NGK LFR6AIX-11 (6619)? OR NGK ILFR6A Laser Iridium (3588)?
Hi,
I'm a huge fan of this forum and this is my first post to ask help.
I have bought 4-NGK LFR6AIX-11 (6619) because others recommended this plugs in other thread.
However, I just saw in Amazon.com 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,
Cooldad.

Seasoned members may advise against relying on Amazon for proper fitment and cross-reference intel, although in this instance they’re correct.
What does your Operator’s Manual specify?
I’ve had good results with both the ILFR6A and (altered) LFR6AIX-11 in various M271s.
NGK’s ILFRA/3588 is typically MB's OE fitment.
The generic replacement LFR6AIX-11’s (1.1mm/.044”) gap may prove too large to reliably arc owing to marginal coil-on-plug amperage.
Solid first post though. Welcome. :)

splinter,
Thank you very much for your help and encouragement!...though I feel like I fall too much behind seeing the chart.
I think I should then exchange for the OE fitment...right?

There’s probably no real harm from using the less costly LFR6AIX-11, but you didn’t hear it here . Close the gap down to specification.

The M271 requires a plug with 26.5mm/1.04” worth of threads.

+1 on the great posts and thank you for the information. BTW, I ordered the ILFR6A today. it was hard not only to close the gap, but also to measure them all without proper tools!!! Thanks again. cooldad
