Avenger, could you give us a little more info on your plug change?
How many miles were on your old plugs when you changed to the Bosch +4's? What brand/type were the original plugs, that is, were they Champion Platinums, Bosch Double Plats, Splitfire triple plats??? Did they still look to be in good condition or were they pretty used up?
How much of a boost in economy do you think you got?
I'm just trying to decide if going to the Bosch +4's are really what boosted your economy, or if it was just that your old plugs were so wore out/carboned up/increased gap that any new plug would have shown a similar improvement. I'm not questioning that you got an increase, I'm just trying to determine what it was due to. The reason I ask is because I pulled the plugs in my car and as near as I can tell they appear to be original and they still look really good. But the car has nearly 170,000 miles on it, so I figure they're due for a change. But they honestly don't look bad at all. The car is getting somewhere between 20-22 mpg, so they seem to be doing the job decently enough. I'm just wondering if I get the +4's if I'll see an increase too.
Sorry for being so long-winded, bad habit of mine...
