[s-cars] 034 high output coils

Wed May 23 23:43:55 EDT 2007

Just last week I installed the 034 HO coils.  As this is my 2nd UrS I had no 
patience at all with farting around with the POSs and the coil packs - BTDT, 
not at all interested in doing any more (NAAIIDAM).  The stock system is 
flawed, and there's a simple (but expensive) fix.  Cody really has this 
covered, but I'll annotate with the very latest info.  I've had exactly the 
same experience - they work great, but the kit is not up to par at all.  In 
summary:

1) Still no documentation, but they did direct me to a link on their site to 
directions for their ill-fated 1.8T coil set, which was enough info to get 
the job done.  But no info came in the box, just parts - I had to call and 
ask.

2) The brackets don't work, and they're still amazed they don't.  I mounted 
mine in what would be considered a conventional position - the high tension 
lines do come out the top of the coils, but in order to do so I had to mount 
the brackets to the face of the stress bar instead of around the stress bar. 
I've asked 034 to make some new brackets & send them to me - we shall see.

3) The coils do mount up to the brackets now; they've provided long enough 
spacers so the coils aren't all cheek-by-jowl  - there's clearance.

4) The plug wires are still insanely long!  I'm amazed that a so-called 
custom app would have wires so long I could put the coils in the trunk.  I 
just snaked them around and they work fine, with no evidence of crossfiring, 
but really, would it be so hard to make them fit???

5) Yes, a heat shield is a good idea.  Electrics and heat are not always the 
best of buds.

6) I've left the plug cover off until I suss it out - I think I'll just run 
the AAN cover & create an insulator around where the wires exit.

Performance-wise it's the cats pajamas - an A+.  The kit is a C-.
