Review on πŸ”Œ Denso 4719 ITV20TT Iridium Twin-Tip Spark Plug, Single Pack by Dan Chunn

Revainrating 5 out of 5

Excellent candles, increased mileage.

After installing E3 spark plugs on my 2014 Mustang 3.7 at 50,000 miles the idle was a little rough. I did some research and decided to try Denso spark plugs. I just installed them and went on a 200 mile journey. The idle has calmed down and at 33.1 the best mileage I've ever had. The price is worth it.

Pros
  • Hands free operation
Cons
  • Questionable purchase for seniors
