Is your H6 buttery smooth?

[Subix]

Just curious but how many here can claim their SVX to be running top-notch, as in liquid smooth with the engine humming so peacefully you can barely notice it's running? (and if so at what mileage?)

I'm not sure if it's because it's a boxer (as I have no other SVX alongside to make a comparison on) or because I most likely have some more coil packs that are losing out but I hopped back into the impreza for a spin and I just want my SVX to run that smooth at idle. (and that thing has 190k on it!) Or better, can it or should it?

Has anyone here ever replaced every single coil pack and can say for certain it made a huge difference or not? I'm about to plunk roughly $600 in much needed new tires and I can't get the idea out of my mind in wanting to go ahead and replace the other 5 coil packs in hopes that everything will run smoother. Of course, that comes at a cost of only $400 ...but given the fact that nothing looked wrong at all with the coil pack I replaced, I can only suspect the others could just be worn enough in needing replaced. It is, afterall... 168k on the same coil packs. It does have a new set of NGKs however.

Is there a general rule of thumb for life expectancy for coil packs anyways?

I'm going to go ahead and replace my gas cap, fuel filter and pcv valve to see if that makes any noticeable difference at all but I'm betting it's completely unrelated and will have no positive effect.

All of my cars run smooth. One more than the others sometimes. My claret especially runs smooth. It has about 123k now. And so you know...I have replaced a single coil pack and it made a huge difference.

My ebony runs mint and idles as quiet as any new car that I have ever sat in...

At idle I've sometimes forgotten my car is running. I can't hear or feel anything. I've gotten into the habit that if I sit in it for a while I take a quick look at the tach to see if it's still running or not, I tried to start it once while it was idling. Not a nice noise. On the road, not so much, but that's mainly due to my huge exhaust leak and the noisy tires I have.

Mine runs smooth once the coil pack warms up

mine doesn't run,

Mine's smooth once it starts. (What's the over/under on how many times you have to turn the key this time? My friends are such cards.)

I've zapped the flywheel at least twice. It's good, but surely not undetectable.

Mine runs pretty darn smooth. Idle is ROCK solid since I switched over to iridium plugs, and I get just a hair over 30 mpg on the highway.

I have just a bit over 120k, and I have no idea if any of the coils have been replaced. I'm curious though about replacing my coils with some aftermarket ones, like the plasma direct coils that some of the other guys run. I figured one for a WRX would work, but maybe I'm wrong?! Is there an aftermarket coil that works with our cars?

If anything, it can't be too hard. Maybe get a clip off another coil harness to make everything work?

my teal one idles/runs/accelerates very smooth. she still has 3.54 gears in there. my friend who drives a civic when he listens to my teal svx warming up in the winter....he said: "wow, that noise is smooth "

but this is what was happened -

my yellow one has double the mileages of the other one. i do feel the difference. it's still okay but i can feel it sounds a bit loose compared to the other one.

My SVX runs smooth as butter. My Legacy also runs smooth as butter. When I drive the 2001 Volvo Wagon V70 Cross country, there's a noticably less comfortable ride, primarily in engine vibration, when I compare to my Legacy, almost identicle cars. Inline 5 cylander vs H-4 or H-6, I think the horizontally opposed engines are one of the key aspects to the smooth ride of my Subaru's.

Smooth as butter. Can't even tell it's running at times. My two legacys are the same. At times they don't even sound like they are running.

i forget mine is running sometimes while i'm stopped. but there are other times where it my idle bounces from 400 to 1000 and i'm not sure what is causing that or why it is only some of the time. Mine needs new plugs pretty badly and i wouldn't be surprised if the insulation on the packs is bad.

Mine purrs at about 800 rpms, also you cannot tell if it's running or not. Its got about 138k on it now.
