Just case it says they work doesn't mean they do. Do a search on iridium plugs on here & other locations. Lots of conversations about them. Had the same plugs and within 10k miles started getting misfires. Put in Bosch & no more misfires. Also had an 03 that threw misfires cause the PO had put Iridium plugs in. Did this in the middle of a 2800 mile road trip.
Beru's also are known to cause occasional misfires.
Keep in mind parts store lookups go by cross referencing and are not always accurate. Some things are Ok to go with non oem...spark plugs & coils are ones that are not.
