I just bought a set of high performance ignition coils from bavarian auto. Does anyone have these already? I can't figure out how they are supposed to install. They have a spot where an ignition wire harness is supposed to plug and my ignition wires definitely don't have harnesses. Will I have to start cutting some rubber of of the stock boots? Also, they seem way to big to even fit in the spark plug area under the cover. The coils are rectangular and pretty big. They said when I ordered them that they will work for the 91 318is, but they only sent me instructions for 6 and 8-cylinder engines. What's the deal? Am I going to have to return these?
-
do i have the wrong ignition wires maybe? they were on it when i got the car
-
Got a pic? 'Cause I have no idea what you may be talking about... The ignition wires plug into the top of each coil, AND each coil has a connector at the bottom for the wiring harness to plug in to.
Do they look like the original coils at all? Why did you buy high performance coils, anyway?
-
nevermind man, i figured it out. the 318 coils are at the other end of the ignition wires beneath a plastic cover. i just had to pull the boots of the new coils and then replace the stock block of ignition coils. I just got back from a test drive and these things are awesome! $200 well spent! definite torque improvement in all rpm's, but most noticeable improvement was in he low end, which is where we need it the most.
-
Well, cool.
I just replaced my coils with stock coils, and noticed a bit of improvement at all RPM's and down low, too. At 180+k miles, mine were due to be replaced. I wonder how much of a measureable difference these make over the originals?
-
i'm not sure on the specs over stock coils, but my car has 167k and I'm sure that the coils I removed were the originals, so they were probably a little lacking. I figured if I need to replace I might as well upgrade, can't really go wrong that way. how much were stock replacements? the upgrades were a cool $200, but Bavauto always has awesome customer service and fast shipping so I knew i'd be satisfied. I wanted to upgrade ignition pretty bad anywyas, ut i heard that the 8mm wires were a waste of money and they cost the same as their coils, so i went for em.
-
I scored my coils along with a passel of parts for the timing chain replacement from a gentleman in North Carolina who sold his 318is - essentially the coils and all the parts for the timing chain (guides, chain, etc.) for like $300+. Couldn't tell you what they run, but probably not terribly much less than what you spent. Had I not gotten a smokin' deal on the package I would likely have gone with the performance parts.

I think the OEM bosch coils are around... $58 at bma.
(part #12139066468)
(but, alas, I confess I sprung for the bav auto 'high performance' coils too... they're going to go great with my cone filter!)
embarrasing EDIT: the bosch coils are priced PER COIL, so that's $58 x 4 = bavauto is actually a decent deal.
-
Tells us if you notice the same difference :).
-
oh jeez... here's hoping right...?
I know they'll be great in bumper to bumper traffic on the cross bronx x-way.

:rolleyes:
you should just send them to me then.

I installed the BavAuto HP coils about a month ago too. I noticed the same improvements too. Well worth the $$.
Dan.
-
woot sounds good. As soon as i get enough to pay next month's cc bill it's on like donkey kong
-
Can someone explain how they slightly increase torque and hp? Also, do you just run the regular ignition wires in the car with this? Are there any other reviews out there?
jfdblyu can you post a picture of thenew ignition coils? THanks!
-
i am running the stock wires w/ these basically b/c i heard that the bavauto hp wires were a waste of $200. Does anyone have the hp wires w/ the coils?
I definitely noticed smoother running once i installed the bavauto coils. the increase in performance could depend on the current state of your stock coils. i would take some pics, but my digital camera is workin right. there are pics on the website i think, worth a check.

No pics on the site :(.

on sale $179.95 :)

I replaced my old coils with the bav auto ones... they work fine, and they are a little cheaper than the stock ones... new coils = good upgrade
-
I used another brand I purchased before undergoing the BMW religious conversion. My car would sputter under heavy load at low RPM. I noticed a huge difference because afterwards the car worked like it should. Mine old ones were original because I had to flip the plugs on the wiring harness upside down for the new ones. They used to be M42 specific but along the way BMW apparently figured out they could use one design and sell one part for a lot of cars. Take the extension off, rotate the wiring harness, and plug them in. Some folks are going to the trouble to use them as coil packs with the extensions on them and the whole thing on top of the plug - like other motors. This eliminates the need for spark plug wires but requires extending the wiring harness from the original location on the fender apron to each coil pack. I might do that when I have nothing better to do.

Did you install the magnecor wires before or after the ignition coils? What did you think of the wires?
-
Hey guys, I just bought the BAS coils and Megnacor wires too. When they arrive I'll post my impressions and take some pics.

*edit*
After driving the car for a few days, the car does run/feel better.
Coils arrived yesterday, and I installed them today. Installation was a snap took approx 10 minutes. I can't say there was a much of an improvement, but the car ran perfect before this mod. The car does seem to idle maybe 1 to 5% better, and any hesitation the car may have had before is gone, throttle response was improved somewhat. I think it pulls about the same maybe a little harder but that is most likely a placebo. My original coils had 100k miles on them so it seems they are still in excellent shape. (I wonder if I can sell those) I also ordered the Magnacor 8.5mm wires, maybe those combined with the coils will add some performance. (but I'm not holding my breath). The only other mods the motor has is a JC chip and K&N panel filter.
Maintenance on this car is perfect and up to date.

update
I installed the magnacor 8.5mm wires, drove with them for over a week, noticed nothing. All in all if your car is well cared for and has low miles don't waste your money on either the coils or the wires.
my 2 cents
