What plug wire, and coils are you guys running. I need an upgrade! :D I know there's a few aftermarket companies that make wires. Which are the best? Thanks.:p

The stock wires and coils are fine. Anything else is a waste honestly. I actually called MSD a while back to inquire about their DIS systems and they said they tested the Subaru ignition and found no gains from their systems and that the Subaru ignition is one of the best stock ignitions they have ever seen so they had no plans on doing anything for them. They told me to stick with the stock stuff. :) I have no problem with flames getting blown out at 11psi or 50hp shot of nitrous.

Yes the stock system is just fine. Remember, if your plug only requires 10k volts to create a spark, then the ignition system will only generate 10k volts, even if it's a 100k volt system. Most factory DIS systems are capable of 30 to 50k volts.

Suggestion...

Get something to control the stock ignition like the Greddy E-Manage...Look into it, It controls fuel too...Apexi is supposed to discontinue production on their ITC, so get if you want it new you might have to get it now...Results may not what you want...Change the plugs and upgrade the wires if you like but the coils should be fine...I know HKS's ignition is use by a few RS owners...Ask around...

Is cross posting between clubs allowed? :stinky:

After 50k miles of trouble free turbo driving my car started to experience what felt like a fuel cut under acceleration. The problem is that I have a 99 so fuel cut isn't a viable option. The most probable thing seemed to be a fuel pump not flowing properly or an injector failing under the higher fuel pressure. I met up with another club member who has similar RRFPR, pump etc. to do some component swaping. I had already tested my ECU and J&S so just to be sure that the entire ignition system was eliminated we decided to swap over the coilpack and plugs. As I pulled the first plug wire from the coil I saw that the terminal was a nasty green with some pitting on it. Pulling the others I found that one terminal was fine while the other three were green and nasty. One wire had the bulk of the contact arced away. I replaced the wires and wire brushed the coil terminals and then put it back together with spark plug grease. The car runs fine and the problem is gone. Checking the other fellows wires we found one of his was going as well.

I had just checked them in late October. So take a few seconds to see what yours look like.
