:iagree:^Correct as always!
Once again you are blowing up bench racing "facts" with actual real world knowledge. How mean...... |
Sounds good! Thanks for the additional info!

I put these in my X5 last year and my mileage went DOWN.
|
Because you foot got heavier?

In contrast, I got better fuel mileage with Iridium spark plugs.

Me too but that is just a small sample.
I would recommend that anyone who have a drop off in fuel economy do a recheck on plug gaps, coil connections, pull codes, and perform a good visual for vacuum lines etc not connected. |

Bump for more exposure as way too many owners of X5 left the normal fall maintenance of plug changing time to "it now winter and I have hard starting etc." Gee maybe when it is warm you should do all the pre season prep work like oil changes, Oil Separator, vacuum lines, cooling systems, brake, air intake checks? NAAAAAAAaaa wait until it is really cold then do it.
Now I am off to fix a no fuel pressure isssue after hand washing issue.... looks like pump, fuse, relay? Testing we will go, testing we will go,....... |
Here's a link as a follow on to this discussion: https://xoutpost.com/bmw-sav-forums/...ium-plugs.html
Pulled iridium plugs after 36000 miles and the gap had opened up .020"+ and the electrodes were melted. Some suggested they were fake as I purchased from Amazon. Maybe. I don't know. I'm going to purchase a new set from Rockauto.com assuming they have a higher probability of not being fake and see what happens. If they were it could be why my mileage went down when I installed them. |
