Iridium is a better plug than the Double Platinum?

 

Finer center electrode with the same platinum tipped ground = more consistent spark and same long life. I'm running the AC Delco Iridium plugs in my Tahoe and had them in my Rainier as well. This was before the price was lower than the Dbl Plat.

 

I do like consistency. I'm not seeing it listed for my vehicle though.

 

I'm pretty sure that the 41-101 is a direct replacement for the 41-932/41-993 (41-993 has superseded 41-932). Doesn't come up even on the AC Delco parts finder though...

 

The 41-993 is listed for the Blazers, 41-101 is in a bunch of other GM vehicles, but not listed for a Blazer.

 

You could cross-reference the applications and see if there is overlap. If there is, then the plug will work. If in doubt, just fall back to the dbl plats.

 

I'll stick with what I know will work, haha.

Just ran prices and including shipping, rockauto is 15 bucks cheaper than the local advance... so looks like I'm waiting on parts to get here.

 

hey sean did you order yet ? did ya use the 5 % discount code ?

 

Don't know about any discount code, but no I haven't ordered yet. I realized my friend works at an advance auto or something similar, so I'm waiting on him to get me pricing too.
