HELP! I'm confused.

I bought 4-NGK LFR6AIX-11 (6619) because others recommended this plugs in other thread.

However, I just found in that ONLY NGK ILFR6A Laser Iridium (3588) fits to my 05 C230K SS and NGK LFR6AIX-11 (6619) doesn't!!!! Can you please help me if I should return them and re-order ones?

Best regards,

I would go by the "factory approved service products" pamphlet that should be in the pouch with your owner's manual. it is generally more reliable threads or
the Bosch plug recommended by the aforementioned factory approved service products manual (for the US version of the 2005 C230 w/ M271) is FR6332. that is what I used.
