They were ok while I had them on, but went back to oem plugs eventually. I had to change the coil pack and decided to check the plugs while I was there. I think the pulstar plugs were running so hot, they actually melted the rubber pieces of the coils. That scared me and I went back to oem's. It's up to you if you want to try them angryfx, but I would suggest regular check up on those plugs. Hope this info helps.
