I have a 2016 CX-5 sport 2.5L skyactiv with almost 74k that will soon be due for a spark plug change at 75k. Mazda requires the NGK Spark Plug ILKAR7L11 from Mazda with the Mazda branding. The Mazda version of the plug is significantly more expensive vs the NGK that you get at the local parts store.
However, when you look up the spark plug on the NGK parts finder they have they show Part # ILKAR7L11 and stock # 94124 (Actual OEM Manufacturer).
Mazda part # is PE5R-18-110
I have seen the past discussion of using the Mazda branded plug vs the one you get from NGK at the local auto parts store such as Autozone and Advanced Auto Parts. Some say to stick with the Mazda branded version as they say it's optimized for Mazda vehicles. Apparently the NGK version can cause power loss, and loss of fuel economy, including misfires.
So, anyone used the NGK version of the plugs that you get at the local auto parts stores without issues? Just want to get thoughts on long term usage of these plugs like people who have driven with them at 20k plus. Any loss of power, or fuel economy? Any issues with check engine light or misfires?
Trying to decide which plugs to get.
