Etec plugs.

[Caper11]

I decided after reading some threads on other forums about etec plugs to check mine. My sled only has 1000miles on it but when I checked the plugs they were worn. The electrodes were wearing away and opened up the plug gap. Wouldn't think the plugs would wear in that amount of miles.

Mine where indexed wrong, didn't really seem to effect performance but startups and midrange or less throttle was effected.

I was surprised when I bought a set from Napa, and they were indexed bang on. Almost perfectly pointing at the injectors.

actually I believe the "preferred" setup is with ground/opening at 90 degrees to the injector, but anything between 90 on one side to 90 on the other side(a 180 degree sweep) is acceptable, then again i have read that supposedly it doesn't matter, so like any info on the web, handle with care
