Default Aftermarket coil packs

Anyone know anything about or used products from Surefire Ignition. I'm considering picking up new coil packs since my OEM coils are splitting and rusting. Is there more consistancy, spark amperage, increased energy?
Thanks!

I'm curious about this as well. My engine builder says the stock WRX/STi coil packs are good to at least 700hp. I've talked with a couple of folks even past that (850whp) that still use the OEM coil packs. That's not to say that adding a more robust system wouldn't yield a few more ponies... or at least some stability.

Thumbs up SureFire coilpacks

Yes I have been running a set of these Surefire ignition coils for over a year now.
I went for the uprated red ones, however I know that Surefire also do an OE spec version as well. Mine are FK0140.
Really happy and the car doesn't miss a beat.

Actually I recently fitted set of FK0186 for my friend as well, who claims he doesn't know one end of a spanner from the other

All good and would recommend. Great price too.
Good Luck.

Thanks for the input Eric. I think I'll give these a shot. The price is great as well.

If your car is stage 2 or less and you are a budget user, these might work, but DO NOT think you are buying either a performance or reliability upgrade as they are 900% suckier than OEM.

Well I am shooting for more than a stage 2 setup. And ignition parts aren't something I want to take a chance on or pay more for if they're really just polished turds.

In case they really are self-hyped, overpriced, K-mart parts OK for a close to stock set-up...I'll stick with OEM. Just wasn't sure if they were actually tested.

I picked up a set of okada plasma coils/ boots just to be on the safe side. Ignition is nothing to be taken lightly.

I'd like to see one of these OEM manufacturers actually provide a cutaway of their coil pack vs. and OEM coil pack and show a test with a simple signal being sent to both and the output amperage measured.

Most manufacturers rely on shiny colors and stickers to sell these things, even if they DO provide a measurable benefit.

My coil packs are over 10 years old, why am I going to risk my motor keeping the stockers?

What do you have done to yours scotty?

d0000000000000000d....you are 'risking' nothing by using the stock coilpacks

buying other than stock MIGHT risk your motor

I have the stock coilpacks in my car which was manufactured 8/2005 and now has 152k miles on it and is now due for new sprat pluds at which time I will inspect the coilpacks and almost certainly put them right back in and keep on goin

I am sure stock coil packs are fine for your stock wrx.
I am aiming for 700 awhp, after looking at reviews/ test results I picked up a set of okada coil packs.

Good for you!

When those fail on you and you go back to OEM, please update this thread, we'd love to hear from you.

Read Unabomber's info in his post above. see his location. sounds like you can buy from him.

Or, https://subaruonlineparts.com/sop-parts/#parts that's for a 2005 Legacy GT but at $82.00 is that more expensive then aftermarket ?

A lot of hurt, scotty like ppl in this forum.

At the shop there is a 6466 sti running the same coil packs I picked up for over three years. The car is pushing more hp than I plan to with no issues.
I am not worried about it.....why are you?
Even if something does happen, the car is just a project. Cars are nothing more than a hobby, I don't plan to make money off of them.

When I finish the sti, one of these is getting an 8285.

Found these aftermarket ones for $199 shipped. http://napolperformance.com/subaru/i...saab-9-2x.html
Also should coil packs last longer than 125k or is it typical for them to have problems at this mileage?

^ The description on these packs seems interesting enough. They look fancy too. I just wish there were comparative test results on them to separate suckering people with there claims vs. real aftermarket superiority. Ignition is as important as a well built turbo, injector, or fuel pump. Yet, where is a graph to prove it like you see in many of these other parts.

We have deviated from OEM coil packs in two instances.

One is some coil packs made in china that "claim" to be OEM. Just for S&G we bought some to test, and they are on my car. Afterall, why not try them at $.000035 each. It was worth a shot. They are junk. They started fine, but have very quickly degraded into misfires and unhappiness. Avoid these.

The other time we have deviated from the stock coil pack is on the race car. In that instance we converted to a standalone CDI box with has the firing controlled by the standalone. The CDI then interfaces to individual coils. Those coils are connected to the spark plug via custom made, and very beefy spark plug wires.

In this case the cost of conversion was astronomical. I would recommend sticking with stock coils if you can.

For those of you asking in the future (like 3 years from now when someone sees this post) no I'm not telling you the CDI box, how it is set up, what the part numbers are or anything like that. If you're going that far we'll likely be meeting up as competitors and I already have enough problems chasing GST.
