Review on NGK 6046 DCPR7EIX IX Iridium Spark Plug - Compatible with 2017 Harley-Davidson Dyna Fat Bob - FXDF by Ryan Springer

Revainrating 4 out of 5

Slight improvement over old spark plugs

My original spark plugs had a large gap at 25,000 miles so I expected a significant improvement in throttle response with these plugs. The improvement on my 2009 HD Softail Deluxe seemed marginal at best.

Pros
  • Wide Range
Cons
  • Wire is shorter than other models
