RE: Spark Plus??
Umm a lot of people use and like ac delco plugs. I use them my self and they seem good however I have never noticed a boost in performance after changing plugs.

ORIGINAL: hillbillyinOhio Just got the NGK IX Iridium, and i like them so far. only been in for about 100 miles. I have heard of problems created by many types of spark plugs in the blazers, I have never heard of a problem using A/C Delco plugs. I use A/C plugs in all my GM vehicles. |

Platinum is for longetivity. Copper works well on boosted/superchatged engines.
I use AC Delcos cause they worked great for me. My bud installed iridiums on his 2.4 litre Cavvy. kinda of a waste. |
RE: Spark Plus??
I switched to NGK Platinums. I have not had any problems related to them but then I don't think I will, I have heard that they build AC/Delco for GM...

RE: Spark Plus??
Iridium plugs are not hype. The center electrode can be made to a much finer point than platinum which will create a much more consistent spark. More consistent spark = more efficient spark.
The main problem with iridium plugs is that the more affordable iridium plugs have a nickel ground electrode which has an expected life of around 30-40k miles. The more expensive versions have the iridium center electrode with platinum tipped ground electrodes and these can last upwards of 80k miles. For my Bravada, I have AC Delco double platinum plugs. In my Bonneville (Supercharged 3800), I have always run NGK V-Groove plugs and changed them every year. Next year I am making the switch over to NGK Iridium IX plugs and will probably just keep an eye on them as to their life. |
