Hello everyone. I am preparing to install plugs in my '05 XC90 V8 with 75K. Does anyone have any experience with Autolite or AC Delco double platinum plugs? Just wanted some opinions on whether I need to spring $92.00 for Volvo or $82.00 for NGK Iridiums. This is the first plug change for this car. I guess I can't argue with the mileage. The car still runs pretty smooth. 18.7 mpg average on the computer readout.
Thanks,
Dana

 

Platinums do last a little longer than iridiums, but iridium is much cheaper. I wouldn't spend the extra if you have a good viable option.

Unless you're running super hot, Copper are the most reliable. Volvo would be the best reliability since they are OEM, you can't really go wrong with them. I use those E3 Diamond Fire ones since they come with a 5-year warranty.

 

Spendind the extre 10 bucks is what i would do. Take the guess work and what ifs out of the picture for a cheap differance.

 

i run NGK iridium, sure they are more expensive but i feel as though it livened my car up a bit more than the Double Tipped Bosch Plat's that where in there.

 

I used the iridiums. Because it is quite cheap comparatively others. It also maintain the durability as well. I always prefer to go for iridiums.

 

A very nice and informative topic i like it very much i love this post thanks for this. I will tell my all friends such a good site.
