was trying to find the overall under hood pic of the coils. the on that shows the entire motor compartment. i searched accel coils in the ls section and get like 11 pages of topics.

dunno the difference.

Here's the thread with some pics I took of the accels installed:

Iirc the boot is the difference in the part #s. I've had the accels for a little over a year now and my first one went legitimately bad. Cost me $28 to replace and 5 minutes cuz my coil covers are removed. Totally worth it, even if it doesn't give a big performance upgrade. I just got my high flow cats in though, and ill have a new exhaust on by months end - then I'm taking it to a dyno for a tune before winters end (got rear-ended by a drunk driver - no real damage but its worth $700!) So we'll see if the coils do provide a boost (combined with everything else)
 
so just to be clear the 4v has a different boot than the 2v and will not work correct.
 
i had the same questions y'all did except that in my expierences the accel products didnt hold up. anyways i emailed msd and this is the answer that i got back. this is for a 2001 ls8. new coils can make a difference but make a much bigger difference if you have a driver for them. also fords have a multi spark ignition on start up only. so keeping the coils at a cranking condition will in turn give you multi spark yes but just installing a coil wont tell the ecm to do that so dont see how that will help much.

Dear Sir:
Replacement coils for that application will be PN 82428. This is a kit of 8 coils, you will need one each set.
The ignition system you will need for that application will consist of:
2 each DIS 4 ignition boxes, PN 62152
4 each tach/fuel adapters, PN 89121
An optional harness that will make the installation much easier is PN 88813.

Thanks,

MSD Tech
 
Just remember if you go aftermarket coils you have to swap the coil wiring! There's an article somewheres around here on it. Its only a 10 minute job, but it makes all the difference in the world! I ran accels for months with a slow crank until I rewired it correctly. Cranks better revs smoother and no more coil issues! Ill see if I can find the article in here..

Yea, I remember that, Sorry I never updated my write-up. I'm going to have to get to this at some point.

To answer some peoples questions yes, accel coils will work on the v6, it just takes some extra work. The good news is once you get it complete you'll have two coils leftover in case some fail in the future(which hasn't happened yet to me, still running strong). This is the longest I've had my car and not have a coild start failing and they were used coils from another member on here! I think that using non-ls coils on the LS is bad for the ecu if you don't fix the wiring issue.
 
Coil Wiring

These last few posts are VERY important for those of us who are planning a bunch of modifications.

For what it's worth, I've been running Accel coils without the wiring mods for more than three years. It takes about three seconds of cranking for my car to start, and I've recently noticed a hint of stumble while on the expressway, in fifth, under load. I have NOT thrown a code yet. Expressway mileage is around 24 though I've seen as much as 26 on a trip back home from Chicago.

I'm planning to go to a chibby-style coil set-up, using aftermarket coils and plug wires and constructing a set of coil-mounts to be bolted to the cam covers.

Thanks, guys!!

Cam, the long cranking was experienced by me before I rewired my coils. Even if you are going with a chevy style coil-near-plug(I assume) it's still worth your tire to rewire your current coils in the mean time.

The person I bough my coils from ended up having to replace his ecu to make his car start right and I can't help but feel it was because the coils being wired backwards puts addition strain on the ECU.

This is just a suggestion, and if you do rewire please post your results.

Thanks.
 
My schedule is such that I won't get to it for several days---maybe next weekend. I'll post results when finished.
