CPO 2019 CX5 2.5 Turbo Signature, 33580 miles
- bought vehicle at approx 3000 miles, to my knowledge today's was this vehicle's first spark plug change.
- NGK DILKAR7M8, checked gaps using spark plug gap gauge (coin shaped not wired) and also Lisle Feeler Gauge - all were 0.030"
- installed according to Paul's Travel Pictures (Mazda CX-5 Spark Plugs Replacement Guide - 2017, 2018, 2019, 2020, 2021 & 2022 - Skyactiv-G 2.5L I4 Engine - Picture Illustrated Automotive Maintenance DIY Instructions)
- I did not have to disconnect electrical from the coils.
- Access "Top Plate": I only had to remove the 4x 8 mm bolts. Also there's this annoying hose that needs to be removed for access (red circle is where I detached hose from; had to use a couple of hose removal tools - see pics). After installation I put hose back on but also secured it with a hose clamp
- no CEL after 10 miles, subjectively, the vehicle feels smoother
Check out these photos - tools and also the original spark plugs. I drive pretty spiritedly, but am quite surprised at the wear after approx 30000 mi in my possession.
Based on what I'm seeing I plan to change in 25000 miles.
I'm going to stop by Mazda service to show them. Any other thoughts?
