Today i installed the ngk BKR5EIX iridium ix spark plugs in my 1994 C280. whole install took about a half hour!! not sure about the performance gains if any yet, haven't drivin it much yet, will tell you guys later tomorrow if i feel a difference!! when i pulled out my old plugs they were Bosch Platinum +4's!!!!. I know what you guys are going to say about that:D but over the past year i have had the car i have not had any major problems(knock on wood) so i really am not sure what the big deal is about not putting platinum in the early cars(i understand the specifics behind it though), as i did not put these old ones in. but as of now the iridium ones seem to be working well. will give the car a couple of good wot test tommorow:D :D!!
