Installed a set of new Accel 8mm blue plug wires, along with a fresh set of BPR7ES plugs, in the hopes of taking care of what can only be described as a "sputtering" problem; in humid conditions (rain, or melting snow), the car will run fine for a few minutes, and then develop (usually while sitting at a light) a sputtering, like the car is running too rich and can't burn off the fuel. The condition really only seems to affect idle; accellerating seems to (mostly) clear it up, and it goes away after about 10 minutes. The "check engine" light will light up when it first starts happening, and will usually clear itself in a day or two.
Overall, I think I like the wires. The appearance is nice, the silicone covering appeared pretty durable, and the price I got from Summit Racing was comparable to the pricing on the 7mm NGK wires that a lot of people end up going with. Fitment isn't even close to OEM; these wires are bigger, and they will not fit in the stock wire holsters under the spark plug wire cover. However, they come with a set of clips that you can use to keep the wires separated and routed cleanly. I found them to be a wee bit long, but that's a much easier thing to deal with than them being too short.
Unfortunately, this didn't fix the problem. Since I don't have a datalogger, and haven't had the presence of mind to drop by a local auto shop to have the code pulled when it's active, I don't know what the actual code being thrown is. I'm still suspecting a misfire, but it's possible that I've developed a boost leak. When the temperature gets a little warmer, I'll investigate further.
